SYSTEM RACK

4-10

PTM Switch Settings

Verify the switch settings of the Power Termina-

tion Module (PTM) are as follows:

S5, S7 section 1 closed;

sections 2,3,4,5,6,7,8 open

S6, S8 sections 1,2,6 closed;

sections 3,4,5,7,8 open

Call Processor Connection To Switch

Verify the Call Processor connection to the

System rack as follows:

1. NetIDB Connection: Use the 20’ RS-232 cable to

connect Shelf 1-J100 to Port 1 of the Call Processor
computer.

2. NetCSB Connection: Use the 20’ RS-232 cable to

connect Shelf 1-J101 to Port 2 of the Call Processor
computer.

3. Install a Power Termination Module in the first slot

on the left side of each shelf.

4. Install the NetNIM in Shelf 1, Slot 0.

5. Turn "On" both Power Supplies, turn "On" the Call

Processor and note that the four LEDs on each PTM
card are "On".

a. Verify that the Call Processor comes up in the

Switch mode.

b. Verify that the Call Processor displays the Net-

NIM’s clock status, "A Pass B Pass" in the Call
Processor’s Device Activity window. If neces-
sary, press the reset button S1on the NetNim to
activate the clock status.)

PCM Bank Verification

PCM Bank Verification requires two Channel

Interface Modules (CIMs).

1. On both CIMs place a patch cord from the top jack

of J1 to the top jack of J2 (see Figure 10-1).

2. Close S1, sections 3-4; open sections 1-2 on each

module.

3. On both CIMs set switch sections as follows:

Switch

Section

S3

1-2 open; 3-4 closed

S4

1-2 closed; 3-4 open

S5

1-2-3-4 closed.

4. Set one module for System Test "5"

(S5-sections 1 and 3 open; sections 2 and 4 closed).
Place this module in any slot on Shelf 1.

5. Set the second module for System Test "6".

(S5-sections 2-3 open; 1-4 closed). Place this
module in any slot on Shelf 4.

6. Loop Primary Tx PCM to the Primary Rx PCM by

connecting a cable (023-3039-842) from Shelf 1-J3
to Shelf 1-J4 (see Figure 4-5).

7. The modules display an "A" if the PCM bank is

good. Press S2 to reset the module if "A" is not
displayed.

A failure on the primary displays a "1" on one or
both modules.

A failure on the secondary displays a "2" on one
or both modules.

8. Repeat this procedure by moving the module on

Shelf 4 to Shelf 3. Reset both modules if “A” is not
displayed.

9. Repeat this procedure by moving the module on

Shelf 3 to Shelf 2. Reset both modules if "A" is not
displayed.

10.After the PCM bank has proven good, force failures

on both the primary and secondary as follows:

Primary

Remove cables on Shelf 1, J5 and J6.

A "1" on both modules indicates a Primary
failure.

Reconnect the cables.

Secondary

Remove cables on Shelf 1, J23 and J24.

A "2" on both modules indicates a Secondary
failure.

Reconnect the cables.

Remove the cable from Shelf 1, J3 to J4.
