General Manager /WCR Shri Ramesh Chandra and Additional Member /Telecom Shri K.S. Krishnakumar graced the inaugural session of TCSC meeting. ED/Telecom/RDSO welcomed the distinguished guests, members and special invitees of the 38th TCSC. He thanked the West Central Railway for hosting the meeting and providing excellent support at a short notice. General Manager / WCR and AM/Tele /Railway Board addressed the meeting.


Address by GM/WCR: GM welcomed all the members of TCSC. The following important points were brought out by GM.

1. Telecom is changing at a very fast pace with new innovation and products are being rolled out rapidly. We need to adapt very fast before the products become obsolete.

2. Issue of WPC license fees need to be taken up by Railway Board with appropriate authority.

3. RDSO approval for passenger amenities items makes the prices of items relatively high. Therefore RDSO approval may not be required for such non safety items. A decision in this regard may be taken by Railway Board. GM cited example of Kota division where the video display boards have been provided which are also generating revenue through advertisement.

4. Shortage of staff is brought out for signaling on many occasions. This may be tackled by re-deployment from telecom as telecom activities can be out sourced.

5. Performance of Airtel CUG is area of concern.

Address by AM/ Tele: AM Tele thanked WCR for organizing TCSC meeting. AM Tele appreciated that WCR has demonstrated its capability for organizing large meetings such as TCSC. The following important points were made by AM Tele.

1. Railway board has given mandate to Railtel to provide centralized passenger information system at 2000 stations on revenue earning basis.

2. Passenger amenities items are expected to work 24x7. Due to problems of poor quality, bad performance and lack of support by vendors, Railway board had taken a decision for developing RDSO specification for passenger information system and subsequent approval of vendors to overcome above problems.

3. The matter of WPC license fees has been taken up and it is decided that a nominal license fee will be payable for VHF sets used for applications other than driver guard communication.

4. The network problem of Airtel is a general problem with all the mobile operators.

After initial addresses GM/WCR left the meeting, the first two items as given by Railway Board, were taken up for discussion. These items were,Performance of Mobile train Radio Communication and its way forward and Ongoing ISS works review. After discussion on these items, discussion on 38th TCSC agenda items was started. With the start of formal proceedings, Shri D K Gupta CSTE CORE was elected as chairman 38th TCSC meeting.

AGENDA FOR 38th TELECOM STANDARD COMMITTEE MEETING (2015)

FORMAL ITEM Item No. : 297 (iv) Subject : Draft Specification No. RDSO/SPN/TC/84/2008, Rev.

0.for Router.

File Reference : STT / DATACOM / 551 / Vol.-II Agenda : To considerdeletion of the specification for Router. Notes by Secretary: Draft Specification No. RDSO/SPN/TC/84/2008, Rev. 0.0 for Router was prepared as per Railway Board’s Letter No. 2006/Tele/TC/1, dated 28.07.2008, in which RDSO was asked to issue specification for Datacom Equipment like 2 Mbps modems, LAN Extender, Routers & LAN Switches to cater the need for last mile networking of UTS, PRS & FOIS. RDSO had issued specification of Router on 28.08.2008. At present most of the locations on Indian Railways have been provided with UTS / PRS connectivity and requirement of Router has drastically come down. At present due to its wide presence, RailTel is able to provide Ethernet connectivity at most of the stations / locations. It is also a commercially off the shelf available IT product which does not required specific customization for Indian Railways. Product is also not manufactured specific to Railways. Moreover features of such equipments are rapidly changing as per technology development in IT industry. Zonal Railways may form the requirement of ports / features etc. as per need and finalize the demand as per latest trend in the industry. In view of the above, it is proposed that Specification No. RDSO/SPN/TC/84/2008, Rev. 0.0 for Router may be withdrawn.


Railways Comments and RDSO Views: Sr.No. Zonal Railway Comments RDSO’s View

1 Central Railway 1. DC Routers with G-703 ports for all type of networks. 2. Not Agreed for Deletion. Unless Railway has a tight technical specification, it will not be possible to avoid poor quality products. The specification released by C&IS Directorate Railway Board through their letter dated 16.4.2008 may be used as reference and we should update our specification to ensure procurement of desired quality hardware.

1. Railway may form its features based on specific requirement of Zonal Railways. 2. Railway may form its features based on specific requirement of Zonal Railways.

2 Western Railway As per the directives of C&IS Directorate during 2007, in the matters of computerization, the directives issued by Directorate’s other than C&IS need not be followed. After that letter, the specifications for Routers have been issued from Railway Board on 16/04/2008 and by RDSO in Aug. 2008. It is requested that a letter from Telecom Directorate may be issued that specification for Datacom Equipments as issued by RDSO will only be applicable as Data networks are required to be installed and maintained by S&T.

Issues of Guidelines regarding use of equipment are under Railway Board’s purview. As per Railway Board guide lines Specification of Datacom Equipment (2Mbps Modem, 64/128 Kbps modem and LAN Extender) has been revised in consultation of CRIS. Since Router and LAN switches are not only used in low data intensive UTS /PRS application but also used in high data intensive application like Railnet/Intenet,


Sr.No. Zonal Railway Comments RDSO’s View The specification also needs periodic revision as they are more than seven years old. Some old protocols like RARP and frame relay may be dropped from this specification. Specification may be retained.

CCTV application where video streams are also transmitted, these items are kept separate from CRIS’s purview.

Subject: ‘VHF based approaching Train Warning System for track maintainers’ as per RDSO/SPN/TC/105-2015.

Agenda: Discussion on Specification No. RDSO/SPN/TC/105-2015.

Notes by Secretary:

· During 31st GCM held at RDSO/Lucknow on 17-07-15. Member Staff said that “Around 350-400 trackmen/ESMs get run-over every year and this is a serious problem. Indian Railway needs to develop some warning system so that trackmen get pre warning of approaching train with indication of UP and Down direction.

· A trial in this regard was conducted by South Central Railway, using a VHF based system in KZJ-SC section. Further MS said “RDSO can examine this system and standardize the same to save precious human resources that are lost every year”.

· Patrolling on Railway Track is performed throughout the year to ensure safe running of trains during all-weather conditions. There have been cases of loss of life due to train hitting maintenance staff while performing duties. This equipment will give an advance Warning to maintenance staff about an approaching train in mid-section through hand held VHF receiver unit so that maintenance staff are alert about approaching train. This equipment will be helpful to protect precious life of the railway staff-working along the railway tracks.

· RDSO specification RDSO/SPN/TC/105-2015 for VHF based approaching Train Warning System for track maintainers’ has been developed for this purposeon the basis of inputs from Track Directorate of RDSO ( User) and field trial report of SCR.

· The system as per this specification will give warning of approaching train to the Track Maintainers working on tracks in mid-section on UP or DOWN Tracks. Encoded Messages will be transmitted from the VHF based Transmitter Unit to Receiver Unit. Receiver will give Audio, Visual indication and Vibration Alert to track maintainers/ maintenance staff. It would help to protect precious life of railway staff at duty on the tracks by providing advance warning.

· The system works in VHF range at frequency of 160.450 MHz. · Processing of proposal & sanction of work under Plan Head of Engineering shall

be carried by engineering department & availability of funds shall be ensured. Procurement, installation and commissioning of this system shall be carried out by Telecom department of Zonal Railways.


