Introduction


18/120




FTDG-600-01-41487


FW 4070 is a multi-service provisioning platform with add/drop, terminal and cross-connectfunctionality for universal installation at all network levels.

All applications can be implemented using a single subrack. Reconfiguration duringoperation is possible.

FW 4070 transports data signals and standard voice based traffic over one single platform.For transporting data in the most economic way, the FW 4x70 product line combinestechnologies such as Generic Framing Procedure (GFP), Link Capacity Assignment Scheme(LCAS), and Resilient Packet Ring (RPR) with the reliability and robustness of SDHnetworks and a quality of service.

FW 4070 network elements provide full cross-connectivity between all interfaces. The

capacity of the Low Order (LO) switching network is up to 16 16 VC-4-equivalents. Thisapplies to VC-4 layer and to all cross-connection types (including unidirectional, bi-directionaland broadcast (HOCC 1:4, LOCC 1:63)).

FW 4070 can be used as:

TMX (terminal multiplexer)

ADM (add/drop multiplexer)

in multi-service transport and aggregation/switching network applications.

State-of-the-art protection switching mechanisms are supported to enable an optimumnetwork with the very highest reliability possible depending on the relevant networktopology and the requirements of the network operator, see Chapter 5.7.

FW 4070 is single subrack equipment.

For detailed information about FW 4070 figures see Chapter 2.1.

2.1 Application Types

In Chapters 2.1.1 to 2.1.3, an overview on usage of the FW 4070 is provided.

2.1.1 Terminal Multiplexer Type

The FW 4070 terminal multiplexer(TMX type) can be used in such configurations as point-to-point connections or as feeder terminal for traffic aggregation to core networks.

4.5 FE Data Service Applications

FW 4070 provides data transport over SDH, and offers various data applications in addition

to traditional TDM applications.

The FW 4070 system supports the following three FE data transmission services:

1) Ethernet Private Line (EPL)

2) Ethernet Virtual Private Line (EVPL)

3) Ethernet Private LAN (EPLan)

4.5.1 Ethernet Private Line (EPL)

FW 4070 Ethernet Private Line Service offers dedicated, point-to-point Ethernet connectivity

at Fast Ethernet speeds(10 Mbps or 100 Mbps).

The provision of higher bandwidth Ethernet connectivity not only reduces costs but also

enables new applications to be delivered across the Enterprise WAN.

4.5.3 Ethernet Private LAN (EPLan)

The Ethernet Private LAN (EPLan) service provides multipoint connectivity over dedicatedbandwidth, i.e., it may connect two or more subscribers (customer). Subscriber data sent

from one customer can be received at one or more of the other customers. Each site

(customer) is connected to a multipoint-to-multipoint EVC and uses dedicated resources so

different customers Ethernet frames are not multiplexed together. As new sites (customers)

are added, they are connected to the same multipoint EVC thus simplifying provisioning and

service activation. From a subscriber standpoint, an EPLan makes the MSTP network look

like a LAN.

EPlan (Ethernet Private LAN) architecture differs from EPL in that rather than use a

predefined mapping between VLAN tags and link connections, the operators network

equipment, uses Ethernet switching (i.e. Bridge learning) to pass Ethernet frames to theappropriate link. However this makes it difficult to guarantee performance as network

Ethernet switching introduces additional latency and probability of increased packet loss.

FW 7020 brings multiple WAN interfaces into a layer 2 switching. Customer service can be

delivery through dedicated VCGs with little latency and little packet loss. WAN interface can

be provisioned individually by using PhotonicVision SNM.

(SFP modules) in several distance variants up to 622 Mbit/s.On the tributary side, the FW 4070 supports various PDH, Ethernet, and STM-1 interfaces.

The central element of FW 4070 includes system controller, cross-connect matrix, and timingfunctions.

5.2.2 Switch Fabric Functions

The switching device provides high order (HO) and low order (LO) switching at the same

time.In the switch matrix, SNCP is implemented for each VC-4/VC3/VC12 switching hierarchy and

input signal. The configuration of the switch matrix and of the SNCP is done by software

support.

Capacity of the Cross-connect Matrix

The FW 4070 has the following cross-connection capacity:

HOCC: 8 8 VC-4 (with STM-1 MB) and 16 16 VC-4 (with STM-4 MB)

LOCC: 504 504 VC-12 (with STM-1 MB) and 1008 1008 VC-12 (with STM-4 MB)

Cross-connection

All types of cross-connections are possible. The switch matrix is a non-blocking square

structured matrix for point-to-point and point-to-multipoint connections.

