1. INTRODUCTION

A number of boards in the ISPBX system have DIL switches and/or straps, which have to be set in the correct position during installation or replacement of the boards. This chapter contains all the boards which do have those switches/straps. Also directions are given how to set those switches/straps to suit a particular mode of application. In general the PCT boards have more than one circuit mounted; so in that case the switches/straps have to be set for each circuit individually.

2. ANALOGUE LINE CIRCUITS

2.1. ALC-A/B

An ALC-A/B provides the 2-wire line interface between an analogue extension and the ISPBX; see the figure below. The ALC-A board has 8 of those interfaces (circuits).

Figure 2-1 ALC Interfaces

The a/b wires of the ALC-A/B are connected to the MDF via front connector FBC.

Figure 2-2 Layout Front Connector FBC

2.2. ALC-E

An ALC-E provides the 2-wire line interface between an analogue extension and the ISPBX. The ALC-E board has 16 of those interfaces (circuits).

It is possible to use only eight of the ALC-E circuits by means of strap X1-1. In this way an ALC-E can also be used as an ALC-A.

The strap is drawn in position 101-102 for 16 ALC-E circuits: for 8 ALC circuits the strap must be placed in position 102-103.

2.4. ALC-G

An ALC-G provides the 2-wire line interface between an analogue extension and the ISPBX. The ALC-G replaces all versions of the ALC-E and ALC-F. It can not be used instead of the ALC-A.

The ALC-G is a board with 16 interfaces (circuits). Connectors are fitted to the board for a possible future extension board. The hardware is designed in such a way that the adjustment range of the transmission characteristics matches with the currently known country requirements. The maximum line current is 35 mA and reverse polarity is supported.

Note: The line polarity of the ALC-A and the ALC-E is the opposite of the line polarity of the ALC-F and the ALC-G.

Two packages can exist on a card, an initial and a downloaded package. The initial package is factory-installed and can only be modified in the factory.

PPU systems and systems of PMC release < or equal 405.08/505.08 only use an initial package on the board, even if another package is downloaded. The transmission plan is set by means of the DIL-switches.

As from SSW 805.28 and PMC packages 405.10/505.10,. the ALC-G uses only the downloaded package. In this case the DIL-switches are not used for the transmission plan.

Without downloading, the card can be used on SSW 640/SSW2xx/SSW300/SSW7xx/SSW8xx up to PMC 405.08/505.08 (and not with PMC 405.09/505.09).

• Transmission PlansAn ALC-G board can simultaneously contain two downloaded transmission plans, each circuit can have either one of these transmission plans. The transmission plan is specified with the bytes 13 and 14 of signalling group 32xx. When bytes 13 and 14 are 0 (default), then the used transmission plan is specified with the bytes 33 and 34 of signalling group 9800. Bytes 33 and 34 are 1 by default.A circuit can alternate between the two downloaded transmission plans.Example:Byte 13 of signalling group 3205 = 3 (English), transmission plan A.Byte 14 of signalling group 3205 = 1 (International), transmission plan B.Bit 4 of sigalling group 3205 = 0, so 3205 uses plan ABit 4 of signalling group 3204 = 1, so 3204 uses plan BBit 4 of signalling group 3210 = 0, so 3210 uses plan A.ASBRDS:11,1,6,3205,35;all circuits have plan A.CHPCTB:11,1,12,3204;only circuit 12 uses plan B.

Page 15: Mnp3810eMaintenance Part3-Board Interface & Strap

11

CHPCTB:11,1,15,3210;circuit 15 uses plan A.

• Signalling ParametersSignalling parameters are downloaded for all circuits on an ALC-G board, two of these signalling parameters are projectable for each individual circuit: on/off hook debouncing and ground key debouncing time.

The ALC-G has two LEDs; the meaning is given in the table below.

2.5. ALC-GP

The ALC-GP board (ALC-General Protected, 12NC: 9600 040 28000) has the same functionality as the ALC-G except for a protection circuit per line to fulfil the requirements for the Chinese market (YD/T 950-1998). These requirements include the ITU-T K.20:1996 recommendation.

2.6. ALC-G(R)

The ALC-G(R) is the redesigned version of the ALC-G and ALC-GP.The ALC-G(R) has the same functionality as the ALC-GP : it provides the 2-wire line interface between an analogue extension and the ISPBX.The board contains 16 interfaces (circuits). The ALC-G(R) replaces all versions of the ALC-G and ALC-GP. It can not be used instead of the ALC-A. See the description of the ALC-G for more details of the LEDs, connectors and DIP Switch Settings.

2.7. ALC-GM/GD

The ALC-GM/GD replaces all versions of the ALC-E, ALC-F and ALC-G/GP/G(R). See the description of the ALC-G for more details of the LEDs, connectors and DIP Switch Settings. The ALC-GM/GD provides the 2-wire line interface between an analogue extension and the ISPBX :

- the ALC-GM is a mother board with 16 interfaces (circuits).- the ALC-GD is a daughter board with 16 interfaces (circuits).

