Equipment and Rear Access Cable Installation
NOTE
:
In order for office alarms in a shelf (other than shelf 1) to be reported, all
office alarm cable mults from that shelf to shelf 1 must be in place. No shelf
should be skipped.
1. Obtain an office alarm cable Group 359 or 361 (refer to Table 2-5).
2. Connect the cable to P56 of the shelf.
3. Route the office alarm cable to the side of the bay and connect it to P57 of
the shelf below as shown in Figure 2-12.
4. Dress and tie the cables as close to the backplane as possible without
touching any backplane pins.
5. Repeat this procedure for each shelf in the bay.
Parallel Telemetry Cable Installation -
Rear Access
NOTE
:
Parallel telemetry is not available in Release 13 software.
Description
Parallel telemetry provides a set of alarm and status outputs in the form of contact
closures which can be reported to a maintenance center through a telemetry
system. Connection of parallel telemetry requires a parallel telemetry system in
the office, and thus parallel telemetry is only used in a central office environment.
Perform this procedure if specified in the order.
Unless otherwise specified, shelf 1 (bottom shelf in the bay) should be cabled
directly to the parallel telemetry equipment. Additional shelves in the bay are
daisy-chained up from shelf 1. The shelf identification (SID) number for the
parallel telemetry is determined by the backplane wiring and the wiring
assignments within the mult cable. If shelf positions are skipped in a bay, then SID
numbers for shelves above the empty position will not match the shelf positions in
the bay.
NOTE
:
Parallel telemetry cable options are listed in Table 2-4.
NOTE
:
Parallel telemetry connections are listed in Table 2-9.
