Operational Tests
7. Either:
a. Verify that the maintenance center has observed the alarm bit. If
the alarm bit indication is not observed by the maintenance center,
verify alarm telemetry wiring. Refer to Table 9-1 for wiring connec-
tion information.
or
b. The voltmeter should read 48 volts. If the alarm bit indication is not
observed at the office alarm interface, verify alarm telemetry wiring.
Refer to Table 9-1 for wiring connection information.
8. Verify that the correct SID indication is activated (that is, the SID indication
should be the same as the DDM-2000 OC-3’s shelf number) by entering
‘SID’ at the mode prompt. If the alarm bit indication is not observed by the
maintenance center or at the office alarm interface, verify alarm telemetry
wiring. Refer to Table 9-1 for wiring connection information.
9. Repeat the parallel telemetry test for each individual telemetry point.
Procedure Without a Terminal
NOTE
:
The proper SID setting should be verified for all telemetry points.
NOTE
:
This procedure verifies the following parallel telemetry points can be set in
the CO: CR, MJ,MN, ACO, CLF, INC and NE.
1. Unseat one service (positions 1 through 7) low speed circuit pack.
Activated telemetry points: MN, NE.
2. Unseat a second service low speed circuit pack in the same function group.
Activated telemetry points: MJ, NE.
3. Unseat a pair of function units.
Activated telemetry points: CR, NE.
4. Press the ACO pushbutton on the user panel.
Activated telemetry points: ACO, NE.
5. Reseat all circuit packs.
Activated telemetry points: None.
6. Connect a DS1 or DS3 input signal to the DDM-2000 OC-3. Remove the
input signal.
Activated telemetry points: INC, NE.
