I have no experience with ISDN configuration. Can anyone please help me configure this one or maybe point to a url closely related to what i have. I have 3640 on both ends with NM-HDV-2T. Our Telco is said to be using CSS with basic-5ess for its switch-type.
For both routers, i have also Controller-T1 for voice traffic. Below is the diagram for this one:
[Telco]---ISDN---[Router1]--PPP leased line--[Router2]---[PBX]
Thanks for the quick response.
