Software Increment Release Notes
================================
Increment ID:   I34A1730
Release:        AN1730
Date created:   January 17th, 2002
Increment Type: APU
Title: Spurious APC detection and Upgrade enhancements

----------------------------------------------------------------------
Following is a list of changes included in this Increment. See below
for more details.

1. Prevent spurious APC detection on simplex processor systems.
2. Upgrade enhancements. 

----------------------------------------------------------------------
1. Prevent spurious APC detection on simplex processor systems. 
* Description: An intermittent problem could cause the active APC to
create the instance of a false mate processor on a simplex system due
to a spurious APC detection.
* Impact: Raises loss of data synchronization and mate communication
alarms as well as processor unequipped alarm.  If the condition
exists, it could also cause problems during an Upgrade. 
* Pre-Increment work-around: The alarms can be turned off through the
Proc Equipment Alarm Provisioning menu in the AccessNode NE UI. 
This will prevent the alarms from being reported to the user.

2. Upgrade enhancements. 
* Description: Introduce feature enhancements to allow for AN17.30 to
AN19.05 upgrades. 
* Impact: Without this increment the overall time to complete an
AN17.30 to AN19.05 Upgrade will be increased by approximately
30 minutes. 
* Pre-Increment work-around: There is no work around available.
