NOTE

l All DIP switches are on the front panel of the sub-board. The front panel is combined with the bottom plate, so the DIP switches are not exposed.

l DIP switches S2, S4, S6, S8, and S10 are set from the side. As shown in Figure 6-2 , there are two

square holes between DIP switches, one between S2 and S4, and the other between S8 and S6. Throughthe two holes, you can set S2, S4, S8, and S6. DIP switch S10 is located in the right corner of the sub-

board, and thus you can set S10 along the side. The direction of the arrow in Figure 6-2 is to turninwards. To set the bits of S2, S4, S6, or S8 to ON, turn them inwards. To set the bits of S2, S4, S6, or S8 to OFF, turn them outwards. To set the bits of S10 to ON, turn them outwards. To set the bits of S10 to OFF, turn them inwards.

l You can also run the SET E1T1 command on the LMT to set S10. If there is any inconsistency betweenthe physical setting of S10 on the AEUa board and the setting of S10 by command, take the setting bycommand as the criterion. By default, the working mode of S10 is set to E1. You can also run the SETE1T1 command on the LMT to change the working mode of S10 from E1 mode to E1 balanced mode,E1 unbalanced mode, or T1 mode. When you run the SET E1T1 command to set the support for

balanced and unbalanced modes parameter to No and set the working mode of S10 to E1, you mustalso manually set the bits of S10 to set the working mode of S10 to E1 balanced mode or E1 unbalanced

mode.l If signals are transmitted in E1 unbalanced mode, the signals are transmitted through the 75-ohm coaxial

cable and the TX end of the cable is grounded, that is, the corresponding DIP bit is set to ON. If signalsare transmitted in E1(T1) balanced mode, the signals are transmitted through the 120-ohm twisted pair cable and the TX end of the cable is not grounded, that is, the corresponding DIP bit is set to OFF.

Description of the DIP Switches

DIP switches S2, S4, S6, and S8 on the AEUa board are used to enable or disable the groundingof 0 to 31 E1s/T1/J1s at the TX end. DIP switch S10 is used to set the working mode to E1

balanced mode, E1 unbalanced mode, T1 mode, or J1 mode. Table 6-4 describes S2, S4, S6,S8, and S10.

l You can also run the SET E1T1 command on the LMT to set S10. If there is any inconsistency betweenthe physical setting of S10 on the PEUa board and the setting of S10 by command, take the setting bycommand as the criterion. By default, the working mode of S10 is set to E1. You can also run the SETE1T1 command on the LMT to change the working mode of S10 from E1 mode to E1 balanced mode,E1 unbalanced mode, or T1 mode. When you run the SET E1T1 command to set the support for

balanced and unbalanced modes parameter to No and set the working mode of S10 to E1, you mustalso manually set the bits of S10 to set the working mode of S10 to E1 balanced mode or E1 unbalancedmode.

l If signals are transmitted in E1 unbalanced mode, the signals are transmitted through the 75-ohm coaxialcable and the TX end of the cable is grounded, that is, the corresponding DIP bit is set to ON. If signalsare transmitted in E1(T1) balanced mode, the signals are transmitted through the 120-ohm twisted pair cable and the TX end of the cable is not grounded, that is, the corresponding DIP bit is set to OFF.

DIP switches S2, S4, S6, and S8 on the PEUa board are used to enable or disable the groundingof 0 to 31 E1s/T1s/J1s at the TX end. DIP switch S10 is used to set the working mode to E1

7.3 Optical Cable

The optical cable is optional in the BSC6900. It is used to connect the optical interface board tothe Optical Distribution Frame (ODF) or other NEs. The number of optical cables to be installeddepends on the site requirements.

Classification of the Optical Cable

According to the types of optical connectors at both ends of the cable, the optical cable can beclassified into the following types:l LC/PC-LC/PC single-mode/multi-mode optical cablel LC/PC-FC/PC single-mode/multi-mode optical cablel LC/PC-SC/PC single-mode/multi-mode optical cable

NOTE

l In actual installation, the LC/PC optical connector at one end of the cable is connected to the opticalinterface board in the BSC6900, and the connector type at the other end of the cable depends on siterequirements.

l The L C/PC-LC/PC single-mode/multi-mode optical cable connects the optical interface board to theODF or other NEs or connects the optical interface boards.

l In practice, two optical cables form a pair. Both ends of each cable in the pair are attached withtemporary labels. If one end of the cable is connected to the TX port, the other end should be connectedto the RX port.

CAUTION

The TX end and RX end of each optical cable must be connected correctly. Otherwise, the opticalsignals cannot be received or transmitted.

Figure 7-10 Optical splitter/combiner

Classification

The optical splitter/combiner can be classified into the following types according to the modein which optical signals are transmitted:

l Single-m ode optical splitter/combiner: The optical fiber of the single-mode optical splitter/combinter is yellow.

l Multi-mode optical splitter/combiner: The optical fiber of the multi-mode optical splitter/combiner is orange.

Application Scenario

When optical interface boards work in active/standby mode and optical transmission devices

work in independent mode, optical splitters/combiners can be used to improve the redundancy performance of optical interface boards.



