Software Increment Release Notes
================================
Increment ID:   I06A1960
Release:        AN1960
Date created:   09-24-2004
Increment Type: UER
Title: UE9K MLC Service Enhancements 
----------------------------------------------------------------------
Following is a list of issues addressed in this Increment. See below
for more details.
1. MLC line circuit testing.
2. MLC failures due to ringing an off-hook line.
3. MLC circuit pack missing false alarm at the UER BIP
----------------------------------------------------------------------
1. MLC line circuit testing.
* Description: A line circuit's test bus may be left active causing
erroneous values when testing other line circuits on the same shelf.
* Pre-Increment Impact and work-around: Before the application of this
increment, it may be possible for a line circuit test bus to be left 
active on the MLC. The effect of this condition is that other line tests  
conducted on other circuits on the same shelf could return errored
results. Re-seating the MLC is the only known work-around. 
----------------------------------------------------------------------
2. MLC failures due to ringing an off-hook line.
* Description: When ringing is applied to a off-hook line card for a
short period of time, the entire MLC may fail and reset.
This occurrence should be relatively rare, as the terminating line 
must go off-hook in a window of a just few milliseconds.
* Pre-Increment Impact and work-around: Before the application of this
increment, the MLC would fail, reset and usually recover on its own. 
Follow-up testing of the MLC would not indicate any problems. 
No work-around is necessary, as the MLC would usually recover on 
its own. 
----------------------------------------------------------------------
3. MLC circuit pack missing false alarm at the UER BIP
* Description: For the UER, the local shelf raises alarms for all 
linecard slots should there be no line card circuit pack installed. 
The circuit pack missing alarm is reported to the ABM shelf, which 
compares what cards have service provisioned on them and raises only 
those Circuit pack missing alarms on the ABM that have service on them.
Prior to this increment, if the customer has the UER alarms wired to 
the BIP at the remote location (BipServer), the Major Circuit pack 
missing alarms are always present at the UER BIP. This increment will
suppress at the UER BIP the alarms raised for missing line card packs
that have no service provisioned.
* Pre-Increment Impact and work-around: None.