· Expression of the interest for development of item/vendor as per this specification was invited and offers of 7 vendors have been received and are under scrutiny.

· With the above background Specification is put up for discussion in 38th TCSC. Comments of Railways & Remarks of RDSO

INFORMAL ITEM Item No. : 2.5 Subject : Draft Specification No. RDSO/SPN/TC/61/2015, Rev.-4, for

Integrated Passenger Information System Notes by Secretary: Development of Specification of Integrated Passenger Information System was started on instruction of Railway Board vide letter No. 2004/Tele/TCM/1, dated: 27-12-2005. Based on recommendation of 33rd TCSC meeting & approved by Railway Board vide letter No. 2004/Tele/TCM/1, dated: 3-4-2006, RDSO/SPN/TC/61/2006 Rev.-0 was finalized & issued. Subsequently, Revision- 1.0 to specification of IPIS was issued on 19-9-2006 incorporating following modifications:

a) Two CCU included working in standby for better reliability of the system. b) Three different colors of LEDs i.e. Red, Orange & Green included for

various type of display boards. c) Size of main display board & At-a-glance display board reduced to make

it more compact. d) Uniform protocol included.

Revision -2.0 was issued on 15-7-2007 incorporating recommendation of 34th TCSC meeting to incorporate following modifications:

a) Two CCU of included for better reliability. b) Detailed specification of LEDs with more colour. c) Endurance test (Burn-in-test) of sufficient duration included for acceptance test. d) System should be capable of connecting & driving LCD/Plazma TV beside LED type display board. e) Surge protections in bigger sizes of display boards.

FurtherRevision- 3.0 was issued on 27-9-2012 incorporating following:- a) Colour of Coach Guidance Display Boards(CGDB) was changed to

white with SMD LEDs as it was advised by some of the Railways that red colour CGDB placed across the platform are sometimes misunderstood as a signal by train driver.

b) Face of CGDB was 5 degree vertically tilted for better visibility.


Subsequently Railway Board advised to make IPIS system of the different vendors interoperable and standardize software of the system. Also SMD LED is now easily available which is more efficient and low heat dissipating, which is also cheaper and easily available in the market as compare to conventional LED. Presently data connectivity to various display board is on serial interface using RS 485 protocol. Data transfer on serial interface is slower hence to take advantage of faster data transfer Ethernet interface is considered for data connectivity between central data controller to data hub and display boards using TCP/IP protocols. Installation and maintenance issues were reported for coach guidance display board to address this wireless connectivity is being explored accordingly Revision-4 to the specification of IPIS was processed and is under finalization incorporating following major changes. A-Only SMD type LEDs for better Performance, low cost, availability & low heat dissipation.

i. White LED for all Display boards . ii. Amber colour too can be used for all display boards except CGDB ,if specified by

the purchaser .

B-Data connectivity Wired or Wireless

CDC to PDC & MLDB Data transfer only on Ethernet.

i. PDC to PFD on wired using Ethernet or wireless using Zig-Bee module. ii. PDC to CGDB either on wired serial interface or on wireless using 2.4 GHz Zig-Bee

module in license free band.

Ethernet based Data Hub having 8 ethernet port and 8 RS-485 ports &2 fiber ports for faster data transfer

C-Standard 16 x 48 LED Matrix module to be used for ease of Installation, maintenance & transportation & low inventory

D-Thickness of all PCB may be reduced to 1.6 mm from existing thickness of 2.4 mm for cost reduction because with use of SMD LEDs, component weight & heat dissipation will be reduced.

E-Two lines & each line LED Matrix 16 x 192 to be used for At-a-glance display board. Standardization of data transfer protocol to TCP/IP for interoperability & easy health monitoring of device F- MDCH & PDCH can be replaced with Ethernet based data hubs for faster data transfer and cost reduction. To ensure interoperability, common protocol shall be used & Interoperability Test has been added.

With the above background Specification is put up for discussion in 38th TCSC.

Eastern Railway a. The software should be standardized and unique for all suppliers.

b. Data logging and storing facility should be there to log the time and the action taken by the operators for displaying information and announcement etc.

c. It must be specified that maximum number of nodes (display board of difference type) can be handled by the server within a particular time frame to display after command is originated from console for display.

d. Project implementation and sales service is very poor for the existing approved source. More approved sources to be developed.

Agreed Agreed, feature already exists for visual information being displayed. Not required Already sufficient vendors are approved. Adverse performance of any specific vender can be addressed.


2.0 Reference of sketch of system architecture (available at Page-59) should be made at this point. As per the schematic at Page-59, the communication protocol for data transfer from PDC to CGD is either RS-485 or Zig-Bee. RS-485 is serial mode protocol and the data transfer from PDC to last CGD Takes considerable time (in the order of minutes). This is annoying and it is desirable that the CGD display the coach information instantly. So this protocol should be changed to TCP/IP. 3.8.2 The intensity of illumination of LED light output should be specified

Data connectivity to CGDB on Ethernet will complicate the wiring, extra hardware and cost. As the number of display boards is more. Intensity can be adjusted depending upon the site


Zonal Railway Comments RDSO’s View objectively in measurable units (Lux) and total light output required should also be defined in Lumens. Also readability should be specified objectively in measurable terms/units rather than subjectively. 3.8.3 Following characteristics should be added - 3.8.3.1 The body of LED should be colourless transparent. 3.8.3.6 Background colour of the LED display board should be Black matte with reflectance less than 10%. 3.8.3.7 Glass cover of the LED display- transparent colourless. Note -The reason for colourless transparent body LED and glass cover is that because insunlight the defused and coloured body of LED/Glass cover reduces the contrast of the display to very unacceptable level. Colourless transparent LED/Glass cover alongwith black background avoids this problem.

conditions. Agreed: All aspects already covered in the specification. Agreed:

6.SE Railway Others comments

Audio Announcement System – In RDSO/SPN-61/2011 Rev3.0 at Sl.No 3.5.4/3.6.4 expected time is designed for 4 characters consisting of 2 nos. audio file. Due to this meaning of announcement in regional language differs from actual. Hence it is suggested that these 4 characters should be designed in single audio file. That means in each language 1440 Nos of audio files for the complete time period of 00:00 to 23:59 to be designed

Agreed to come out of this problem these voice files of hour and minute and status (i.e. bajkar, baje etc.) recorded by same announcer should be used.

Train Indication Board – Presently train name field is selected from the FONT. Due to this deformation of pattern of the character of the regional language arises. Hence introduction of bit MAP Technique is suggested for the train name field.

Agreed character codes including special shall be generated using BIT MAP or StdUni-code may be used.

NWR also advised to elaborate “Earthing” arrangements same was agreed. SECR pointed out for use of transparent & colorless body of LED used for display boards because colorful LED body reflects colour light due to reflection during day time when it is off, same was agreed. Recommendation of the Committee: All the members agreed with above suggestions as given in summary of discussion, to finalize RDSO/SPN/TC/61/2015, Rev.-4 and development of vendors as per revised specification for Integrated Passenger Information System.