182



CAUTION

Only the AOUa, UOIa, AOUc, POUc, and UOIc boards can be connected to an optical splitter/

combiner.The optical splitter/combiner cannot be used to solve any of the following problems:l The active and standby optical ports on BSC6900 interface boards are operational. When the

transmission on the TX optical fiber for the active optical port is interrupted, the BSC6900reports a Multiplex Section (MS) Remote Defect Indication (RDI) alarm on the active andstandby optical ports. An automatic switchover, however, is not triggered between the activeand standby optical ports.

l The active and standby optical ports on BSC6900 interface boards are operational. Thetransmission is interrupted on the optical fiber between the optical splitter/combiner and theTX port on the peer equipment, and the BSC6900 reports a MS RDI alarm on the active andstandby optical ports. An automatic switchover, however, is not triggered between the activeand standby optical ports.

l The active and standby optical ports on BSC6900 interface boards are operational. Thetransmission is interrupted on the optical fiber between the optical splitter/combiner and theRX port on the peer equipment, and the BSC6900 reports a Loss of Signal (LOS) alarm onthe active and standby optical ports. An automatic switchover, however, is not triggered

between the active and standby optical ports.

9 DIP Switches on Components

About This Chap ter

This chapter describes the DIP switches on the boards and subracks of the BSC6900.

9.1 DIP Swit ch on the Subrack The DIP swit ch on a subrack is used to set the nu mber of the subrack.

9.2 DIP Swit ches on the AEUa BoardThe AEUa bo ard provides five DIP switches, name ly, S2, S4, S6, S8, and S10.

9.3 DIP Swit ches on the AOUa Board

The AOUa bo ard provides two DIP switches, both o f which are labeled S1. The two DIP switchesare used to set the mode of the two STM-1/OC-3 optical ports.

9.4 DIP Swit ch on the PAMU BoardThe PAMU p rovides an SW1 DIP switch.

9.5 DIP Swit ches on the PEUa BoardThe PEUa bo ard provides five DIP switches, namel y, S2, S4, S6, S8, and S10.

9.6 DIP Swit ch on the PFCU BoardThe PFCU bo ard has one DIP switch, which is named SW1 and consists of four bits. The DIPswitch is used to set the address of the PFCU board. When the PFCU board is configured in afan box of the service subrack, the address of the PFCU board is set to 1. When the PFCU board

is configured in the independent fan subrack, the address of the PFCU board is set to 4.

9.7 Pins on the PFCB BoardThe PFCB board provides eight pairs of pins for jumpers. After being connected to jumpers,these pins are used to set the address and working mode of the PFCB board. The settings of these

pins depend on the installation position of the PFCB board.

9.8 DIP Switches on the POUa BoardThe POUa board provides two DIP switches, both of which are labeled S1. The two DIP switchesare used to set the mode of the two STM-1/OC-3 optical ports.

Table 9-1 Description about the bits

Bit Description

1-5 Bits 1 to 5 are used for setting the subrack number. Bit 1 is the

least significant bit. If the bit is set to ON, it indicates 0. If the bitis set to OFF, it indicates 1.

6 Odd parity check bit

7 Reserved, undefined, generally set to ON


Startup type of the subrack, generally set to OFF

Principle of the DIP Switch Setting As the DIP switch uses odd parity check, the number of 1s in the eight bits must be an oddnumber. The method for setting the bits is as follows:

1. Set bit 1 to bit 5 as required.

2. Set bit 7 to ON.

3. Set bit 8 to OFF.

4. Check the number of 1s in the seven bits of the DIP switch.l If the number of 1s is even, set bit 6 to OFF.l If the number of 1s is odd, set bit 6 to ON.

Table 9-2 describes the setting of the DIP switch in the case.

NOTE





l You can also run the SET E1T1 command on the LMT to set S10. If there is any inconsistency betweenthe physical setting of S10 on the AEUa board and the setting of S10 by command, take the setting bycommand as the criterion. By default, the working mode of S10 is set to E1. You can also run the SETE1T1 command on the LMT to change the working mode of S10 from E1 mode to E1 balanced mode,E1 unbalanced mode, or T1 mode. When you run the SET E1T1 command to set the support for

balanced and unbalanced modes parameter to No and set the working mode of S10 to E1, you mustalso manually set the bits of S10 to set the working mode of S10 to E1 balanced mode or E1 unbalanced

mode.l If signals are transmitted in E1 unbalanced mode, the signals are transmitted through the 75-ohm coaxial

cable and the TX end of the cable is grounded, that is, the corresponding DIP bit is set to ON. If signalsare transmitted in E1(T1) balanced mode, the signals are transmitted through the 120-ohm twisted pair cable and the TX end of the cable is not grounded, that is, the corresponding DIP bit is set to OFF.


DIP switches S2, S4, S6, and S8 on the AEUa board are used to enable or disable the groundingof 0 to 31 E1s/T1/J1s at the TX end. DIP switch S10 is used to set the working mode to E1

balanced mode, E1 unbalanced mode, T1 mode, or J1 mode. Table 9-3 describes S2, S4, S6,S8, and S10.
