I have a Cisco 3745 as follows:
2 FastEthernet interfaces
31 Serial interfaces
1 ISDN Basic Rate interface
60 terminal lines
2 Channelized E1/PRI ports
I have it configured for dial in with radius authentication for PSTN users. This works fine and all ASYNC users connect fine. However, when an ISDN user connects they authenticate fine, but the connection then drops. I have debugged ppp authentication and it seems fine. I can't find any errors.
I am sure I am missing some config somewhere. Any help you guys can give is appreciated :)
