as5300 - modem fails to handshake
AS5300
IOS 12.3(15)
modem version 2.9.5.0

Only used for incoming dial up

We have 3 ISDN/PRI incoming configured in nfas group. When the first T
reaches 23 lines in use and the calls roll over to the next T, the call
is assigned to a modem, but the modem does NOT initiate handshake sequence.

I know a debug on a bad call would help, unfortunately the create that
sequence of events is problematic. If the opportunity arises I will
post that info as well.

If anyone has any ideas, please let me know.

Re: as5300 - modem fails to handshake [ In reply to ]
A very typical cause for a symptom like this, when doing
NFAS, is "crossed spans". E.g. your T1 1 goes to
T1 1 on the switch, but your T1 2 goes to the switch's
T1 3 and your T1 3 goes to their T1 2.

If you unplug your T1 2 while you have your switch guy
on the phone, which T1 does *he* see go down?
