Software Increment Release Notes
================================
Increment ID:   I42A1800
Release:        AN18
Date created:   07-17-2005
Increment Type: APU
Title: Recover from Line Card loading issues after applying an ESUP.
----------------------------------------------------------------------
This Increment addresses the following issues. See below for more
details.
1. Recover from Line Card loading issues after applying an ESUP.
----------------------------------------------------------------------
1. Recover from Line Card loading issues after applying an ESUP.
* Description: When applying an Emergency Supplemental UPdate (ESUP) to
the AccessNode, the NT4K67 and NTNP41 cards could fail to load. Common
ESUP loads applied to the AccessNode are the "SL" load context for 
Extension in Use (EIU) Loop Start Residential (LSR) issues, and the "LR"
load for Electronic Business Sets (EBS) that are ringing too loud. A
LC308 line card log will be generated by the AccessNode indicating that
there has been a "Communication Error" when attempting to load the new
linecard load. The line will be left in a total fail condition, and 
will not provide service until the linecard context is set back to the
original context.
* Pre-Increment Impact and work-around: Incremental line card ESUP loads
may fail to load even though they are properly placed and provisioned
based on ESUP application notes delivered with the ESUP loads. GSS
intervention would be needed to get the loads to apply.

Increments Needed:
----------------------------------------------------------------------
Increment I01A1800 through I41A1800 need to be successfully applied 
prior to the application of this increment.
----------------------------------------------------------------------
Loads Affected:
----------------------------------------------------------------------
After successful application of this increment, the APU loads will be:
ACCL18BC
ATBL18BC
----------------------------------------------------------------------
Special Instructions:
----------------------------------------------------------------------
If a special ESUP load had been applied to the AccessNode prior to the
installation of this increment, a line could still fail to load and
generate an LC308 log indicating "Communication Error". In this case, 
the telco technician must re-issue the SETDFTID command in order for 
the ESUP load to be successfully found and delivered to the circuit.
Once this SETDFTID command has be re-issued, a LC501 log will be 
generated for each line indicating that the "Bad Line Card Restored".