When the daughter board (ALC-GD) is present on the mother board (ALC-GM), the combination offers 32 interfaces in total.

The ALC-GM fits in a PM2500 shelf just like an ALC-E or ALC-F (all 16 circuits). However the combination ALC-GM plus the daughter board ALC-GD is mechanically to wide to fit in a PM2500 board position.

Note that the ALC-G/GP/G(R) can not be used as a motherboard to mount the ALC-GD daughterboard !!!

Projecting aspects :

- the ALC-GM with the daughter board ALC-GD has to be projected as one ALC with 32 circuits, board type 59 and signaling group 321C.

- the ALC-GM without the daughter board ALC-GD has to be projected as one ALC with 16 circuits, board type 6 and signaling group 3205 or 3210.

- signalling group 321C is supported from PMC packages 405.10.01 en 505.10.01 and all PMC-G 810 packages.Board type 59 is supported from SW805.28 onwards.

3. KEY TELEPHONE LINE CIRCUITS

3.1. KTLC01/02/03

The KTLC provides a 4-wire interface between up to 8 SOPHO SETs of the K series (K160, K260, K261, K365) and the ISPBX. The a/b wires are used for voice; the c/d wires are used for control information from/to the SOPHO SET.

All four wires are connected to the MDF via front connectors FBA & FBD.

Figure 3-1 Layout Front Connector FBA & FBD

There are two types of KTLCs: the 8 circuits per board versions with a fixed transmission plan and the 8 circuits per board version with a software selectable transmission plan.

The fixed transmission plan KTLCs are:

- KTLC01 :according to transmission plan 01 (e.g. required for the Netherlands);- KTLC02 :according to transmission plan 02 (e.g. Germany);- KTLC03 :according to transmission plan 03 (e.g. United Kingdom).

The software selectable transmission plan KTLC is KTLC-A: transmission plan set by the signalling block. The transmission plans supported by the KTLCs can also be used in other countries next to the ones listed above.

The KTLC to be used in a specific country depends on the local transmission plan. The transmission levels of the various KTLC boards are selected by means of strap settings; see figurefor the location of the straps.

• Strap X1.1The straps of X1.1 are used to set the mode of operation of the KTLC; see the table below. For normal operation of the key telephones, all straps of X1.1 must be installed.

Table 3-1 KTLC Mode of Operation

• Strap X2.1This strap is used to connect or disconnect the back-up battery of the memory circuits on the KTLC board. With the battery connected these circuits retain user-defined data during a system power failure. User defined data is also retained when the board is removed from the shelf, but only if the shelf has been powerless during removal!User defined data is not retained when the board is removed from the system.- operation with battery back-up (normal operation):strap on position 101-102.- operation without battery back-up (factory setting):strap on position 102-103.When removing the KTLC from an operational system, remove and re-install the strap on 101-102 for about one second to clear the contents of the memory in order to avoid the possible corruption of the user programmed data.

Note: When the board is stored the strap must be positioned on 102-103 to prevent a fully discharged battery.

• Strap X3.1The straps of X3.1 are used to select the correct transmission levels; the setting of X3.1 depends on the type of KTLC and the local transmission plan.Tablegives the strap settings for the transmit levels; tablegives the settings for the receive levels. Both tables indicate the strap settings per transmission plan for a few countries. For countries not mentioned in the tables one should use the default settings of the KTLC; these settings are:- KTLC01 : the settings for the Netherlands.

• Strap X2.1This strap is used to connect or disconnect the back-up battery of the memory circuits on the KTLC board. With the battery connected these circuits retain user-defined data during a system power failure.User defined data is also retained when the board is removed from the shelf, but only if the shelf has been powerless during removal!In all other circumstances this strap has to be removed for a while before inserting the board into the shelf. An example of such a situation is when removing the board with the shelf powered up. The data stored in the on-board processor and associated memory is mutilated in that case: the strap should be removed before re-inserting it so that the processor and memory can be reset.- Operation with battery back-up (normal operation):strap present;- Operation without battery back-up (factory setting):strap not present.

4. DIGITAL LINE CIRCUITS

4.1. DLC-A/B/C/D

The Digital Line Circuit-A or B (DLC-A, DLC-B) provides a number of two-wire 2B+D accesses to the ISPBX. Each access is a Philips proprietary Usinterface at a nominal bit rate of 152 kbit/s. The Usinterfaces can be used to connect terminal equipment, such as SOPHO-SET S-range and LAMs. The DLC-A/B/C/D can operate in combination with a Line Driver Card (LDC) when line powered terminals are connected.

The DLC-A controls a maximum of 3 DLC-Bs placed in the same Unit Group; the DLC-C controls one DLC-D placed in the same Unit Group: controlling is done via frontcabling; see figure.

The number of Usinterfaces of the DLC boards is:

- DLC-A : 3x(2B+D) Usinterfaces.- DLC-B : 4x(2B+D) Usinterfaces.- DLC-C : 7x(2B+D) Usinterfaces.- DLC-D : 8x(2B+D) Usinterfaces.

