Cutover Procedures for Out-of-Service Equipment
If DDF access jack sets
are not
cabled to the ESCIU module, the
following out-of-service cutover procedure must be used. Consult
the local company Installation Job Specifications to ensure that
the network element to be retimed is connected to the ESCIU
module correctly. Refer to Figure 31 for the following procedure:
1. Remove from service (turn down) the traffic trunks on the E1
system to be cutover to the ESCIU module.
2. Remove the existing cabling in both directions between the
transmit (OUT) and receive (IN) terminals of the NEs that will
connect to the ESCIU module.
3. In the direction not to be synchronized by the ESCIU module,
connect new cables from the ESCIU module RTNx IN connector
to the NE transmit (OUT) terminal, and connect from the ESCIU
module RTNx OUT connector to the NE receive (IN) terminal.
4. In the direction to be synchronized by the ESCIU module,
connect new cables from the ESCIU module IN connector to the
NE transmit (OUT) terminal, and connect from the ESCIU
module OUT connector to the NE receive (IN) terminal.
5. Verify that there are no alarms on the NEs on the E1 system. If
there are alarms, recheck the new cabling between the NEs and
the ESCIU module.
Note:
If the TimeSource 3600 is still in warm-up or searching for GPS
satellites, alarms may be present. All synchronization-related alarms
should clear while the TimeSource 3600 is in steady-state operation.
6. Restore (turn up) the traffic trunks to service.
