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

3-32 ESA maintenance overview

ESA manual exit

Operating company personnel can use the RTS command to perform a
manual exit from the ESA mode at the LCM MAP level. A manual exit is
required under the following conditions:
The manual exit sequence is described in the "ESA manual exit" section of
this document.

LTC maintenance to prevent ESA mode

When the two LTC (C-side peripheral) units are ManB, communication
between the RLCM and DMS CC is interrupted. When communication
between the RLCM and the DMS CC is interrupted, the RLCM enters ESA
mode. The RLCM enters this mode after the time-out period in the
RLCM_ESAENTRY_BADCSIDE office parameter expires. The warning
message that occurs during attempts to manually busy an LTC is as follows:
This action will take this PM and its subtending nodes out of
service.
Busy the RLCM or ESA CC before you place the LTC in a ManB state.
This action does not allow the RLCM to go to ESA mode.
297–8351–550 Standard 04.01 August 1999
The two LCM units of the RLCM are in a ManB state.
The time-out value for the RLCM_XPMESAEXIT office parameter is
set to zero.
Note: To manually override a time-out value other than zero,
manual-busy the LCM units of the RLCM at the LCM MAP level. This
process starts a manual exit. Use the FORCE option with the BSY
command.
