SREPN Feature Active
!
WARNING:
Every call within the SREPN is terminated when the SREPN feature is
activated, and the R6si SRPPN takes control of the SREPN.
The SREPN feature is activated when the Maintenance circuit pack (TN775C or
later and located in the SREPN) detects a problem with the SREPN’s EI
(TN570B) LAP-D link to its counterpart in a S8700 Multi-Connect EPN. The
TN775C Maintenance circuit pack notifies the co-located SRPPN of the problem,
and the TN2301 SRSwitch circuit pack in the SRPPN carrier switches the EI
LAP-D link connection from the S8700 Multi-Connect PPN to its new counterpart
in the S8300 Media Server with G700 Media Gateway SRPPN. The SREPN is
now in the Survivable Remote mode and has the capabilities of an S8300 Media
Server with G700 Media Gateway EPN that has been pre-translated with a
Disaster Recovery configuration.
NOTE:
When SREPN feature is active, the EI circuit pack that is assigned to the
SREPN and located in the S8700 Multi-Connect PN is put in loop-back
mode.
Restoring Normal Service to the SREPN
!
WARNING:
Every call within the SREPN is terminated when the SREPN feature is
returned to normal service.
To restore normal connections to the SREPN EI circuit pack in the S8700
Multi-Connect PN, you must:
1. Clear every error logged against the S8700 Multi-Connect SREPN EI
circuit pack by using the suggested repair procedures outlined in this MO.
2. At the SRP flip the 3-position switch on the TN2301 to the RSTR (restore)
or top position for at least 1 second and return the switch to the AUTO, or
middle position.
3. After the SREPN slide switch has been restored to the normal position, test
the connectivity to S8700 Multi-Connect EI LAP-D link, by using the
suggested procedures outlined in this MO.
4. After normal service is returned to the S8300 Media Server with G700
Media Gateway SREPN, the SRPPN will be in an alarmed state. This is
normal for an SRPPN and indicates that the:
■
SRSwitch (TN2301) has disconnected it from its neighbor (EI in the
SREPN)
■
SRPPN is no longer in control.