Granularity

The configurable and simultaneously usable switching hierarchies of the matrix are VC-4,

VC-3, and VC-12.

HO and LO VC-n Connectivity

The switching matrix allows the following connections:

Unidirectional connections

Unidirectional point-to-multipoint (including 1+1 SNC head end)

Bi-directional connections

Broadcasting (HOCC 1:4, LOCC 1:63)

Drop and continue

Selector 21 (protected tail end for 1+1 SNCP)

Concatenation

Virtual concatenated VC-12 signal and protection switching are supported. The group of

constituent paths that belong to a concatenated signal is determined by the

Telecommunication Network Management and written to an internal configuration table.

Using this information, the FW 4070 software is able to set signal fail or signal degrade

alarms for all paths of a concatenated signal channel. In order to keep the (differential) delay

of the signals low, all constituent paths of a concatenated signal must be on the same optical

trail; it results in a bundling rule for the Telecommunication Network Management.

The FW 4070 transmits SDH and PDH signals. Fig. 5.3 shows the organization and

relationship of SDH and PDH multiplex structures.

The FW 4070 implements the following HO/LO multiplexing and mapping methods:

VC-4 containers are aligned (with frame offset information) with an AU-4, according to

ITU-T G.707. The AU-4 may further be mapped via AUG-1 into STM-1 or via AUG-1 and

AUG-4 into STM-4.

VC-3 containers are aligned (with frame offset information) with a TU-3, according to

ITU-T G.707. The TU-3 is further mapped via TUG-3 into VC-4.

VC-12 containers are aligned (with frame offset information) with a TU-12, according to

ITU-T G.707. The TU-12 is further mapped via TUG-2 and TUG-3 into VC-4.

5.2.3.2 PDH Mapping into SDH Containers

The FW 4070 implements the following mapping of PDH signals on SDH containers:

34-Mbit/s and 45 Mbit/s signals are mapped into a VC-3 asynchronously, according to ITU-

T G.707. The VC-3 is further mapped on a VC-4, via TU-3 and TUG-3.

2-Mbit/s signals are mapped into a VC-12 asynchronously, according. to ITU-T G.707. The

VC-12 is further mapped on a VC-4, via TU-12, TUG-2 and TUG-3.

1.5-Mbit/s signals are mapped into a VC-11 asynchronously, according to ITU-T G.707. The

VC-11 is further mapped on a VC-4, via TU-12, TUG-2 and TUG-3.


38/120




FTDG-600-01-41487


5.2.3.3 Ethernet Packet Multip lexer and Mapping Functions

The FW 4070 supports Ethernet frame mapping into SDH containers. So LAN traffic can be

transported over different SDH payload sizes (requires encapsulation by using anappropriate protocol and mapping of the resulting frame into a SDH container).

For encapsulation, the Generic Framing Procedure (GFP-F acc. to ITU-T G.7041) protocol isused. The encapsulated protocol frames can be mapped into different SDH containers usingthe virtual concatenation technique.

Ethernet Mapping into SDH Containers

FW 4070 supports a flexible mapping scheme:

Ethernet Mapping into LO virtually concatenated Containers

Mapping into VC12, VC-12-Xv (X = 1 to 46).

This mapping function is supported for the Fast Ethernet ports.

Encapsulated GFP-F frames can be mapped into different Low Order container sizesproviding a scalable solution that can cover network applications with very different transportcapacity requirements.

GFP-F Mapping

The Generic Framing Procedure (GFP) is supported by the Fast Ethernet interfaces.

GFP provides a generic mechanism to adapt traffic from higher-layer client signals over an

octet synchronous transport network. This is a simple and robust encapsulation method for

packet traffic. All of the relevant MAC layer information, from destination address through

Frame Check Sequence (FCS) inclusive, is preserved intact by the mapping.

The FW 4070 uses a PDU-oriented, frame-mapped adaptation mode (GFP-F) for client

signal adaptation.

GFP-F does not rely on flag characters and associated control escape octet for frame

delineation purposes as HDLC does. Instead, GFP-F uses a variation of the HEC-based

(Header Error Control) frame delineation mechanism defined for Asynchronous Transfer

Mode (ATM). This avoids non-deterministic expansion of the client signal due to insertion of

control escape characters.

