I have a Teles S0/16.3 card. My ISDN setup works OK mostly, except
that I can't make the connection time out, forcing me to disconnect
manually (using ifconfig isppp0 down).
I used these settings in isdnd.rc
idletime-incoming = 30
idletime-outgoing = 30
but, even more than two minutes after I cease communicating, the
connection stays up. Here is some debug output from isdnd (with
timestamps added) that may help to explain this:

(sorry, you need a wide window to really see what is happening)
Apparently, there is some sort of incoming traffic which hinders the
idle timer from ever reaching its timeout value.
What can this traffic be? How can I find out something more about it?
And is there a suitable workaround?
Maybe it is related to the next problem?
You see, the other problem is this.
While I am *not* online, I get messages like these in the log.

Is there perhaps noise on my S-bus, that the card is misinterpreting
as traffic? Or is there always some traffic on the S-bus, even when
nothing interesting is going on?
Again, how can I find out more about what is happening?
