SYSTEM RACK

PTM Switch Settings

Verify the switch settings of the Power Termination 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.
