Thanks Alex, but I already have an idle-timer value of over 2 million
seconds as well as the load-threshold set to 1.
As Tony pointed out earlier, it appears from the debugs to be a problem
during the LCP negotiation phase, prior to even attempting to authenticate
with CHAP.
Here is some of the debug output, showing what I mean. This is the calling
1700 router output:
05:31:180388626431: %LINK-3-UPDOWN: Interface BRI0:2, changed state to up
05:31:178241142757: BR0:2 PPP: Treating connection as a callout

05:31:43: BR0:2 LCP: TIMEout: State ACKsent
This same events occurs again, and again until 20secs are up and the line
drops. It does not even get to the authentication phase. I think I need to
try and figure out why it is getting a "TIMEout: State ACKsent".
Thanks for the suggestions, keep them coming!!!
Thanks again,
Sam.