INFORMAL ITEM

Item No. : 2.6 Subject : Specification No. RDSO/SPN/TC/104/2014, Rev.-0.0 for On-

Board Wireless Public Address (PA) System for Passenger Trains Notes by Secretary: Presently, announcements & play of music inside Rajdhani/ Shatabdi train coaches is being done from a wired Public Address (PA) System which get disturbed during re-shuffling of coaches for route change/maintenance. Railway Board advised vide letter No. 2010/Tele/9(1) pt., dated 10-1-2014 to be develop such system to maintain integrity of train rake in such conditions.

To rectify this problem, Specification for Wireless (Wi-Fi) based On-Board PA System has been developed to provide wireless connectivity between all the coaches of a train and On-Board Wireless Public Address (PA) System for announcement of GPS based train running status, station passed, approaching station, general announcements regarding passenger safety, Cleanliness and any emergency live announcement & display train running information inside the coaches on LED display boards.

· The system will work in client-server mode. · Two master units (1st AC coach or Brake Van or Pantry Car) placed in

different coaches will communicate each other in such a way that they can work in standalone in case of failure of one master.

· Master will establish a WLAN with clients placed in all remaining coaches & maintain its integrity.

· Details of coach /Locomotive ID with MAC ID shall be fed into server of the master.

· Coach information can also be updated through a web-based application which can be uploaded to the server of master device/equipment

· Coach /Locomotive ID corresponding to the rake of the train can also be fed from central server of COIS to the master server.

· System is independent of coach shuffling. · Message being broadcasted through PA system of one train will be not audible

in adjacent trains. · The system has provision of messaging to train administrator in case of

emergency for passengers from Emergency Call Box provided in each coach.


· The system will be compatible with the existing PA system. · It will retrofit with existing PA system provided in Rajdhani/Shatabdi Express

Train. · GPS based train running information like status, station passed, approaching

station, general announcements regarding passenger safety, Cleanliness and any emergency live announcement can be performed

· Train running information inside the coaches can be displayed on LED display boards.

· As the system uses WLAN for IP backbone hence other IP based onboard systems like surveillance Camera & Emergency communication/messaging services can be easily augmented.

· RDSO Specification No. RDSO/SPN/TC-104/2015 Rev.-0 for the system has been finalised & issued.

· Product development is being explored with one firm.

Informal Item

Item No. : 2.7 Subject : RDSO/SPN/TC/103/2013 for (Ethernet to Optical) Media converter The specification covers the specification of Managed media converter. The purpose of Media converter is to convert Ethernet to Optical signal and vice versa for transport of Ethernet frames over optical fiber cable. Typical use case is shown in the diagrams below.

The main features are:

i. PoE on user ports for powering the devices like IP phones. ii. Two Gigabit network side ports (combo ports) which can be connected to copper

and or OFC by plugging in SFPs (optical transceiver). iii. SFPs can be chosen to get a range of working of 40 km on a pair of fiber or a

range of working of 10 km on a pair of fiber or on single fiber. iv. Interoperable with CISCO switch and router on fiber connectivity. v. All the features of layer 2 switch. Can be used as layer 2 switch also.

vi. SNMP based management for remote configuration and monitoring. vii. Wide power supply options

a. AC 100 V to 240 V AC


b. 36 to 60 V DC c. 99 to 132 VDC.


Comments from WR I. RDSO/ SPN/ TC/ 103/ 2013, in this specification Clause 2.2.4, the last sentence is to

be replaced as ‘The Traffic shall be automatically diverted to the other ports. RDSO’s Remarks: The existing clause ‘the traffic shall be diverted to the other port’ is for automatic diversion only. That will be ensured while testing of the device. Whenever next amendment or revision is issued, this will be made explicit by including the word “automatically”.

II. The specification is basically for managed switches having 4 Ethernet ports and 2

Compo ports SFP in the uplink side. It scores over simple media convertor by provision of media diversity between two WAN Ports / both ends. However, this product is likely to be much costlier than simple ‘media convertor’ and by naming this specification as media convertor; RDSO may restrict the option of the purchaser of buying simple media convertor. The functionality achieved through the proposed product can also be achieved by using two managed switches at both end connecting two pair of media convertors between the WAN Ports of the switches. RDSO’s Remarks: Requirement was for managed media converter, and all managed media converters come with many features which are generally available in layer 2 switches.

III. For many applications, the media diversity may not be required and the over

specification may results in costly product in the similar way as was the case with switch with all ports is specified as power on Ethernet. It is suggested to rename the product. RDSO’s Remarks: It offers great advantage by way of providing increased availablilty. Also availability of two SFP ports make it’s use very flexible. It can be used in ring configuration. There is already separate RDSO specification for switch. It is designed as Media converter by having very precise definitions of SFPs.

Comments from NWR


Media converter shall be designed so that it can be directly mounted on RJ-45 Ethernet port and shall be driven from power of device to which it is connected. It will save upon additional power supply to media converter. RDSO’s remarks: The present specification being for managed media converter, it’s power supply requirement can not be met with PoE. This media converter itself has PoE feature on two of its ports. SER’s comments: Item is commercially available off the shelf product. Moreover, features specification are rapidly changing as per technology development. Therefore no need to retain the specification. RDSO’s comments: The specification was framed as per recommendations of 37th TCSC.One vendor has applied for vendor registration also. It can be reviewed whenever any major technological change takes place. Summary of Discussion: Shri Yashpal Singh Tomar, Director/Telecom III & secretary explained the features managed media converter as per specification RDSO/SPN/TC/103/2013. The comments received from various railways were discussed. It was suggested that since, it has features of switch also, its name may be changed. It was mentioned that managed media converters generally have switch feature and this product is available under the name managed media converter.It was suggested that the name of the product may be changed to indicate that it has feature of layer 2 switches also.

Need of a media converter without features of switch and for purpose of just converting Ethernet to optical and back was also underlined by NWR. Recommendation of the Committee:

38th TCSC recommends implementation of specification of managed media converter as per specification RDSO/SPN/TC/103/2013 as agreed during 37th TCSC. The name of the device may be changed to “Managed Media Converter with Ethernet switch”.

New specification of Media converter (Unmanaged) may also be issued separately.

Item No. : 3.1 Subject : Specification No. IRS: TC-55-2006 Amendment 2.0 for 24 Fibre

Underground Armoured Optical Fibre cable. File Ref. : STT/OFC/Misc./623 Vol. I to XV Agenda : To consider amendment of the specification for 24 Fibre

Armoured Optical Fibre cable for upgrade to 48 Fibres in place of 24 Fibres.

Notes by Secretary:

RDSO has initially issued specification vide specification no. IRS: TC-55/1991 in year 1991. Based on the above specification, Zonal Railways started implementation of Optical Fibre Communication Network on Indian Railway.

RDSO initially issued specification for armoured underground optical fibre cable

consisting of optical & mechanical parameters of Optical Fibre cable, its test procedures, methods and parameters. This specification provides initially 8 / 12 fibres for communication.

Railway Board vide letter no. 94/RE/141/7, dtd. 09.01.1996 directed that Railway

should go in for 18 fibres optical fibre cable in future. Subsequently revised specification for optical fibre cable for 18 / 24 fibre has been issued in 1996 vide IRS: TC-55/1996 by RDSO.