Figure 4-9 Meaning of strap X5.1 ... X5.30

The strap at the receiver side has the reference Rn and at the transmit side Tn: R stands for receiver, T for transmit and n is the related line number.

When the DTX-I is used as a DTU-BA, the DTU-BA can operate either as Terminal Equipment (TE) or as Network Terminator (NT) in a network. When changing over from TE to NT (or vice versa) also the projecting data has to be changed. Check the projecting data to see how the DTU-BA is projected.

• Strap SettingsEach circuit of the DTX-I can be used to connect:

When a DTX-I is projected as a DLC-I or a DTU-BA the following restrictions apply:- A maximum of 7 lines (0 ... 6) can be used, even in case of a DTX-I(15);- No mix of trunk and terminal circuits is allowed;- The board is not downloadable.

WARNING: BE SURE THAT BOTH THE RN AND TN STRAPS OF A LINE ARE MOUNTED ON EQUAL POSITIONS. IT IS NOT ALLOWED TO

- a terminal : connect, on Rn and Tn side, the straps 101&102 to deliver the line power;

- a trunk line (TE side) : connect, on Rn and Tn side, the straps 102&103: no line power, no sync. (=slave);

- a trunk line (NT side : on Rn and Tn side, no straps made: no line power, sync. is delivered (=master).

HAVE ONE STRAP MOUNTED ON POSITION 101&102 AND THE OTHER STRAP ON POSITION 102&103.DO NOT MOUNT A STRAP ON X2.1 AND X3.1. THIS WILL DAMAGE THE PROCESSOR AND POWER SUPPLY.

• Terminal EquipmentWhen the DTU-BA is used as interface to the PSTN or another PBX it operates as a TE. It expects to receive an external clock reference from an NT to synchronise with. This means that a clock signal is available on frontconnector FC 101; this clock signal can be used as the input clock for a CRU, when necessary.

• Network TerminatorWhen the DTU-BA is used as an NT, it operates as the master and it provides the synchronisation clock for the TE. This means that no clock signal is available on front-connector FC 101.

When two DTX-I (used as DTU-BAs) form one transmission link (max. distance 1000 meters) one DTX-I must be strapped as DTU-BA NT and the other as a TE.

4.5. DTX-I(R)

The DTX-I(R) is the redesigned version of the DTX-I. The DTX-I15(R) provides 15 four-wire 2B+D accesses to the ISPBX. Each access contains an S0 interface which can be configured as follows :

- as an extension interface (network side) to connect ISDN terminal equipment;- as a trunk/tie line interface (user side) to make a connection to the ISDN.

Note: There is also a stripped version of the DTX-I(R) which provides 7 four-wire 2B+D S0 interfaces : the DTX-I7(R).

Strap Settings

Note that a strap summary is printed on the DTX-I(R) board between connectors FBA and FBD. Each circuit of the DTX-I(R) can be used as :

- an EXTension to connect ISDN terminalsThe straps must be placed on position 101&102 (factory setting).The transmit and receive pairs of an interface are connected to -40 V and system ground respectively, in order to power the connected terminals.

- a Trunk lineThe straps should be parked in the position 102&103.The transmit and receive pairs are isolated from -40 V and ground, in order to avoid high ground currents flowing between two systems.

Front connectors

At the front of the DTX-I(R) four F122 connectors (FAB, FBA, FBD & FCC) are available to connect the four-wire S0 interfaces. The pinning of these connectors is identical to the DTX-I.

Clock Reference

When the DTX-I(R) is used as interface to the PSTN or another PBX it operates as a slave (TE). The PBX may need an external clock reference from the master network (NT) to synchronise with. For this purpose a clock signal is available on front connector FC 101; this clock signal can be used as the input clock for a CRU, when necessary.

4.6. DLX-U

The Digital Line eXtensions - Upninterface (DLX-U) provides 2 wire accesses for extensions with Upninterface. There are two types: the DLX-U(15) and DLX-U(31).

The DLX-U(15) provides 15 accesses.

The accesses are 2B+D types which can be used in two different modes (the 'board type' and the 'signalling group' in the projecting data determine the mode):

The DLX-U(31) provides 31 accesses. The accesses are 2B+D types, but only one B-channel is applied. This is called the 1B mode.

The circuits in relation to the lines differ per DLX-U and operating mode:

- 1B mode : This means that only one B-channel is applied and the second remains unused.

- 2B mode : This means that both B-channels are applied.

- DLX-U(15) in 1B mode:circuit 0: PPU - DLX-U control channel (IMP)circuit 1 ... 15: access 1 ... 15

- DLX-U(15) in 2B mode:circuit 0: PPU - DLX-U control channel (IMP)circuit 1: not usedcircuit 2 & 3: access 1circuit 4 & 5: access 2

4.7. DLX-L

The Digital Line eXtension-Long line interface provides accesses for extensions with a Uk0 (2B1Q) interface.

