Software Increment Release Notes
================================
Increment ID:   I01A1960
Release:        AN1960
Date created:   10-10-2003
Increment Type: APU
Title: 2688 Voltage Message Waiting, UE9K D-link recovery and ESA
----------------------------------------------------------------------
Following is a list of issues addressed in this Increment. See below
for more details.
1. 2688 Voltage Message Waiting Provisioning on CDS.
2. UE9K loss of active D-link recovery enhancements.
3. ESA recovery actions.
----------------------------------------------------------------------
1. 2688 Voltage Message Waiting Provisioning on CDS.
* Description: New in AN19.60 is the introduction of the CSC 2688
feature, allowing for identical LENs to exist on the Network Element to
different CSC hosts. When this feature is activated, an issue exists 
where the card code returned on a MWT provisioning action from
the second CSC host would return the hardware assigned in the slot for
the first CSC host. This could cause the provisioning of MWT to fail,
stating that the card in the slot does not support the feature. 
Conversely, if the LEN on the first CSC host supports the message
waiting feature, then the second DMS CSC host could allow the provisioning 
to go through on an AccessNode line that does not support the voltage 
message waiting feature.
* Pre-Increment Impact and work-around: This issue only exists on the
CDS shelf.  The 2688 CSC feature operates correctly on the line, and 
only the hardware query returns an error for the CDS. Prior to 
implementing this increment, it is possible to work-around the issue 
by momentarily swapping the line card assigned to the first host, which
will allow the provisioning by the second CSC host to go through.
----------------------------------------------------------------------
2. UE9K loss of active D-link recovery enhancements.
* Description: When D-link connectivity is lost to the active UE9K TDM,
the active TDM will go missing and the inactive TDM will fail. 
* Pre-Increment Impact and work-around: In order to recover the UE9K 
prior to this increment, the active TDM would need to be removed and 
re-inserted. Once this increment is applied, the UE9K will perform a 
cold swact in most cases to recover customer traffic. Our UE9K 
customers should take care to ensure that all D-link connections are 
properly fastened onto the TDM faceplate connector in order to prevent
this issue from occurring.
----------------------------------------------------------------------
3. ESA recovery actions.
* Description: Once conditions were met for an exit from an Emergency
Stand-alone event, the system could fail to exit from the stand-alone
condition.
* Pre-Increment Impact and work-around: Should an event occur that 
takes the node into ESA, the exit criteria may not return the node
to full service. A system audit would return the node to standard
operations after fifteen minutes.