5.2.4 SDH Overhead Processing Function

5.4 Clock Pulse Supply, Synchronization

Every network element (NE) clock may be synchronized by a very accurate timing source,

normally by a primary reference source (PRC) according to the master-slave principle. TheSETS is responsible for generation of system and output clock signals.

According to the ETSI recommendation, T3 T2 and T1 are the synchronization timingsources, T0 is the internal NE system clock and T4 is the timing output interface.

Fig. 5.45.4 Timing Source Selection

5.4.1 Available Timing Sources

The SETS synchronization for the FW 4070 is derived from any of the following externalports:

From any STM-N ports (T1, T2)

From a station clock from the central office

From an E1 tributary input (T3) , or

From the internal Stratum 3 clock (ITU-T G.813 Option 1)( only apply to the STM-4 Main

Board)

The FW 4070 supports SDH Synchronization Status Message (SSM) on STM-4 interfaces,STM-1 interfaces, and the framed 2 Mbit/s synchronization output signal (connected to thestation output clock).

A Synchronization Status Message (SSM) signal can be used to transfer the signal qualitylevel throughout a network. This guarantees that all network elements will always besynchronized to the highest quality clock available.

The SSM function on the FW 4070 can be user provisioned as enabled or disabled. Whenthe SSM function is disabled, all STM-N interfaces and framed 2 Mbit/s synchronizationoutput signal interface will send out a DNU (do not use for sync) signal.

There are 4 possible quality levels specified in the SSM for timing reference sources: PRC,SSU-A, SSU-B, and SEC. In addition, DNU is specified in SSM. The quality of each timingreference source can either be retrieved from the incoming the SSM or provisioned from thenetwork management system.

The FW 4070 supports the synchronization source switching algorithm based on SSMdefined in ITU-T G.781.

The wait-to-restore (WTR) time for the timing reference source is between 0-12 minutes andcan be set from the network management system in minute increments. The default value is5 minutes.

The System Main Board provides one of the following interfaces to offer synchronization toexternal devices:

2 Mbit/s, framed or unframed

2 MHz

5.4.4 Real Time Clock

For time stamps (time and date) in FW 4070 error and operational messages, a real timeclock is available (within the SETS).

The date and time for the real-time clock within the NE can be set and requested from theLCT/OS.

5.5 Laser Safety Shut-down

To prevent possible personal injury from emerging laser light in the case of a line interruption

(e.g. fiber break), a laser safety shut-down function (ALS Automatic Laser Shut-down) has

been specified in ITU-T G.958 and ITU-T G.664. In the event of signal failure at the optical

receiver of FW 4070 equipment, the laser transmitter is switched OFF in this equipment for

the opposite direction, removing the disturbed field from operation. The laser transmitter is

then switched ON cyclically every 100 seconds for approximately 2 seconds of testing. If the

receiver on the concerned device receives a valid signal again, the laser transmitter for the

opposite direction is immediately put into continuous operation again.

When switching ON internal power supplies or after a laser switch-off caused by total failure

of the power supply in the telecommunications center, the laser transmitter(s) must be forceswitched ON for approximately 2 seconds after the permissible operating conditions have

been reached. The line is automatically put back into operation in this method.

In the case of line interruption or for maintenance work, the laser transmitter must be

switched on manually for approximately 2 seconds or approximately 90 seconds (for test

purposes). The transmitter is switched back ON via the operating terminal.

No ALS function is supported for Ethernet interfaces. These interfaces fulfill the requirements

of laser hazard level 1 without ALS.ii

5.6 Software/Firmware

The System Controller (SC) located in main board is equipped with micro controllers for

monitoring, controlling, and maintaining status information. They are programmed withembedded firmware held in Flash-EEPROMs.

A software download facility is available. The download can be done remotely or locally via

the element manager or local craft terminal.

The internal configuration MIB database of the system can be uploaded and downloaded. It

is stored redundantly and robust to any card failure.

5.7 Protection Switching

FW 4070 supports the following SDH traffic protection functions:

2-Fiber Shared Ring Protection Switching (MS-SPRING) on the STM- 4 interface.

Traffic protection functions on the STM-N multiplex section layer (Linear MSP)

Subnetwork connection protection (SNCP) functions on the VC-4, VC-3, and VC-12 path

layers.

Traffic protection functions are partly coupled with equipment protection features. This

generally achieved by including some HW components (e.g. SFP modules) within a

protected signal section.