The DLX-L provides 15 accesses with 2B+D interface of which :

- one B-channel is used (1B mode, Philips proprietary)- two B-channels are used (2B, ITU compatible).

The mode depends on the signalling group and board type. Mixed mode (1B and 2B) on one board is not possible.

The DLX-L has the following characteristics:

- It has Uk0 interfaces: a 2-wire, 98 ohms balanced, 2B1Q interface with a datarate of 144 kbits/s;

- On layer 3, it supports TMP, 1TR6 and Euro (ETSI): protocol selection on layer 3 is automatic;

- It is able to support power to the terminals, nominal -58 volts with a current of 45 mA;- It is intended to service voice and data terminals;- When no Uk0 terminal is available, the board can be connected via a Private Network

km (0.4mm cable) or 5.5 km with 0.5mm cable (Filotex 0.5 cat.3).

The layout of the front connectors of the DLX-L is the same as for the DLX-U.

The LEDs on the board have the following meanings:

Table 4-1 Meaning of the LEDs

• PNT-LThe PNT-L is a private network terminator that converts the Uk0 (2B1Q) 2-wire interface provided by the DLX-L into a standard 4-wire S0bus. The use of a PNT-L for connecting terminals to the DLX-L is necessary when no terminal with the Uk0 (2B1Q) interface is available. The PNT-L is mains-powered and provides power to the connected terminal(s). The interface between DLX-L and PNT-L is powered by the DLX-L. The PNT-L is transparent for the layer 3 protocols (TMP, 1TR6 and Euro-ISDN).

5.1. ATU-SS

The ATU-SS (Subscriber Signalling) is a 2-wire line interface which connects the ISPBX system to a PSTN. The a/b wires of the ATU-SS, when not interworking with a Metering Circuit (MC) or Emergency Switch-over Unit (ESU), are directly connected to the MDF via front connector FBC.

When the ATU-SS interworks with MCs and/or ESUs the a/b wires are, via a front connector, first connected to an MC, MCE or ESU card and via that card to the MDF.

Note: Depending on the type of ATU-SS the card accommodates 4 or 6 ATU-SS circuits.

Figure 5-1 Layout Front Connector FBC

If Metering Circuits are used, the outputs of the detectors are connected to the ATU-SS card via a separate front connector. The wires to the metering level detectors on the ATU card are MD1 ... 6 and GND1 ... 6.

5.3.3. ATU-EM-D

The ATU-EM-D is designed for special projects only.

This board serves as an interface between the SOPHO and equipment using a digital (64 kbit/sec) interface as described in the ITU recommendations G703.1.

The board contains 4 circuits. The data channels are 4-wire for a co-directional connection (2 pairs: one in each direction) and 8-wire in case of a contra-directional interface (2 pairs for data, one in each direction, and 2 pairs for timing signals, one in each direction). The signalling is E&M signalling via separate E&M wires as is used on the ATU-EM boards. The synchronisation can be extracted from the incoming data stream (circuit 0 only) or from the special input connector on the board.

5.7. ATU-ST

5.7.1. ATU-ST02/12

The ATU-Special Type 02 or 12 (ATU-ST02 or ATU-ST12) is a 2-wire line interface which connects the ISPBX system to a PSTN. The line signalling which is in use in this type of ATU is an asymmetrical type of signalling with different potentials on the a&b-wires. The signalling voltage is -60 V; it is derived from the PSU-D and supplied to the ATU-ST card via a line feed connector FCC and FCD.

Note: The ATU-ST02/12 type is subdivided into a version with 2 or 4 ATU-ST02/12 circuits.

Figure 5-18 Layout Front Connector FBC

If Metering Circuits are used (only for the 2 circuit versions), the outputs of the detectors are connected to the ATU-ST card via a separate front connector. The wires to the metering level detectors on the ATU card are MD1&2 and GND1&2.

In figure and figure below the straps LKA ... LKK are given as A ... K; the prefix indicates the circuit number; e.g. strap 3.D indicates strap LKD of circuit 3.

Table 5-29 Settings for 2-wire or 4-wire mode

The straps LKA ... LKK serve the following:

- LKA and LKB serve for the selection of DC signalling via the a and b wires (2-wire) or the a/b and c/d wires (4-wire).

- LKC and LKD select the source and terminating impedances.- LKE selects the transformer DC current cancellation for 2-wire mode.- LKF selects the duplexor circuit (hybrid) for the 2-wire mode.- LKG selects the level adaptors for the 2-wire or 4-wire mode.- LKJ and LKK serve for reversed connection of the polarized seizure detector, which is

necessary for correct functioning due to the cross connected a/b and c/d wires in the 4-wire mode.

- LKH determines whether the pads for an unamplified line are included or not in the 4-wire mode. For long line compensation or in case of an unamplified line the strap is absent, otherwise present.

In the figures below the circuits are strapped for unamplified lines.

