Software Increment Release Notes
================================
Increment ID:   I39A1800
Release:        AN1800
Date created:   4-20-2004
Increment Type: APU
Title: TXC CLEI, MLC circuits, Over-current, LCLOADCI, Call Reject
----------------------------------------------------------------------
Following is a list of issues addressed in this Increment. See below
for more details.
1. Invalid TXC CLEI code.
2. UE9000 MLC circuit failures after TDM SWACT.
3. Line cards stuck in over-current protection state.
4. LCLOADCI command increment fixes.
5. MVI incoming call rejections.
----------------------------------------------------------------------
1. Invalid TXC CLEI code.
* Description: Description: The TXC CLEI codes appear in the 
inventory screens with multiple questions marks (i.e. SAIU?????).
* Pre-Increment Impact and work-around: The CLEI code is affected
whenever a TXC pack is reinserted or deleted and re-added. This 
problem does not affect service. Avoid reseating or deleting and 
re-adding TXC packs before applying this patch.
* Note: Please refer to the special instructions below.
----------------------------------------------------------------------
2. UE9000 MLC circuit failures after TDM SWACT.
* Description: If a UE9000 TDM has an autonomous switch-of-activity 
(SWACT) during an APU intensive situation, like during an optical 
switch of activity, several MLC circuits may be failed.
* Pre-Increment Impact and work-around: Multiple circuits on each TDM
shelf that has an autonomous SWACT may experience the problem. 
Avoid optical switches of activity until this patch is applied.
----------------------------------------------------------------------
3. Line cards stuck in over-current protection state.
* Description: Lightning voltage or other abnormal voltage surges 
can cause certain types of circuits to go into an over-current state. 
These circuits may not automatically recover from this state and need 
to be manually recovered. These pack types include all vintages of
the NT4K65 CDS Epsilon, NTN502 ANX Epsilon II, UE9000 NTNP40 POTS-24,
and NTNP42 UVG-24 line cards.
* Pre-Increment Impact and work-around: The circuit is unavailable
for call processing until it is manually reset at the craft level
of the AccessNode Human Machine Interface (HMI).
----------------------------------------------------------------------
4. LCLOADCI command increment fixes.
* Description: The LCLOADCI command increment tool set default 
diagnostic and load ID commands may not work for all lines when 
setting multiple MLC circuits.
* Pre-Increment Impact and work-around: Using the LCLOADCI
commands to change the diagnostic or load IDs for many MLC 
circuits at once may yield unreliable results. The command 
works when setting IDs on a single line at a time.
----------------------------------------------------------------------
5. MVI incoming call rejections
* Description: If a MVI subscriber goes on-hook between 1.1 and 
1.3 seconds before an incoming call is received, there is a chance 
that the incoming call would be rejected.
* Pre-Increment Impact and work-around: When this occurs, the MVI 
subscriber is not aware of the incoming call rejection and the 
originator gets call failure treatment. Subsequent call attempts 
to the MVI subscriber are successful.
----------------------------------------------------------------------
Increments Needed:
----------------------------------------------------------------------
Increment I01A1800 through I38A11800 needs to be successfully applied 
prior to application of this increment.
----------------------------------------------------------------------
Loads Affected:
----------------------------------------------------------------------
APU: ACCL18BC 
APU: ATBL18BC 
----------------------------------------------------------------------
Special Instructions:
----------------------------------------------------------------------
This patch should be applied and all affected TXC packs experiencing
a CLEI problem need to be placed out-of-service, deleted, re-added, 
and then placed back into service to clear the CLEI issue.