Subsequently capacity of optical fibre cable has been increased to 24 Fibres and

made standard size for Indian Railways with distributed 6 loose tubes for Fibres. In addition to this, to cater the need of IR termite protection has also been included and revised specification was issued in year 2000 vide spec. no. IRS:TC-55-2000. Subsequently during period from year 2000 to 2005 three amendments were issued by RDSO.

Meetings were conducted with all the manufacturers on specification IRS: TC-55-

2000 and based on the recommendation of 33rd TCSC in year 2006, revised specification of OFC vide spec no. IRS: TC-55-2006 was issued on 1.5.2006.


Subsequently amendment no 1.1 to the above specification was issued in year 2007. Based upon the recommendation of 36th TCSC, amendment 2.0 were carried out for the specification in year 2012 which is currently in vogue.

Provision of 48 fibres in the existing OFC does not require any constructional

change in the cable. Only numbers of fibres shall be increased to 8 fibres per loose tube in place of 4 fibres per loose tube keeping no. of loose tubes same as 6.

In recent past it is observed that Railtel is also procuring 48 fibre armoured OFC for

their application IR territory. Railways are also feeling short of dark fibres as more no. of applications are coming in requiring more numbers of fibres.

In view of the above, it is proposed that Specification No. IRS: TC-55-2006

Amendment 2.0 for 24 Fibre Underground Armoured Cable may be amended for 48 Fibre OFC in place of 24 Fibre OFC against same IRS specification. Railways Comments and RDSO Views: SN Zonal Railway Comments RDSO’s View

Comments from Railways: Comments from WR

a) The write up talks ‘about emergency 2 way communication between Loco Pilot and concerned Control Office’. There is clarity about the media to be used for this two way communication. Is it only different name for the existing VHF communication or a separate Radio Trunk will be built through GSMR. RDSO’s Remarks: It is based on satellite communication.

b) Similarly nothing is written about the network which will be used for unusual incidence reporting or in SOS messages. RDSO’s Remarks: It is via satellite communication.

c) With most of the equipments to be installed in the Locos, the maintenance responsibilities need to be clearly defined before the project is given a trust. RDSO’s Remarks: Noted.


Summary of Discussion: Shri Yashpal Singh Tomar, Director/Telecom III & secretary explained the features of the ongoing project with Space Application Center Ahmedabad. Concern regarding non-availability of S-band spectrum was raised. RDSO observed that once the system capabilities are demonstrated, strong case can be made for S-band spectrum for the system. Association of ISRO with the project can also help in getting the spectrum. Recommendation of the Committee:

38th TCSC recommends to continue with the development of the system with SAC ISRO for demonstration of the capabilities of system.

Item No. : 3.2 Subject : On going and new projects:

· Field Trial of VoIP based TCCS.

1. Background:

Specification of VoIP based Train traffic control communication system (TCCS) have been finalized by RDSO. The specification contains the scheme of the system and functional and technical requirements of the system and its various components. Since this system is for vital communication for train operation, field trial was considered necessary to evaluate the system and to take the feedback of the user. Therefore a work for field trial of VoIP based TCCS has been sanctioned in RDSO. The field trial would be done in a small section of 12 stations. The section is Mau- Shahganj traffic control section in Varanasi Division. The contract for this field trial of VoIP based train control communication as per RDSO/ SPN/TC/99/2012 Rev. 1 to has been awarded to M/s Bitcom. The scope of the contract includes supply of data networking equipments also, in addition to VoIP based TCCS components, for setting up the network. As per the requirement of the contract, the firm demonstrated various features of the proposed solution in a lab setup in RDSO.

2. Set up for demonstration: The set up consisted of following

Ø Section controllers- Two numbers. For trial, one of the controller’s equipment was implemented on lap top.

Ø Emergency controller- Implemented on lap top. Ø Way stations - 4 Numbers (station A, B, C, D): SIP telephones were provided

for each way station. Ø Voice logger as per existing RDSO specification with gateway to enable

recording in the existing voice logger. Ø New voice logger as per specification of VoIP based TCCS. Ø Gateway for emergency control Ø Communication server Ø FXS gateway Ø FXO gateway


· The schematic of the setup is given in the diagram below.

3. Possibilities: In addition to features mentioned in RDSO specification, the following possibilities also exists which can be implemented over SIP based solution: · Instant messaging between various subscriber. ASMs, controller may

interchange information through messages instead of making a voice call. This could be used by ASMs to give train position to the Section controller, thereby reducing the volume of call traffic and workload on section controller.

· Emergency broad cast messages to a pre-defined group on their mobile telephones through GSM gateways.

· By installing client software, mobile telephones could also be used as control telephones.

· PA system of a particular station can be selected from control office and centralized announcement can be made.

· VHF gateways can be provided at way stations. This will enable using stations VHF radio from the control office to make conversation with driver/ guard.

· Controllers console can be used to make call on mobile telephones also through GSM gate way. Making calls on mobile network in place of using mobile can offer many advantages, e.g.


Ø Availability of call log Ø Possibility to record the conversation Ø Antenna of GSM gateway can be placed at a location to enable

better connectivity. Ø Conferencing with way stations

Out of these possibilities, vendor will try to demonstrate some of these during field trials itself. These could be added in the next version of RDSO specifications:

Comments from Zonal railways

Comments from WR

(a) Western Railway is going ahead with the installation of equipment based on RDSO Specification in BRC Division.

RDSO’s Remarks: The specification was issued for trial purpose. Based on the result of the trial, the updated version of spec will be issued.

(b) RDSO specification for IP based control phone should include interface for SCADA also.

RDSO’s Remarks: The VoIP based control communication does not include SCADA. However once IP network is in place in a particular section for VoIP based train control, the same IP network can be used for connecting IP based SCADA device also. The only remaining problem would be IP connectivity from OFC hut to SCADA locations like SP, SSP etc.

1.1 Control office: 1.1.1. Two controllers, section Controller 1 and Section Controller 2 (Consoles for controller)

All servers, controllers, Recorders, Gateways switches, Network paths and way station phones to be duplicated and be kept in hot-standby mode.

Communication Servers are duplicated. Possibility of gateways, recorders and Way station will be examined keeping in view implication on cost. IP network design is not is scope of this spec.



RDSO’s Reamark

2. Various features: 2.1 Controller makes a call to Way Station A. Controllers console shows that currently station A is talking to controller.

All stations should be geographically represented on the controllers console and probably on way station console also.

Try to accommodate to the extent possible within the available touch screen space of console.

2.2 Controller calls way station B also while the call with A continuing, way station B gets added to the ongoing call between controller and a station A and a conference call starts. Now the console shows SC (Section Controller. Station A and Station B are in a conference.

All communicating way stations etc. should just be indicated in a colour earmarked for conference (preferably-green).

Yes. It is provided.

2.11 Only one control telephone will be provided for ASM. He will be able to call any other controller and will be receive call from any other controller.

One top priority phone i.e. section control should be separate from other control phone and in case of failure of one phone the other should take over its functions.

Ok. This will be implemented.

2.14 The system has a separate recording device for recording conference conversations of various controllers. The feature of recording way-station to way station conversation not involving controller can also be enabled. However it will consume bandwidth of the channel from way station to HQ station.

Recording way-station to way station conversation not involving controller should be permanently enabled like in existing analog multi-channel voice logger as per RDSO Spec RDSO/SPN/TC/38-02. However a suitable gateway shall be provided for this purpose in this system.