5.8. ATU-IL

The ATU-Inter-register L1 (ATU-IL) is a 4-wire line interface which connects the ISPBX system to another PBX. The signalling used is an inter-register signalling (L1) intended for long distances and connections via leased lines. It is an AC signalling system consisting of inband tone signals. Two unidirectional 2-wire links are used for transmission of both voice and signalling tone in either direction. Per link voice and signalling is never sent at the same time.

All wires of the ATU are directly connected to the MDF via front connector FBB.

5.8.1. ATU-IL01/IL03/IL13/IL31

The straps on these ATUs are used to select the short/long line operation and the direction: transmit or receive.

The first identifier of the straps (1 ... 4) indicates the ATU circuit 0 ... 3.

For all circuits the following applies:

- X.-1 : not installed : Long Line Outgoing (transmit);installed : Short Line Outgoing (transmit).

- X.-2 : not installed : Long Line Incoming (receive);installed : Short Line Incoming (receive).

The ASU-G is for special projects only.

The Analogue Subscriber line Unit General (ASU-G) is a multi functional board which contains 16 trunk lines. These 16 two-wire analogue interfaces connect the SOPHO iS3000 system to the PSTN. Compared to the ATU-Gx, the ASU-G has no metering function and no emergency switch function. Also, the ring frequency, the ring detection level and the DC resistance range are not projectable.

The ASU-G supports two signalling types:

- Subscriber Signalling (SS): this is the signalling normally used between the PSTN and a subscriber. An ISPBX using the ASU-G subscriber signalling, is treated as a normal subscriber by the PSTN.

- Polarity Detect Signalling (PD): This signalling type takes also the polarity changes of the transmission line into account.

The ASU-G is designed according to the transmission standards as specified in ETSI ETS 300 004. Furthermore specific (country-dependent) parameter values are possible for:

- Input and output levels;- AC impedance;- Balance impedance.

The transmission table, which is country-dependent, is downloaded when the board is plugged in or switched on. Only downloading of a transmission plan is possible. Only one transmission plan can be active on the board.

The board contains one LED. During normal operation the LED is off. When the board is not operational or there is a hardware error during operation, the LED is on. Also when downloading takes place, the LED is on.

The ASU-G may be placed in any standard PCT position, maximum 2 boards per Unit Group.

The ASU-G has two F122 front connectors 16-pins (FAD and FCA) to connect to the subscriber lines.

6.4. DTU-PU

The Digital Trunk Unit for Primary Rate Universal (DTU-PU) can operate as a DTU-CA, DTU-CC or DTU-PR. There are two versions of the DTU-PU: version 1 and 2. The DTU-PU version 2 offers the DTU-CC networking applications when it is placed in a standard PCT position in the PM1100; this is not possible with version 1. You can recognize a DTU-PU version 2 by the presence of a DIP-switch marked "CC".

The DTU-PU carries a DIP switch block (S.1) and a group of eight straps (X1.1).

6.5. DTU-BA

The DTU-BA provides the interface between the digital switching system and a number of CCITT defined 192 kbit/s PCM lines, employing 2B+D, connected to an Integrated Services Digital Network (ISDN) exchange employing one of the following integrated networking protocol types: DPNSS/DASS or ISDN. Per DTU-BA seven trunk lines are available. The DTU-BA can operate either as Terminal Equipment (TE) or as Network Terminator (NT) in a network. Straps must be set to specify the TE or NT function:

- strap X4.1 is used for ISDN accesses 0 ... 2 or DPNSS circuits 2 ... 7;- strap X4.2 is used for ISDN accesses 3 ... 6 or DPNSS circuits 8 ... 15.

When changing over from TE to NT (or vice versa) also the projecting data has to be changed. Check the projecting data to see how the DTU-BA is projected.

• Terminal EquipmentWhen the DTU-BA is used as interface to the PSTN or another PBX it operates as a TE. It expects to receive an external clock reference from an NT to synchronise with. This means that a clock signal is available on frontconnector FC 101; this clock signal can be used as the input clock for a CRU, when necessary.One or both straps (X4.1 and/or X4.2) must be placed on positions 101-102.

• Network TerminatorWhen the DTU-BA is used as an NT, it operates as the master and it provides the synchronisation clock for the TE. This means that no clock signal is available on frontconnector FC 101.One or both straps (X4.1 and/or X4.2) must be placed on positions 102-103.

When two DTU-BAs form one transmission link (max. distance 1000 meters) one DTU-BA must be strapped as an NT and the other as a TE.

Note that ports 0...2 and port 3 are terminated on the FBA connector. Ports 4...6 are terminated at the FBB connector (see table below).

6.7. DTU-VC

The DTU-VC compresses a 64 kbit/s voice channel to a 16 kbps compressed channel. It is possible to send over one 64 kbit/s tie line three compressed voice channels, including framing and networking signalling.

Three of these compressed channels are combined on one DTU-VC line (64 kbps). There are 3 DTU-VC lines on a DTU-VC board, so a maximum of 964 kbps compressed voice channels can be handled via 3 DTU-VC 64 kbps lines.

