At last European european cisco meeting in Nice, cisco people have asked if
there is interest in such an interface. User responses were positive,
especially for using ISDN as backup. But only 3-4 guys were interested to use
cisco to interconnect LANs using only ISDN.

I think that cisco will not provide an interface for the basic ISDN access
(2x64 kbps + D), but will perhaps provide an interface for the primary ISDN
access (30x64 kbps + D). With such an interface, connexion to multiple sites
can be done simultaneously, or even you can dynamically adjust the number of
channels with the trafic volume.

We have just started to test LANs connexion with ISDN using cisco routers here
at our university. Instead of using an interface in the cisco box, we use an
external ISDN adapter (ISDN <> V35). It seem's to work fine till yet. For the
moment we start and stop the connexion manually, but we hope to find some way
to provide automatic dialing in a near future.

Happy ISDNing.
