[cisco-nas] X.75 and modem dial-in, autocommand to TCP

Hi Aaron,

this "X.75 and modem dial-in" thing is slowly proceeding...

... and this works nicely for X.75 calls (adding the initially-missing
"transport input lapb-ta").  Indeed, it works *very* well :-))


I'm stuck with modem calls, though.  Both the 3640 + NM-30DM and the
AS5300 that we bought in the mean time show the same error message upon
incoming modem calls ("debug isdn event" is active):

ISDN Se0:15 EVENT: process_rxstate: ces/callid 1/0x1C calltype 2 CALL_INCOMING
ISDN Se0:15 EVENT: UserIdle: callid 0x1C received ACCEPT_CALL (0x13)
ISDN Se0:15 **ERROR**: accept_incoming_csm_call: modem problem Requested circuit/channel not available(0x2C): b channel 0, call id 0x1C
ISDN Se0:15 EVENT: process_rxstate: ces/callid 1/0x1C calltype 2 CALL_CLEARED


- I couldn't find anything in google that gave me a useful hint on why
it doesn't want to accept the modem call, or how to further debug this :-(

I did some experiments with "group-async" interfaces, but that didn't
really change anything (and also seems to be the way to run IP over modems,
which I don't need).

... this is configured, with "transport input all", but doesn't seem to
be enough.