The interface between the DTU-VC and up to three tie lines is provided by the TRunK board - Voice Compressed (TRK-VC). This TRK-VC is a plug on board and can be fitted onto a DTU-VC. When this board is used, the tie line interface can be selected (V.35 or G.703).

When the PPU software allows, the DTU-VC is able to use the loop back ports of the DTU-VC in order to use other ISPBX trunk ports. In this case the TRK-VC should not be installed.

The connection between two DTU-VCs can be made in two ways:

• Loopback Connection(without the TRK-VC)In this case the loopback channel is used and an existing digital route is used to transfer the 64 kbps channel(s) containing the 3 voice channels. This application uses other digital boards of the ISPBX to make a DTU-VC / DTU-VC connection. In this case the loopback channel is used to feed the 3 compressed voice channels to the backpanel as one 64 kbps channel.If the plug on board TRK-VC is absent this loopback is automatically made.

• TRK-VC ConnectionUsing the TRK-VC, which is a board plugged on the DTU-VC: this makes it possible to connect (G703 or V.35) 64 kbps tielines (DTU-VC lines). When the TRK-VC is present, the loopback line is de-activated. The connection in between the two DTU-VCs should be point-to-point.

• Interface between the TRK-VC and the Tie linesThe connectors to the external lines are on the TRK-VC card. For some pins, the signals on the connector depends on the type of interface selected (V.35 or G.703). The connectors which can be reached at the front side, are three 16-pin connectors, located at the positions FAA, FAB and FAC. Position FAD is not present. The allocation of the pins is given in figure.To receive the reference clock signals there are two possibilities (depending on the straps of X4.2 on the DTU-VC):- The clock received via trunk 1 is always taken as the reference clock. This means that

• Clock Reference OutputWith the used voice compression and multiplexing techniques, frame slips could be noticeable. Therefore it is important that the ISPBX is synchronised with the network. For this purpose, a coaxial connector is accessible from the front of the DTU-VC. It provides a 2.048 MHz clock reference output.The clock reference output is derived from the network supplied clock which is taken from the a tie line (64 kbit/s). Depending on strap setting, this can be tie line 1 or the tie line which is used for the signalling. It is advised to select tie line 1 as clock reference source. The clock reference output may be connected to the appropriate SOPHO card to synchronise the ISPBX to the network clock. The clock reference signal is never used when the TRK-VC board is not fitted.

6.8. DTU-G

The Digital Trunk Unit Generic (DTU-G) can operate as a DTU-PU or a DTU-PH installed in all iS3000 systems with the exception of a SOPHO S2500 system or in (R)PM2500 shelves.Before the DTU-G is installed in a system, the protocol mode must be selected by means of the dipswitch (S1.1 till S1.3) on the board.

• Line CharacteristicsThe characteristics of the line interface on the LTU-F are according to the CCITT recommendations G.703. The maximum cable length between to LTU-Fs depends on the loss factor of the glass fibre. The maximum allowed loss between two LTU-Fs is 24 dB.If a cable is used with a loss of 0,5 dB/km and a reserve of 5 dB is assumed, the maximum cable length will be 38 km. The reserve of 5 dB can be necessary to assure proper operation. If no reserve factor is taken into account, the maximum cable length is 48 km (loss factor of 0,5 dB/km).The LTU-F is connected to a DTU by means of cable and at the line side directly connected to a glass fibre cable. The DTU cable is plugged in at a front connector on the LTU-F carrier board. The glass fibre connectors are positioned at the LTU-F unit which is mounted at the carrier. The connectors are accessible at the front side.The interface to the DTU is a balanced (symmetrical) 120 ohms interface with a wiring for alarm signalling.

8. METERING CIRCUIT AND EMERGENCY SWITCH-OVER UNITS

The Metering Circuit (MC) is used to detect the metering pulses from the public exchange and to pass the metering information on via the Analogue Trunk Unit (ATU) to the Peripheral Control.

The metering circuits are also available in combination with the Emergency Switch over Units, the so called MCE boards.

8.1. MC(E)-D (16 circuit version)

The MC(E)-D (16 circuit version) is used to detect the 12 kHz metering pulses sent by the public exchange.

The sensitivity of the MC(E)-D board can be selected (using strap X3.1) to match the electrical specifications of the metering pulses as defined by the local PTT; see table below.

Table 8-1 Strap Settings MC(E)-D

8.2. MC(E)-F

The MC(E)-F board contains 16 metering detection circuits to detect the 16 kHz metering pulses sent by the public exchange.

The sensitivity of the MC(E)-F board can be selected (using strap X3.1) to match the electrical specifications of the metering pulses as defined by the local PTT; see table below.

8.4. ESU-LG

The ESU-LG contains 16 Emergency Switch Over circuits. In case of system failures (e.g. power down) the ESU connects a trunk line (with Subscriber Signalling) directly to an internal line. When the operational state is restored, the lines that are busy are guarded by the loop circuit and held in the emergency state. This prevents a busy line to be disconnected when the system becomes operational again. When the line becomes free, the extension is connected to the ALC and the trunk line to the ATU. This loop guarding option can be disabled by putting strap X1.1 on position 102-103.

