Procedure for Shelf 1
NOTE
:
This procedure should be performed for shelf 1 which will be directly con-
nected to the telemetry system.
1. Obtain a parallel telemetry cable Group 362 or 363 (refer to Table 2-4).
2. Connect the cable to P54 of shelf 1.
3. Route the parallel telemetry cable out of the DDM-2000 OC-3 bay per Fig-
ure 2-12 to the telemetry system, stacking the cables as shown in Figure
2-2 or Figure 2-3.
4. Dress and tie the cables in the bay and as close to the DDM-2000 OC-3
backplane as possible without touching any backplane pins.
5. Cut the parallel telemetry cable to the desired length at the telemetry panel.
6. Wire-wrap the loose end of the parallel telemetry cable to the telemetry
system, making connections as shown in Table 2-9.
Procedure for Other Shelves
NOTE
:
This procedure should be performed when shelf 1 in the bay is connected
to the parallel telemetry system. The cable added in this procedure is to
mult parallel telemetry from other shelves in a bay to shelf 1. In this proce-
dure shelf 1 will be connected to shelf 2, shelf 2 will be connected to shelf
3, etc.
NOTE
:
For parallel telemetry in shelves other than shelf 1 to report, all parallel
telemetry cable mults from that shelf to shelf 1 must be in place. No shelf
should be skipped.
1. Obtain a parallel telemetry cable Group 364 or 366 (refer to Table 2-4).
2. Connect the cable to P54 of the shelf.
3. Route the cable to the side of the bay and down and connect it to P55 of
the shelf below as shown in Figure 2-12.
4. Dress and tie the cables in the bay as close to the backplane as possible
without touching any backplane pins.
5. Repeat Steps 1 through 4 for each shelf in the bay.
