(ASCEND) Ascend Disconnect Performance

[Mitchell Arnone <mitchell.arnone@occ.treas.gov>]

We have been running two MAX TNTs for over a year and recently purchased 
Navis Access.  With Navis, and other "Log Watching" tools we have been able 
to understand more about the disconnect codes and progress codes.   In our 
attempt to become more proactive to network/dial-in problems we have 
identified some Disconnect/Progress code combinations that could indicate a 
systemic problem.  For instance, a 185 Disconnect with a progress of 31 
basically states that the two modems were unable to shake hands (no modem 
tone) so the TNT disconnected.  A 10 disconnect with a progress of 31 
indicates the same problem differing only in that it is the client which 
hangs up first.  On average, about 10% of our total analog disconnects are 
either a 185/31 or 10/31, although there have been times when this 
percentage has been as high as 30%  with users hollering.  Ascend has 
acknowledged that problems like this could possibly be addressed in a 
recent release of TNT firmware but this is not meant to imply that all such 
codes will disappear after the upgrade.  Also, there are other disconnect 
causes that have given us concern as well.

We are seeking to compare notes with other TNT users to see what kind of 
disconnects they are receiving and at what percentages.

Thanks in advance
