Software Increment Release Notes
================================

Increment ID:   I06A1730 
Date created:   05/05/00
CSR number:     UT02910A, 50134745, 50317701, CM90368, UT00820

Title: ANX LC total fail, ANX x-con tool, & babbling modem interrupts.

Detailed Description of Increment:  
----------------------------------
This patch bundles fixes for three issues. The first is a 
problem where all LCs at all VMs go into a Total Fail state. 
The error is caused by an SMS message queue corruption.  The 
corruption blocks guaranteed messages between the ABM and VMs.
The second issue is a problem with babbling modem interrupts.
The issue is a reduction or even degradation of real time by 
a modem that is babbling with erroneous data.  The third issue
is a problem using using the PCGUI cross connect button where a
deny response error message is received.

  3) Select on e of these options:
     1) Apply to ALL NEs (to set the increment fully into the system)
     2) Trial on one NE (to test the increment to ensure that it causes
        no problems)

     If you select option 2, a list of NEs in the span of control appears.

Test Instructions:
------------------
Two of the fixes cannot be readily verified other than through
reproducing the problem. These are the SMS queue corruption
and babbling modem issues.  Since these error conditions are a 
degradation of service, it is suggested monitoring for recurrences
of the issue and checking system integrity after patch application
is the best method.  The third issue is easily checked in PCGUI.