5.7.1 2-Fiber Shared Ring Protection Switching (MS-SPRING)

A 2-fiber MS-SPRING is a bidirectional (duplex transmission) ring where both directions oftraffic transmission use the same set of nodes under normal conditions. When there is afailure on the working path, the traffic will be switched to protection bandwidth.

The changeover criteria are specified individually when configuring the network element. AnAutomatic Protection Switching (APS) protocol is required.

The switchover to the protection bandwidth occurs in revertive mode, i.e. if there was aswitchover to the protection bandwidth as a result of a working bandwidth fault, there isautomatic switchback to the original path once the fault is rectified.

5.7.2 1+1 Linear Mult iplex Section Protection (MSP)

Protection switching is fulfilled in the equipment according to the relevant ETSI/ITU-T

standards ETS 300417-3-1 and G.841, respectively. Fig. 5.6 shows the general switchingarchitecture for completing a linear 1+1 MSP with two line interfaces:

Fig. 5.65.5 Linear 1+1 MSP, Fault-free Case

In 1+1 Linear MSP, the client traffic is always transmitted over the working and protection

path simultaneously (MSP bridge).

In case of fiber break (Fig. 5.7), the SDH card detects the fault and the MSP selector

automatically selects the incoming traffic from the protection path.

(SFPs) the 1+1 MSP protection always comes with some kind of hardware protection.

FW 4070 MSP supports both single-ended and dual-ended MSP (revertive or non-revertive).

All SDH traffic interfaces of FW 4070 support 1+1 MSP protection scheme.

5.7.3 1+1 Path Protection Switch ing (Subnetwork Connection Protection,

SNC/I)

The data signal is transmitted via two different paths and can be implemented in line or ring

structures (Fig. 5.6).

SNC protection is a linear protection scheme which can be applied on an individual basis to

VC-n signals. It does not need to be used on all VCs within a multiplex section. It does not

need to be used on all LO VCs within a HO VC. The SNC/I mechanism switches on server

failures using inherent monitoring as defined in ITU-T G.841. A Protection Protocol is not

required.

The switchover between the working and the protection path can be configured as non-revertive or revertive mode. In the non-revertive mode, if there is a switchover to the

protection path as a result of a transmission fault, there is no automatic switchback to the

original path once the fault is rectified, but only if there is a fault on this new path. In the

revertive mode, if there was a switchover to the protection path as a result of the working

path fault, there is an automatic switchback to the original path once the fault on the working

path is rectified.

In FW 4070, the 1+1 SNCP can be categorized into High Order SNCP and Low Order SNCP.

5.8 Operating Terminal PhotonicVision SNM FW 4070 LCT

Network elements can be operated and monitored via the software PhotonicVision SNM

FW 4070 LCT software.

The FW 4070 LCT is used primarily for local management and commissioning of network

elements. The LCT is connected via the Management Interface and allows for access to the

network element locally or remotely.

For further information about operation, control and monitoring via FW 4070 LCT operating

terminals see FW 4070 LCT User Manual.

5.9 Connection to Network Management Systems

Fig. 5.9 shows the integration of FW 4070 network elements in the TMN system. Access

from TMN to FW 4070 NEs is fulfilled via SNMP over TCP/IP (direct access) and SNMP overTCP/IP/PPP or TCP/IP/HDLC or TCP/IP/OSILight (via dedicated SOH channels within traffic

links DCCM or DCCR) interfaces.

OSILight is an IP over CLNS (Connectionless Network Service) Tunnel protocol stack.

OSILight lets IP traffic be transported over Connectionless Network Service; for instance, on

the data communications channel (DCC) of OSI based SDH equipment. OSILight enhances

interactions with the CLNS network, allowing IP packets to be tunneled through the

Connectionless Network Protocol (CLNP) to preserve TCP/IP services.

The selection of PPP, HDLC, or OSILight is user configurable.

6.3 Power Supply Card PWR

The FW 4070 supports both AC and DC power supplies as described below.

6.3.1 DC Power Supply Card

Function

The FW 4070 DC power supply card provides two 48V (range 38 V to 72 V) DC power

supply interfaces. It converts the input supply voltage into regulated operating secondary

voltages. The outputs are isolated from the input. All output circuits have a common

reference point, which is connected to the grounding layers on the backplane.

There are two external replaceable fuses and two green color LEDs labeled PWR on the

faceplate. LED ON indicates that the corresponding power supply is on; otherwise the power

supply is off.

The power supply card is a pluggable module.