OK.



RDSO’s Reamark

2.18 If a certain group of way station lose connectivity with the server, they can still make one to one call with each other. This feature was demonstrated by directly entering the IP of the way station required to be called.

Entering the IP of the way station should be replaced with the standard short name code of the station. It will be convenient for user i.e. ASM.

OK. It will be implemented.

3.2 ASM should get call waiting indication when any other controller try to call him (other than his section controller) when he (ASM) is on another call.

ASM should get call waiting indication when any other controller try to call him (other than his section controller) when he (ASM) is on another call through faint beep & console indication.

When other controllers calls ASM, they will get connected to on going call of ASM.

3.3 If any ASM’s phone is disconnected from VoIP network, then controller’s console should show out of order indication for that particular ASM.

If any ASM’s phone is disconnected from VoIP network, then controller’s console should show out of order indication for that particular ASM with colour code (red).

Yes It is planned like this.

3.4 When any station gets connected to on-going conference with section controller, an audio indication of beep at section controller side may be given.

When any station gets connected to on-going conference with section controller, an audio indication beep at section controller side may be given. The volume of the beep should be lower in order not to mask the spoken word of the conversation.

Yes. This will be implemented.

Suggestions: 1)

on one communication server.

Emergency communication circuit quad should not be cut anywhere and should be fed with Emergency control voice signal in phase at every station. This will ensure uninterrupted Emergency communication in case of one cable cut in block section.

The feasibility of this shall be examined during trial.

Summary of Discussion: Shri Yashpal Singh Tomar, Director/Telecom III & secretary explained the details of field trial being done in Mau- Shahganj section of NE Railway. Feature of Single common phone for the use of ASM was also discussed. Members were of the view that in addition to common phone for ASM, separate telephone instruments must be provided for simultaneous access to controllers by staff of respective departments. Additional possibilities which are not part of existing specifications were also developed. It was noted that the system should be developed so as to be ready for phasing out TDM technology based MUX. NWR noted that such elaborate system is not needed and readily available solutions like NetMeeting can be used for this purpose. RDSO observed that it was ready to examine such solutions and requested to NWR to give the details. Issue of interoperability of SIP telephones of various vendors with the system was also raised. RDSO observed that SIP phone of different vendors are likely to be interoperable. However features of VoIP based TCCS which are not supported by SIP may not be available if telephone instruments of different vendors are used. This aspect would be discussed and examined during the course of the trial. RDSO also mentioned that all the suggestions given by SECR will be examined for implementation during trial and incorporation in new version of specification whenever it is issued. Recommendation of the Committee: 38th TCSC recommends to carry out the proposed trial and examine following;

1. Interoperability of SIP phone of different vendor with the VoIP system. 2. Suggestions given by SECR. 3. RDSO to obtain and examine the suggestions of NWR regarding readily

available solutions like NetMeeting for this purpose.

Item No. : 3.5 Subject : Use of cable termination above ground, instead of under-ground cable jointing for 4/6 quad underground telecom cable Use of cable termination above ground, instead of under-ground cable jointing for 4/6 quad underground telecom cable. This will offer following advantages

1. Easy localization of joint location. 2. Easy to isolate faulty section. 3. Problems caused by bad quality of jointing can be eliminated.

Disadvantage may be possibility of out side interference. This issue needs deliberation during TCSC to arrive at a decision. Summary of Discussion: Shri Yashpal Singh Tomar, Director/Telecom III & secretary explained pros and cons of the proposal. The various points came up during discussion;

1. The termination may get submerged during water logging. 2. Quality of and type of termination will be very important. 3. Effect of keeping underground joint above ground need to be examined. 4. Arrangement for derivation joint and mounting of EC socket need to be

examined. 5. Chairman TCSC mentioned that the quad cable is designed for

underground use and therefore joints should normally be underground only. It was decide that the zonal railways may be asked to give their view on this proposal and trial may be done in few sections before arriving at final decision. Recommendation of the Committee: 38TH TCSC recommends that the zonal railways may be asked to give their view on this proposal and trial may be done in few sections before arriving at final decision. Railways may also give their views on the following points;

1. The termination may get submerged during water logging. 2. Quality of and type of termination will be very important. 3. Arrangement for derivation joint and mounting of EC socket need to be

examined. RDSO may also examine effect of keeping underground joint above ground.


Additional Items suggested by various zonal railways

Items from CR

1) Set up of a study group on Railnet VPN and local Network architecture for Zonal Railways, Divisional set ups towards operating all IP based services except UTS/PRS and FOIS from Railnet VPN. Release of standard network architecture design including deployment of DSLAM for access network and implementation documentation from RDSO.

RDSO’s Remarks: To be discussed in meeting Recommendations of TCSC: A committee of CCE/CR, CCE/WCR and CCE/NWR to be formed with CCE/CR as its convener.

2) Networking of Data-loggers through Railnet IP network

RDSO’s Remarks: At way stations, E1 connectivity is available. For easy deployment of IP based devices at way stations, Ethernet connectivity should be made available. One section may be taken up for trial purpose for deployment of such devices. A report was submitted by RDSO regarding possible replacement of SDH equimnets by suitable packet data transport network technology. Summary of Discussion: It was noted that at present data logger is not IP based device. The decision in this regards is to be taken by Signaling directorate of RDSO. However there is need for migration from E1 based SDH network to Ethernet based network. The committee proposed against item 1 above may suggest road map for such migration. Recommendations of TCSC: There is need for migration from E1 based SDH network to Ethernet based network. The committee proposed against item 1 above (committee of CCE/CR, CCE/WCR and CCE/NWR with CCE/CR as its convener) may suggest road map for such migration.

3) Cross-connect Cabinets for OFC Huts and structured cabling:

RDSO’s Remarks: To be discussed in meeting. TEC spec for cross connect is available, therefore separate RDSO specification may not be required. Also, unless there is big market, vendors would not normally come for vendor registration against Railway specific requirement.

4) Standardisation of Brick Masonary construction of OFC Huts:


RDSO’s Remark: The drawing already available as drg No RDSO/TCDO/COP-1 Building layout for Fiber optic hut.

5) Use of STM-4 for junction stations in S/H Networks:

RDSO’s Remarks: Can be decided based on the requirements of specific station. TCSC’s recommendation:Can be decided based on the requirements of specific station.

6) Revision of PD-Mux specs to ensure Interoperability of PD Muxes at E-1 level and masking of management bits at E1 interfaces and E-1 branching ports for PD Muxes.

RDSO’s Remarks: At present there are two main suppliers of MUX, M/s Webfil and M/s PUNCOM. Interoperability has not been insisted upon since the beginning of the development of this MUX. The present version is based on 2004 RDSO specification. If we enforce interoperability, the MUXes will not be backward compatible with the existing versions of MUX. It is better to plan same make of MUX in one section/ link. TCSC’s recommendation: Mux as a technology is likely to be phased out. There is no need for new development in this product.

7) TSF-2 jointing kits for Qd cables :

RDSO’s Remarks: Existing universal type jointing kit for quad cable can be used for all types of joints, straight and derivation joints. This simplifies inventory management. TCSC’s recommendation: Zonal railways view may be taken on this issue.

8) Alternative to Byte type phones:

RDSO’s Remarks: Zonal Railways may share their experience and suggest. As per Railway board policy open standard based IP PBX using SIP, to be provided. TCSC’s recommendation: Railway Board will ask BYTE regarding continuation for support. As per new policy of Railway board, open standards based IP exchanges based on SIP protocol may be considered. However, while going for IP telephones, the powering of IP telephone must be planned carefully.

9) Code of Practice Telecom earthings:


SER also suggested RDSO specification for earthing of Telecom equipment is required. RDSO’s Remarks: Issue of earthing and bonding for telecom is part of report submitted to Railway board by Working group on Surge protection and earthing of Signal and telecom equipments. Details on erathing and bonding of telecom equipments are also available in the report. If agreed, the relevant portion shall be circulated to zonal railways and issued after examining the suggestions of Zonal Railways. .

10) Code of practice for Fire alarm and detection systems for Telecom installations. RDSO’s Remarks: Signal directorate is finalising specification for fire detection and alarm system. The code of practice for telecom installation can be based on the same specification. TCSC’s recommendations: The code of practice for telecom installation should be based on the specification being finalized by Signal directorate of RDSO.

11) High Through Put LAN Extenders RDSO’s Comment: RDSO has issued specification for (n x 64 Kbps) LAN Extender which caters the speed of up to 2 Mbps with 4 LAN ports. The stipulated speed of LAN Extenders is sufficient for data application like UTS/PRS & FOIS. However, CCE/Central Railway suggested High Through put LAN Extenders with speed of 10 Mbps up to distance of 1.0 Km, whereas present specification caters speed of 2 Mbps up to distance of 5 Km. & 10 Km. at 64 Kbps speed. As per prevailing technology of modulation as we increase the speed the coverage distance is reduced.


Comments from ECoR 1. Reputed make (3-4 makes) of vital items like servers, storage device etc. and

associated softwares need to be defined by RDSO to ensure quality. RDSO’s Remarks:

(i) RDSO has issued generic specification to suit the Railway’s field requirement and site conditions for cameras &softwares. Technical parameters are provided to ensure the quality of material. Since manufacturing and testing facilities of these equipments are not available in the country. Railway Board has issued guidelines to carry out 3rd party inspection on the ISS equipment (cameras & software in this case) at OEM premises against awarded contract with other stipulation like additional 10% BG on items inspected abroad to ensure the quality.

(ii) Since servers & storage device is commercially available off-the shelf product, however 5 nos. reputed international makes are specified for servers and 7 nos. reputed international makes are stipulated for storage device in the specification.

2. Associated account is insisting for procurement of materials through Stores and

execution of works through contract. This may cause compatibility issue of various equipments besides difficulty in planning and execution due to different lead times of various equipments. Therefore, guidelines regarding procurement and execution need to be issued by Railway Board.

3. RDSO was requested to finalize RDSO Spec. of IP Based VSS- RDSO/SPN/TC/65/2015, Rev 3.0 at the earliest. As there is no Approved list of Vendors for VSS, it was also requested to look into the feasibility to circulate list of reputed makes with versions (3-4 makes) of its vital constituents like Camera, Servers, Switches, Storage devices and associated software etc. for guidance of Railways.

4. In some Railways, Finance is insisting for procurement of material through Stores and execution of works through contract which may not be practically viable due to compatibility requirement among various sophisticated equipments. Therefore, guidelines regarding execution are desirable which may include criteria for ‘similar nature of work’ also as VSS is integration of various sophisticated equipments at site. RB vide letter No.2014/TG-IV/16/SAN/24/CCTV dtd.14.9.2014 has instructed to use CCTV cameras installed under ISS or otherwise to be utilized for monitoring cleanliness. Therefore, provision of additional monitoring arrangement at Chief Health Inspector’s office is also required to be included in the estimate which is presently not catered in RB’s unit Abstract estimate.


RDSO’s Comment: Revision 3.0 to the specification of IP based video surveillance system is being carried out by RDSO. Since there is no approved or preferred make of Cameras and software make and RDSO is only carrying out inspection on the product to ensure compliance to the specification therefore makes are not circulated. Item 2 and 4 does not pertain to RDSO.. 5. AMC of IPDSLAM Switches.

Railway Board vide letter No. 2006/Tele/RCIL/4 dated 15.05.2015 has instructed to all Zonal Railways to take over the O&M of IPDSLAM with immediate effect which are under warranty upto 26.06.2016 and NMS of IPDSLAM will Continue with RCIL for centralized monitoring. Following issues need to be deliberated in this regard-

( i ) Configuration set up of Secure Caching Gateway system and IPDSLAM Switches has not been shared by RCIL to Zonal Railways. While inviting the tender for AMC of IPDSLAM Switches, configuration set up will be required.

(ii) As the equipments are of propriety nature with less volume, it may be difficult to get suitable agency through open tender for Zonal Railways.

( iii ) Presently the system is under warranty upto 26.06.2016, but RCIL is not co-ordinating for replacement/ rectification of defective modules of IPDSLAM switches of Zonal Headquarter, Bhubaneswar, as observed during last failure in Julty’15 when no. of modules became faulty. Railway co-ordinated directly with OEM with lot of difficulty as contract is between RCIL & HCL. As Railway is the sufferer, clear cut responsibility with provision of penalty on RCIL for delay may be issued for maintenance during warranty.

In view of Para (i) & (ii), it is proposed that AMC of Hardware & Software provided in Zonal Railways may also be dealt by RCIL alongwith NMS as being done for last 3 years with suitable penalty clause for delay in rectification.

Remarks: This is out of purview of TCSC. 6. Codal life of Telecom & IT Equipments.

Codal life of new assets like CCTV Camera, Network storage devices, Digital Photocopier machines etc need to be defined. In view of fast changing technology, codal life of existing electronic/software based equipments also need to be reviewed. Also


codal life may be specified in specific years and not in range of years for clarity in planning for replacement.”

SR has also raised this issue as follows; “Codal life of Telecom assets- The codal life of Telephone exchange is 12 to 15 years. Since frequent updations in OEMs software versions and compatibility issues with other exchanges (Next Generation Network) the codal life may be revised and reduced to 8 to 10 years for major exchanges (12 to 15 years for other small exchanges). The codal life of other telecom items like walkie talkie, (FC, equipments are to be reviewed.”

RDSO’s Comments:CCTV cameras, Network Storage Devices etc. are product recently introduced in Railways for IP based Video Surveillance cameras, more experience in functioning of these equipment need to be gained. Digital photocopier machines etc. are not dealt by Telecom Directorate of RDSO. Therefore, codal life of these equipments may be stipulated by C&IS Directorate. Moreover, codal life of all products is being issued by Railway Board. Based on the experience of the zonal railways, this can be reviewed for specific items. The deciding parameters may be, performance degradation, obsolescence (Non availability of spare parts etc), compatibility issues RDSO’s view on the suggestion: (i) CCTV cameras, Network Storage Devices etc. are product recently introduced in Railways for IP based Video Surveillance cameras, more experience in functioning of these equipments need to be gained. Digital photocopier machines etc. are not dealt by Telecom Directorate of RDSO. Therefore, codal life of these equipments may be stipulated by C&IS Directorate. (ii) Based on the experience of the zonal railways, this can be reviewed for specific items. The deciding parameters may be performance degradation, obsolescence (Non availability of spare parts etc.) and compatibility issues.


