4.1 PDH Interface Board

On the board panel, “A” in the bar code indicates the 75 ohm board in the

interface, and “B” in the bar code indicates the 120 ohm board in the

interface.

E1/E3 signal is in the HDB3 code. T1 signal is in B8ZS or AMI code. DS3

signal of the interface is in B3ZS code.

On the board front panel, there is no connector, and the electrical signal

must be accessed in conjunction with the C12/C34S or C34/C34S.

There is an indicator in the PDH interface board:



Internal Use Only

If the indicator is On (green), the board is configured with the data and

is in the operation status.

If the indicator is Off, the board is not configured with services or is in

the protection status.

When the PL3 board is configured with the TPS, E3/DS3 signal input and

output must be completed in conjunction with the C34S and TSB3 boards.

4.2 Electrical Interface Commutator

The C12 completes E1/T1 electrical signal conversion function together with

PL1D, PL1S, PM1D, PM1S, PF1D, and PF1S. When the TPS protection is

configured, C12S must be used. When the TPS is not configured, C12S can

be used together with the C12.

C34S board is the 3-channel E3/DS3 signal commutator, and completes

E3/DS3 electrical signal conversion together with the PL3. When the

equipment is configured with the TPS protection, the C34S board can be

inserted in Slot 24, 25, 30 and 31 (When Slot 26 and Slot 32 are inserted

with the TSB3, E3/DS3 signal TPS function must be completed together with

the TSB3). When the equipment is not configured with the TPS protection,

C34S board can be used as the signal commutator, and inserted in Slots

24,25,26,30,31,32. Schematic diagrams of C12S, C34S and TSB3 are

Figure 1-9 C12S board principle

Take 1-channel E1/T1 signal input and output as an example to introduce

C12S board working principle:

In the normal status, the switch is toggled to the working position of E1/T1

electrical interface board bus. When the switching event occurs, the switch is

toggled to the protection position of E1/T1 electrical interface board bus.

Figure 1-10 C34S board principle

Take 1-channel E3/DS3 signal input and output as an example to introduce

C34S board working principle:

Receiving direction:

Normally, the E3/DS3 signal from the cable is input to the PL3 board of the

working slots (Slot 4, 5, 10 and 11) after the switch control module.

When the equipment detects the TPS switching event, the E3/DS3 signal

from the cable is switched to the protection bus in the switch control module,

and is sent to the TSB3 board of Slots 26 and 32.

Transmitting direction

Normally, the E3/DS3 signal output from the PL3 board of the working slots

(Slot 4, 5, 10, and 11) is output to the cable through the switch control

module.

When the equipment detects the TPS switching event, the switching occurs

in the switch of the switch control module. Now the power control module

receives the E3/DS3 signal sent from the TSB3 (from Slot 26, 32) from the

protection bus, and the signal is output to the cable.

Internal Use Only

Take 1-channel E3/DS3 signal as an example to introduce the principle of

the TSB3.

Receiving direction:

If the PL3 board in the Slot 5 or 11 is faulty, the E3/DS3 signal input from the

C34S board (in the Slot 25 or 31) is input to the PL3 board in Slot 6 or 12

through the switch control module.

If the PL3 board in the Slot 4 or 10 is faulty, the switching occurs to the

switch of the switch control module. The E3/DS3 signal input from the C34

board (in the Slot 24 or 30) is input to the PL3 board in Slot 6 or 12 through

the switch control module.

Transmitting direction:

If the PL3 board in the Slot 5 or 11 is faulty, the E3/DS3 signal output from

the protection slots (Slot 6 or 12) is sent to the C34S board in Slot 25 or 31


If the PL3 board in the Slot 4 or 10 is faulty, the switching occurs to the

switch of the switch control module. The E3/DS3 signal output from the

protection slots (Slot 6 or 12) is output to the C34S board in Slot 24 or 30


4.3 10M/100M Ethernet Electrical Interface Board

ET1D provides the access, transparent transmission and switching of 2-

channel 10M/100M Ethernet signal service. For the note of working principle

and deployment in detail, see the guide to the board deployment.

4.4 SDH Interface Board

The OSB1 is 155M optical interface board, and integrated in the XCS board

(in this case, the board name is XCS1). The OSB4 is 6222M optical interface

board, and integrated in the XCS board (in this case, the board name is

XCS4). The SL1 is 155M optical interface board, and the SD1 is 155M dual

optical interface board. SL1/SD1 can be inserted in Slot 10 and 11. Table 10

describes the standard and parameters of the corresponding optical

interface.

4.5 System Control & Communication Unit (FSCC)

The FSCC provides up to 6-channel DCC processing capability, and is

located in Slot 3. Metro 1050 NE ID can be set through command line.

During the deployment and commissioning, the DIP switch of the FSCC

should not be set, and the factory default setting is recommended. The NE

ID and IP can be set through the command lines.

4.6 Cross Connection/Clock Integrated Unit (XCS)

The XCS1 is integrated with the cross connection and clock unit of the

OSB1. The XCS4 is integrated with the cross connection and clock unit of

the OSB4. The XCS/XCS1/XCS4 is inserted in Slot 7 and Slot 8 (They are

shown as Slot 17 and Slot 18 in the network management system). The XCS

provides board temperature detection, main control service data backup,

and board 1+1 hot backup to complete the service scheduling function. The

XCS only supports space division cross connection, and does not support

time division cross connection.

4.7 Synchronous Clock Interface Unit

STIA/STIB applies for type I equipment (A refers to 75 ohm interface and B

refers to 120 ohm interface). STIC/STID applies for type II equipment (C

refers to 75 ohm interface and D refers to 120 ohm interface). For A/C

interface, see the board silkscreen. B/D is DB9 interface. Definitions of pins

are as follows:

4.8 Order Wire Processing Board

The order wire processing board is in Slot 9, and completes the RS-232 data

broadcast interface of 1-channel order wire phone (supporting addressing

call and meeting call) and 4-channel transparent transmission. The

maximum rate of data broadcast interface is 19.2kbit/s (it can also be used

as 3-channel Boolean to input -S1/S2/S3 and 1-channel Boolean to output –

S4). The order wire interface is RJ11. S1-S4 adopt RJ45 interface. The order

wire works in DTMF mode, and uses E1/E2 byte. S1/S2/S3/S4 interface

respectively uses X1/X2/X3/F2 bytes.

Note

Metro 1050 system does not provide the order wire outgoing subnet

connection function.