11. INTEGRATED ANNOUNCEMENT SERVER

The Integrated Announcement Server (IAS) is a printed wiring board in an ISPBX shelf, providing announcements to applications like ACD and 'announcements on incoming trunks'. The IAS is controlled by the ISPBX CPU. Control information is exchanged between the CPU and the IAS via an IMP channel. Time slot 0 of the USO/USI interface of the IAS is used for IMP communication. Timeslot 1 is used for recording or listening to the announcements. The IAS has a direct connection to the Switching Network via a cable to an SCU or to an INC.

The Integrated Announcement Server - Autonomous (IASA) is based on the same hardware as the IAS board. The firmware differs between the IAS and the IASA and therefore the functionality. The IASA must be projected as a DLC-C board (14 or 30 ports) in the Unit Group. In contradiction to the IAS board, it cannot have a direct connection to the Switching Network although a connector for this purpose is present.

• Front Connector FACThe connection between the IAS and the Switching Network is done via front connector FAC. The IASA does not use this front connector but uses the USI/USO interface of the back panel. Strap X3.2. (see below) is used to select which interface is to be used.

• Front Connector FCCThere is V.24 circuitry on the IAS circuit board; it is accessed via front connector FCC. Standard bitrates from 300 to 9600 are permitted. The V.24 connector is intended for connection of a PC that is running IAS Download software or IAS Manager software. Connection can be made directly to front connector FCC or via a dialled connection using a LAM and SOPHO-SET.

• Strap X 3.1.The IAS circuit board is normally supplied with the NiCad batteries fitted but with the charging circuit disconnected. This ensures that the batteries retain their fully charged state while the circuit board is being transported or while it is not in use.Before the board is put into use, the charging circuit must be connected, so the battery charge is continuously maintained.

• Strap X 3.2.Strap X3.2. is used to select which interface is to be used.

-Batteries connected : Strap on position 101/102 (normal operation);-Batteries disconnected : Strap on position 102/103

-SCU/INC interface from connector FAC (IAS) :

Network.

The PMC-HR can be extended with an optional plug-on board for either two analogue operator interfaces (AOC) or one digital operator interface (DOC).

There is no clock regeneration circuitry for connecting to a DTU; therefore the PMC-HR can not synchronise to an external clock source.

• Interface between PMC-HR and Switching NetworkThe PMC-HR is connected to the Switching Network (SCU or SNS) via the front connectors FCA ... FCD. The table below shows the NIC data streams and the relevant signals that appear on the front connectors. A PMC-HR has two NICs available on each front connector but an SCU has only one NIC on each front connector; it is therefore necessary to use a split cable for the connection of the two cards. One split cable may not be connected to front connectors that are on two different SCU cards.

The PMC-G is able to control via the PM bus, 8 unit groups for all kinds of PCTs (UG0...7, 2 boards per UG) and 2 unit groups for PCTs without control data (UG8 and 9, 1 board per UG).

The PMC-G provides several basic telephony functions used to set up, maintain and release calls. All these functions are for common use.

The following basic telephony functions are provided on the PMC-G :

- 32 tone sources: - 16 tone sources are reserved for DTMF signals, compliant with CCITT

recommendation Q.23, and- 16 tone sources are free for customer projecting.

- 6 key tone receivers (RKT) : circuits 2, 3 & 4 and 7, 8 & 9.- 4 dial tone receivers (RDT) : circuits 5 & 6 and 10 & 11.- 32 three-party conference circuits (Add-On / Break-In circuit).- Peripheral switching network.- Protocol Co-Processor (PCP) providing 16 channels for Internal Message Protocol or

HDLC communication. Two of those 16 channels are reserved for CPU-PMC communication.

Clock (re)generation

The clock (re)generation circuit can operate in 2 different modes: master mode and slave mode.

In master mode the clock circuit either generates an internal clock signal or synchronises to an external clock signal. Two external clock inputs are available. The frequency of the external clock can be 2048 or 512 khz. A PMC-G operating in master mode can supply clock (2048 khz) and frame synchronisation signals for a second (slave) PMC-G or PMC-MC.

In slave mode the clock circuit either generates an internal clock signal or synchronises to a clock signal, received from another PMC-G, a PMC-MC or Switching Network via the network interconnection. Two network-clock input-signals are available. In an iS3070 or iS3090 system the clock circuit is always in slave mode.

A clock guard circuit continuously monitors the regenerated clock signal and the external clock inputs. Alarms are reported to software and used by hardware for autonomous clock source selection. The final selection of one of the clock sources is done by OM command ASCRUE.

The two clock signals are available via two coax connectors at the front : the top connector corresponds with PMC circuit 20 and the bottom connector with circuit 21.