Comments from NCR 1. Dis-continuing Emergency Sockets. The practice of emergency sockets at every kilometer was to provide communication in the mid-section when present means of communication like MTRC and GSM mobile were not available. Now public mobile network covers a large area of railway track. It is being provided to train crew also therefore the necessity of continuing with emergency sockets is no more required and also it is rarely used. It is also mentioned that MTRC is gradually being introduced and to begin with the practice of emergency sockets it is proposed by discontinued in MTRC section. RDSO’s view on the suggestion: This is a policy related issue and does not pertain to RDSO. 2. Provision of MTRC handsets instead of walkie-talkie sets. MTRC mobile sets are being procured for providing to Guard and drivers of the trains in MTRC section of New Delhi- Jhansi which is also being extended up to Bina. In addition to this Walkie-Talkie sets are also being given. In MTJ – PWL automatic signaling section during fog, MTRC is used by Loco Pilot and Station Master in train working when modified automatic working is introduced. Thus MTRC has established as a more reliable communication system than walkie-talkie sets and providing walkie-talkie in MTRC section has become redundant. Therefore, it is proposed that the use of walkie-talkie sets for the loco pilots and guard in MTRC section be discontinued. RDSO’s Comment: MTRC system based on GSM-R system has been provided between New Delhi – Jhansi on NCR. Another work is sanctioned between Jhansi – Bina –Nagpur section on NCR, WCR & CR. GSM-R system is train radio communication system between Driver – Guard – Station Master & Controller on GSM handset with customized applications for Railway specific use and environmental condition. CSTE/NCR has suggested that MTRC system has been made functional between New Delhi – Jhansi section and walkie-talkie set is no longer required as GSM-R handsets have been given to train drivers, guards and station master. Issuance of such guidelines is under jurisdiction of Railway Board.


RDSO’s view on the suggestion: This is a policy related issue and does not pertain to RDSO. 3. Standard equipment of ART removal of WLL exchange-

WLL exchange is a part of the ART equipment but it is not provided and its availability is also limited. With the development of other communication means like GSM mobile and MTRC need of WLL exchange is not necessary. Therefore it is proposed that standard list of ART equipment be reviewed and WLL exchange few removed from the standard list. RDSO’s remark: WLL exchange can be removed from the standard list.


Comments From NER

1. Material of RDSO approved firms: There should be similarities and compatibility in material of RDSO approved firms. So that the equipments of different make and model can be used in combination. The performance of firms may be decided on the basis of feedback of equipments installed in Divisions/zones RDSO’s Remarks: As far as possible, specifications are made for compatible and interoperable equipments. The performance of the firms is decided on the basis of On Line complaints received.

2. RDSO Specification for 5W VHF Set: RDSO specification for 5W MIL std VHF set , its battery and battery charger are not available. RDSO may be requested to provide specification along with approved vendors. RDSO Specification for 25W VHF Set: RDSO specification for 25W VHF transceiver set along with its accessories available. RDSO may be requested to provide specification along with approved vendors. SECR also commented as follow “Previously 5 Watt/25 Watt VHF sets were procured as per DGS&D rate contract based on DGS&D specification, but after the year 2010 there is no DGS&D rate contract. So, it is essentially required.” RDSO’s Remark: Noted, proposal for development of 5 Watt/25 Watt VHF sets already sent to Railway Board. Spec may be developed if permitted by Railway Board.


3. Comments from NWR

1. Multiplexer-MUX (Primary and Drop insert) as well as STM specification need to be modified to make provision for cards for data connectivity for possible communication protocol and all possible means namely optical fiber / cable / Wi-fi so as to provide connectivity to router of Railnet/UTN, directly on the port without any additional modem / protocol converter

RDSO’s Remarks: RDSO does not have STM’s specification. STM’s being procured as per TEC GR. The present TEC specification support Ethernet connectivity which is the most common WAN port on routers.

It is not advisable to modify specification of existing primary Multiplexer as it would disturb backward compatibility.However a new specification can be issued for a device with various interfaces on user side and on network side. This device could be used for extension of connectivity of various types at sites along the track.

2. Specification of VSAT for uplinking streaming video from ARTs needs to be reviewed as advised by this office letter No. SG40/I/Vol-II dated 23.11.11 (Copy enclosed) RDSO’s Remarks: The specifications of portable manual setting type VSAT and associated accident site communication equipments were issued for one time procurement. When-ever next procurement is planned, the specification shall be reviewed based on availability of equipment in market.

3. HDPE pipe for OFC laid over ground is not fire retardant which is frequently causing damage, due to fire in the accumulated garbage. It needs to be replaced by specially treated “Chlorinated polyvinyl Chloride” pipes akin to “Blazemaster®” for over ground cable laying.

RDSO’s Comment: As per RDSO specification for Permanently Lubricated HDPE duct for optical bre cable, fire retardancy feature has been provided in the specification. However, HDPE duct and optical fibre cables are meant for underground laying. Method of over ground laying of optical fibre needs to be deliberated in the meeting.

RDSO’s views on the suggestion:

As per RDSO specification for Permanently Lubricated HDPE duct for optical fibre cable, fire retardancy feature has already been provided in the specification.


Comments from SR

I. Performance of V-SAT

1. The camera is not provided with view finder. It is difficult to capture quality video properly. RDSO’s Remarks: In the new specification Camera with view finder provided.

2. Video is freezing frequently: RDSO’s Remarks: The VSAT can support data rate up-to 512 kbps. Problem is required to be isolated, whether related to satellite link, or data network problem or any configuration problem.

3. The length of the cable is limited to 5 metres and very difficult to connect camera from disaster site. RDSO’s Remarks: In the new specification camera transmits on wireless.

4. Assembling of antenna is very difficult and consumes more time duration for provision of V-Sat during crises period. RDSO’s Remarks: Being manual setting type, it is expected to take more time. However, we can find out time taken by other units in setting up to find out if unusually long time is being taken up by a particular unit.

III. In the present situation, the compatibility problem between major exchanges exists. It is requested to standardize the specification for procurement Exchanges under two categories-

Category 1: Standardisation of specifications for major Exchange available at Zonal HQ & Divl HQ.

Category II: Small/medium exchanges installed at other locations.

RDSO’s Comments: The guidelines for standardizing voice network including IP Exchanges is contained in Railway board’s Telecom Circular No 12/2012. This circular is issued under letter No. 2010/Tele/9(3) dated 12/09/2012. The main points are:

· Asterisk an open source telephony software should be used for IP Telephony. · RDSO should issue guidelines for its implementation (Report by RDSO is

available on RDSO website http://10.11.2.19) · These guidelines modified on 15.12.2015, to include Open standards based IP

exchanges in place of open source Asterisk based exchange. · As per new Guidelines, RDSO is required to issue guidelines for implementation

of IP telephony. IV. AMC/ARC for all Telecom items.

RDSO’s Remarks: Any problem in entering AMC/ARC can be discussed for specific items.


Comments from SER 1. Likely RDSO approved source of supplier for LAN Extender, 2 Mbps Modem, 64

/ 128 Kbps Modem need to be disconnected.

