Dial-In to Access Server : Line hangs up after approx. 160 sec.

schimekh

Level 1

I am using a 3660 Access Router.

ISDN and analog modems.

I configured group-asynch interfaces - Dial In to these interfaces is successful - the asynch interface comes up but disconnects automatically after approx. 160 sec.

(additionally I am using TACACS authentification on a Cisco ACS)

Unfortunately I noticed this bevaviour after changing over to this ACS -

we were using Windows NT Active Dir. before .

I see the following errors:

TTY78: Async Int reset: Dropping DTR
