Software Increment Release Notes
================================
Increment ID:   I37A1730
Release:        AN1730
Date created:   5-10-2002
Increment Type: OPC

Title: OPC: Alarm Monitor and INM/Preside changes.
----------------------------------------------------------------------
Following is a list of issues addressed in this Increment. See below
for more details.

1. Alarm Monitor does not always store circuit pack entities.
2. Loss of comms not reported to INM/Preside for VM48 and VM24.

----------------------------------------------------------------------

1. Alarm Monitor does not always store circuit pack entities.
* Description: For AN17, the alarm monitor would not always store the
card type associated with different alarms in the historical data,
making alarm investigations difficult. The Alarm Monitoring real-time
tool always reflects the proper card type.
* Impact: Historical alarm analysis require additional effort to
determine the card associated with an alarm. This is only an impact
during alarm database research on an outage investigation, or other
historical alarm analysis.
* Pre-Increment work-around: None.

2. Loss of comms not reported to INM/Preside for VM48 and VM24.
* Description: When a Loss of Comms was reported for the AccessNode
Express VM48 or VM24 deployment, the alarm was not reported properly
to the Nortel Networks Integrated Network Manager (INM, renamed
Preside).
* Impact: This potentially service-affecting alarm would not appear
on the Network Manager, leaving a central monitoring position blind
to this alarm. Note, other alarms indicating a trouble at the network
element would be reported.
* Pre-Increment work-around: None.