At the time of procurement, it has been found that RDSO approved single vendor quotes very high rates. In the market, price is quite low as these type of materials are readily available in the market with very low cost.

RDSO’s Comment: RDSO has issued specification for above datacom equipments for last mile connectivity to critical applications like UTS, PRS & FOIS. There are various test parameters which have been provided in specification that ensures good quality of equipment. Provision of tests which ensures compliance the RDSO specification add up certain cost to the equipment. These equipments are supplied with specified inspection process which ensures the continuance of same quality and conformance to the specification of supplied item. Moreover value addition like field upgradable interface modules have been incorporated in the specification. Items available in free market are mostly cheap imported product from China without any quality control. Without good quality equipment, it will be very difficult for maintenance organization to ensure the high availability of critical applications like PRS / UTS & FOIS.

2. The specification of CCTV camera should be simplified so that more numbers of vendors can participate. The current specification of cameras are not available in India. It is imported from abroad.

The cost of CCTV cameras of RDSO specification are very high (Rs. 1,21,000/- for P/T/Z and Fixed Box Camera at Rs. 38,500/-) and are imported. The repairing time is also lengthy. But non-RDSO specification cameras are cheaper and readily available in market.

RDSO’s Comment: RDSO specification stipulated the parameters of best available product in the industry because the field condition of Railways are quite different and stringent as compared to CCTV applications in other part of market like malls, shopping complex, etc. The specification was drawn after study of various similar area like airports. Specification is also based upon the document submitted by security directorate of Railway Board. Mostly CCTV cameras are manufactured outside India and this is market driven business model and RDSO has prepared the specification to procure products which are available in the market.


Moreover as per the data available from inspections carried out, there were 5 numbers of OEMs of cameras have got the contract and got their item inspected by RDSO and supplied to zonal Railways. These OEMs are Samsung, Infinova, DVTEL, Indigovision&Hikvision.

RDSO’s views on the suggestion:

Comments from WR

1. Satellite Communication in the ART:- So called Briefcase type VSAT Terminal which is supplied to ART actually comes in several large boxes and needs at least a couple of hours to set up even when ART is standing in the yard. The temporary trolley which is provided is totally unsuitable for carrying boxes over the ballast uneven road or even on embankment. A simple power supply unit and direct connections need to be provided whereby at least satellite phone can be set up within 30 minutes by carting the material on the back packs of not more than two persons.

RDSO’s Remarks: The purpose of the system is to do video streaming from the site. The specification was framed taking into account all possible scenarios. Therefore both AC and DC power supplies with battery back up are included. Also 3 wi-fi access points are included to cover larger area. Spare batteries for all wi-fi access points and video modem are included to maintain uninterrupted service from site. Being designed for disaster site, it was made sturdy and capable of working even in presence of minor rain. Since these equipments are to kept and transported by ART, the packaging is also suitable for such use. All these factors led to increase in weight. However all the components are not necessarily to be un-loaded at site. To futher simplify handling and operation going for road vehicle mounted devices can be considered.

2. Railway Board may again approach DoT for authorization of the issue of BGAN terminal on the lines of the terminals issued to NDRF without waiting for BSNL gateway to set up in India, which is getting delay.

RDSO’s Remarks:Not in purview of RDSO. 3. With the backbone migrating on carrier Ethernet / PTN, it should be legislated by Railway Board that all applications including the one listed below should now be exclusively TCP/IP based: (i) Data logger for signaling. (ii) TMS / Train Describer Communication. (iii) SCADA RDSO’s Remarks: Most of IP based device have Ethernet interface. Therefore Carrier Ethernet access device are required at way stations also so that these and other IP based applications can be supported easily. Further during TCSC meeting,for similar issue, a committee of CCEs is already proposed in this TCSC meeting.


4. All applications are have been recently developed by CRIS (e.g. IPASS) and the applications under development, which are primarily meant for internal use, should be so deployed that they primarily used Railnet connectivity, the Internet connectivity should only be secondary option. RDSO’s Remark:Does not pertain to RDSO. Guidelines for Railnet Network issued vide letter NO. 2000/Tele/1/Railnet work Pt dated 30.04.2007 should be followed to strengthen the network.


Comments from WCR

1. Instead of approving specifications, RDSO to approve telecom products In the fast changing world of telecom the rate of obsolescence is rapid. In such a scenario, the conventional model of developing generic specifications and approval of vendors does not deliver the results as desired because, by the time specification is finalized and vendors are developed, better products are available in the market. To eliminate this problem, RDSO should develop Functional level specification (FLS) only and directly approve products for each application. RDSO’s Comments: This issue needs to be examined in detail to work out such procedure and to shortlist such items. It will also require approval at appropriate levels as it is not covered under present procedures. The following issues may be required to be addressed a. Quality issues b. Testing of some functional requirement may not be possible. c. Ensuring long term support would be difficult d. Filtering out so called cheap Chinese product would be difficult.

2. TEC specifications to be adopted by Railway wherever available TEC has developed specification and approved vendors for a large number of telecom equipment. Instead reframing the specification afresh and approving fresh vendors, it would be better if, Railways directly adopt TEC specifications and procure equipments from TEC approved vendors. This will reduce a lot of redundant work and save huge amount of time. RDSO’s Comments: This is already existing and there is policy of RDSO’s inspection also for such items. Policy for inspection of items as per TEC specs: Railway Board’s Letter No. 2006/Tele/TC/1 dated - 17/04/2006 and dated – 09/01/2008 stipulates following guidelines for inspection of Telecommunication items:- ii. All the materials with TEC/BSNL specification and procured from TEC/BSNL approved firms (approved for bulk supply and not as interface approval) shall also be inspected by RDSO provided the cost of the material is more than Rs 1 lakh. iii. All the materials with TEC/BSNL specification and procured from sources not approved by TEC/BSNL (including firms having only interface approval) shall also be inspected by RDSO provided the cost of the material is over Rs. 5 lakhs. However, in such cases RDSO shall carry out prototype approval before taking


up regular inspection.

3. Approval of telecom equipment for communication based Signaling RDSO to approve equipment for communication based signaling including media converters, protocol converters, Multiplexers, multi level access platform etc. Already some pilot projects have been done on some Railways like IBS working on OFC. RDSO’s Comments: This issue pertains to Signal Directorate. Telecom directorate will provide necessary assistance on specific requirement of signal directorate.


Comments from IRISET, Secunderabad

1. On Culverts/Bridges built with RCC slab & provided with ballast retaining wall a provision for cable duct of proper size to run OFC Quad Signal cable should be made in the design/drawing of the ballast retaining wall.

RDSO’s Remark: Bridge directorate have finalised drawing with arrangement for passing signal and telecom cables. Drawing Number M-0010 has been issued for PSC slab and PSC girder. Box type arrangement has been provided in 18.3m PSC I-girder and 24.4 m PSC box girder.

2. Communication interface for signalling system/sub-system should be deigned &

standardised to enhance reliability & performance of system/sub-system.

RDSO’s Remark: Telecom directorate shall assist Signal directorate for any such requirements.

3. Provision of common earthing for signal and telecom installations can be

considered at any way side station.

RDSO’s remarks: Telecom and signalling earths provided for protection (other than functional earths) can be combined. However final view can be taken after taking Signal directorate view on the subject.
