Replace Release 9r circuit packs

Administering the sync source
NOTE:
Do not administer a trunk on the SREPN as the synchronization source for
the Release 9r. If the system goes into the survive mode, the Release 9r
loses its sync source.
To administer the sync source for the SRP:
1. On the SRP system, type change synchronization and press
2. Enter a DS1 trunk circuit pack on the SRP as the primary sync source.
3. Press
4. When all administration is completed on the SRP, type save translation
and press
5. Return the TN2301 switch to the AUTO position.
Replace Release 9r circuit packs
If the Release 9r has the TN574 DS1CONV circuit pack:
1. Replace the TN574 DS1CONV circuit pack with the TN1654 DS1CONV
circuit pack.
2. If you have a TN573 SNI circuit pack, replace it with a TN573B SNI circuit
pack.
to effect the changes.

NOTE:
When the system is in the survive mode, the synchronization of the
SRP comes from the DS1 trunk circuit pack. When the system is in
the normal mode, the synchronization of the SRP reverts back to the
tone clock and causes a sync alarm in the alarm logs of the SRP.
