Shelf S1 Switch Settings
Verify switch settings of S1 in Table 4-15 for
each shelf address (see Figure 4-5).
Backplane Switch Settings
Verify the backplane switch settings for S2 - S8
on each shelf are set with all sections closed.
PTM Switch Settings
Verify the switch settings of the Power Termina-
tion Module (PTM) are as follows:
S5, S7 all sections closed;
S6, S8 section 8 closed;
sections 1, 2, 3, 4, 5, 6, 7 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 2.
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).
