Manual Exit; Ltc Maintenance To Prevent Esa Mode - Nortel DMS-100 Series Maintenance Manual

3. Load the ESA static data into the RCP card by typing
>LOADPM PM CC ESADATA
and pressing the Enter key.
Example of a MAP display
WARNING: PM cannot enter ESA while loading ESADATA to both
units simultaneously. Do you wish to continue loading both
units? Please confirm ("Yes", "Y", "No", or "N"):
4. Respond to the confirmation request. If N is entered, only one unit is
loaded with ESADATA.
If this process fails, the Star Hub becomes ISTb.

Manual exit

A manual exit from ESA is necessary if operating company personnel have
busied the Star Hub before the recovery of communication or during the
system exit time-out period. Both units must be busied, otherwise the CC
attempts a system exit on the unit which is in a SysB state as soon as
communication is restored.
Use the RTS command to perform a manual exit from the ESA mode at the
STAR MAP level. A manual exit is required when the
• two Star Hub units are in a ManB state
• time-out value for the RLCM_XPMESAEXIT office parameter is set to
zero
Note: To manually override a time-out value other than zero, manually
busy the Star Hub units at the STAR MAP level. This process starts a
manual exit. Use the FORCE option with the BSY command.
The manual exit sequence is described in the "ESA manual exit" section in this
chapter.

LTC maintenance to prevent ESA mode

When the two LTC units are ManB, communication between the Star Hub and
DMS-100 CC is interrupted. When communication between the Star Hub and
the DMS-100 CC is interrupted, the Star Hub enters ESA mode. The Star Hub
enters this mode after the time-out period in the
RLCM_ESAENTRY_BADCSIDE office parameter expires. The following
warning message displays when an attempt is made to manually busy an LTC.
This action will take this PM and its subtending nodes out of
service.
