Software Increment Release Notes
================================
Increment ID:   I02A1960
Release:        AN1960
Date created:   10-30-2003
Increment Type: TDM
Title: UE9K Store Utilization Change, D-link Robustness.
----------------------------------------------------------------------
Following is a list of issues addressed in this Increment. See below
for more details.
1. UE9K Store Utilization Change.
2. D-link recovery enhancement.
----------------------------------------------------------------------
1. UE9K Store Utilization Change.
* Description: Enhanced messaging to the UE9K in the AN19.60 release
caused inappropriate memory allocations to occur. This increment will
release memory after it has been used.
* Pre-Increment Impact and work-around: Before the application of this
increment, it would be possible for the UE9K to exhaust all available
memory. Should this occur, the active TDM would go into the UEQ 
(unequipped) status, even though it was plugged into the shelf and the
faceplate lights indicated normal, working status. The NE would raise 
a Critical Service-affecting alarm on the UE9K, and all traffic would
be lost. In order to fix a UE9K in this condition, the active TDM card
would need to be removed to force a switch of activity. The user could
execute regular warm restarts on a monthly basis on both the active 
and standby units in order to prevent this from occurring. This impacts 
the UE9K only, not the UE Remote (UER).
----------------------------------------------------------------------
2. D-link recovery enhancement.
* Description: When D-link connectivity is lost to the standby UE9K 
TDM, the D-link will properly alarm and the system will take action.
However, if the D-link were to fail a second time, the notification
of the failed D-link could be ignored and not reported by the system.
* Pre-Increment Impact and work-around: Before the application of this
increment, it would be possible for the standby TDM to have a non-
reported D-link failure. Should this TDM become the active TDM, the 
customer could experience loss of dialtone.
