Hi,

We're trying to diagnose dropped ARAP connections on our 2511 and UDS v.34R 
system.

Users can connect, but they will be dropped after a period of time. The time 
varies. Sometimes the connection will last for several hours, sometimes for 
minutes.

The "sh li" doesn't show big problems with line noise, however the TACACS log 
shows noise on some of the lines at the initial connection attempt.

Here's how we've got the lines configured:

 line 1 16
 exec-timeout 0 0
 login tacacs
 modem ri-is-cd
 arap enable
 arap zonelist 610
 transport input all
 escape-character BREAK
 stopbits 1
 rxspeed 38400
 txspeed 38400
 flowcontrol hardware
 dispatch-timeout 1
 dispatch-character 126

Could the dispatch-character be biting us? (I don't think so, but we're 
starting to grab at straws.)

Also, here's our modem configuration:
