That's interesting that a problem caused by the distance to the demarc
should be resolved by disabling PPP multilink......but i've seen stranger
things too.
Just a note on your statement regarding the dialer load-threshold statement:
The number you put at the end of this statement can be of any value between
1 and 255, and is not really a measure of bytes or bits. Its a value used
when comparing the traffic load on the first B channel when deciding when to
activate the second B channel. For example, a value of 200 would mean that
you want the second B channel to be activated when the load on the first one
reaches about 78% (200/255*100). Its needed on the dialing side. A peer that
only receives calls wouln't need the statement.
Hans,
Have you been able to run other debugs such as debug dialer or debug isdn
q931? These could possible give output that could be eye-opening. The call
here is disconnected after 120 seconds which is also the default value for
the dialer idle-timeout. But you menioned that you do have traffic going
across at that time. Can you post the relevant configs for both ends? If
there's nothing wrong with them, you could be running into a bug where the
idle timer is not reset despite interesting traffic. I don't have the ID
right now, but know there is one.
