Peripheral Switching Module(PSM)Peripheral Switching Module(PSM)---- ---- Structure of the PSM
FBI(Fiber Bus Interface) It applies synchronous multiplexing technique and optical fiber
technique to implement the interconnections of Modules .
It uses two optical fiber lines to transmit up to 16 lines of 8Mb/s PCM signals
It can reduce connection wires and increase anti-interference ability of the system, and to reduce mutual cross talks among wires. These enable the PCM wire signals in T network to be correctly.
Note : When HW lines 4~19 are used for intra-module unit
connection,the FBI board must be replaced by the DSNI.

Compact switching module(4k)Compact switching module(4k)
Typical configuration : single processor cabinet : 2400L+600DT
double processor cabinet : 5280L+600DT
Network principle :1.Form exchanges independently ;
2.Used as peripheral remote modules to access the central module. Normally, they are not used as nearby module,but merely as network terminal nodes.
3.Normally not carry any lower level switching modules further down,or RLM(unless there are enough trunks)

RSU---- RSU---- Instruction of RSU
MTT (multi-task test)board:
---used also as the DTMF number receiver and TONE voice resource.
REPD board:
----control the power board and ODT board
----clock synchronization for RLM.
RSU---- RSU---- Question
Q1.what will be paid attention to when using RODT to connect RSU?
1) Add “RODT” when configuring the transmission shelf for RSU;
2) For the RODT of host office, at maximum 2 8M HW can be configured for every board;
3) When configuring subscriber unit of RSU, the corresponding HW line connection between host office and RSU can be created;
4) If in step2 ,more than 2 8M HW are assigned,the step 3 can not continue.