Page 187: Mnp3810eMaintenance Part3-Board Interface & Strap

183

Operator Interface

The PMC-G has an on-board S0 interface (PMC circuits 0 & 1, only circuit 0 is used) dedicated for one operator console : a SuperVisor 25 or 35. The interface can not be used for other purposes.

Signalling group 7D04 has to be assigned to the operator interface : PMC circuit 0.

Network Connection Card

• Network Connection Card - Medium extended and interConnectable (NCC-MC)On the NCC-MC an interface circuit is present for connection to another PMC-G, PMC-MC or to a CSN-BC of an iS3030 or iS3050 system. This interface is on basis of 4 Mb/s and the maximum number of 4 Mb/s network interfaces is 6. On the NCC-MC each 4 Mb/s network interface is demultiplexed and multiplexed into two 2 Mb/s signal to and from the mother board.The NCC-MC has 4 F122 connectors (FAA ... FAD).- FAA : master 1- FAB : master 2- FAC : slave 1- FAD : slave 2The cables must be plugged into positions, which comply with the master or slave status of the PMC-G.In case of the link to the CSN-BC the slave positions have to be used.

• Network Connection Card - High Range (NCC-HR)On the NCC-HR an interface circuit is present for connection of the peripheral switching network to the Switching Network of an iS3070 or iS3090 system. This interface is on basis of 2 Mb/s and the maximum number of these 2 Mb/s Network interfaces is 8.Those 8 interfaces are available on 4 F122 connectors : FAA ...

14. CPU3000 / VIC3000

Some external devices can be connected on the CPU3000 of the SOPHO iS3000 series and SOPHO-S250/1000. The total number of V.24 device ports on the VIC3000 is limited to 6 when no Ethernet is available and 5 when the Ethernet connection is used on the CPU3000. The Ethernet port of the CPU3000 is half duplex.

In addition, there is a V.28 connection for alarming.

The V.24 ports are available on the VIC3000 daughter board. The numbering of the VIC3000 ports starts at the top. The lowest socket of the VIC3000 has no function and has no number.

There is a Vanadium Lithium battery fitted on the CPU3000 board.

- in an operational system strap X12.4 must be placed on position 102/103: battery connected.

- to prevent the complete unloading of the battery while the circuit board is being transported or while it is not in use strap X12.4 must be placed on position 101/102 : the charging circuit is disconnected.

The battery has a life-span of 7 years after which it must be replaced.

15. COMMUNICATION INTERFACE EXTERNAL

15.1. CIE

The Communication Interface External (CIE) is an interface between the CSM Bus of the iS3070/3090 and the backup and Interface Module (BIM).

To communicate with the BIM a fast IEEE802.3 Ethernet interface is used. The Ethernet port of the CIE is half duplex. An RJ45 front connector is provided for a twisted wire (10BASE-T) connection to the BIM. The maximum length of this Ethernet cable is 100 meters.

Front connectors FCA ... FCD provides the interface of the 13 inputs and 10 outputs of the Switch and Sense Unit on the CIE.

It is possible to install a second CIE (or more) to obtain a more fault tolerant system (a BIM has to be connected to each additional CIE).

17. POWER SUPPLY UNIT

17.1. PSU-MLD(02)

The Power Supply Unit-Medium Large Direct current (PSU-MLD or PSU-MLD02) is used in the PM1100 or PM255. The PSU-MLD(02) converts the -48V dc input voltage to +5V, -5V, +12V, -12V, 4VBAT, VCMOS and ringing output voltages. The PSU-MLD(02) can be strapped for 75V ac or 60V ac ringing voltage and 25Hz or 50Hz ringing frequency. There are five -48V dc outputs on the back panel.

Note: The ringing output voltage for the PSU-MLD used in CHINA (type number 9562 002 0200) has changed from 75 volts to 82.5 volts. This change does not apply to the rest of the world.

The difference between the PSU-MLD and PSU-MLD02 is an extra -60Vdc signalling voltage on the PSU-MLD02.

• StrapsStrap X1.1 is used to select the ringing frequency:- strap on 101-102 : 25Hz;- strap on 102-103 : 50Hz.Strap X1.2 is used to select the ringing voltage:- strap on 101-102 : 60V;- strap on 102-103 : 75V.

• Fuses and Leds

If any of the fuses on which there is a load, is blown, the relevant LED lights and an alarm is activated. Boards that have an on board power converter (like for example the DTX-I) will not cause such an alarm.Both the PSU-MLD and PSU-MLD02 have an extra 'PSU OK LED' indicating that all output voltages are within the tolerances.If the voltages are not within the tolerances, the 'PSU OK LED' will switch off and an alarm is activated.

PSU-MLD : there are five fuses (3, 15 A) with LEDs on the front panel; they are for the - 48V circuits supplied to the back panel.

PSU-MLD02 : there are six fuses with LEDs on the front panel. Five fuses (3, 15 A) with LEDs are for the - 48V circuits supplied to the back panel. The extra fuse (3, 15 A) with LED is for the - 60V signalling voltage.

The front connectors are not relevant anymore.
