Subscriber Lines.
Connect the subscriber lines:
You must use the cable adapter (PN 120-1111-01) to ensure the subscriber
terminations follow the information shown in Tables 14 and 15.
1
For PG-Flex system 1, use Table 14 to connect the CO switch cables to the cable adapters for
P1 and P3 terminations.
2
For PG-Flex system 2, use Table 15 to connect the CO switch cables to the cable adapters on
P2 and P4 terminations.
8.8
Auxiliary Power Pairs.
When PG-Flex is used with a doubler, wire the COT shelf:
1
Wire-wrap auxiliary power pair 1 to PWR_OUT_T1 (Tip) and PWR_OUT_R1 (Ring) for
system 1.
2
Wire-wrap auxiliary power pair 2 to PWR_OUT_T2 (Tip) and PWR_OUT_R2 (Ring) for
system 1.
3
Repeat steps 1 and 2 when required for systems 2.
8.9
Fuse.
Insert a 6 amp fuse in the equipment bay fuse panel for the circuit where the PG-Flex CO
battery wire is terminated.
8.10
Cabling Verification.
Verify the following:
The following verifications should be done before any cards are inserted in the
COT shelf.
1
Verify a minimum of -42 Vdc and a maximum of -56 Vdc between TB1 (–48 Vdc) and TB2
(BATT RTN) screw terminals on the COT shelf.
2
Verify the following for the HDSL lines:
If the HDSL lines are not connected properly, the COT will not communicate
with the RT.
a
Visually verify the HDSL lines are terminated properly and with the correct orientation.
b
Verify that the HDSL lines are "dry."
c
Verify 0 Vdc between the Tip and Ring, Tip and Ground, and Ring and Ground of each of
the HDSL circuits terminated on the shelf.
d
Verify > 100 k
Ω
resistance between the Tip and Ring, Tip and Ground, and Ring and
Ground of each of the HDSL circuits terminated on the shelf.
3
Replace the clear Plexiglas cover on the rear of the COT shelf.
9. Turn-Up and Testing
9.1
Refer to the COT or RT Line Unit Technical Practices for complete COT and RT turn up and
testing procedures.
