Back-to-Back ISDN Communication

[vnegre]

Hi!

Is it possible to connect two routers, i.e. 2651 & 2621 each with ISDN BRI interface, back-to-back via 1-Port ISDN with NT-1 WAN Interface Card. If possible... how to connect it?

Thanks...

Hi,

For BRI interfaces,connecting each other there must be a device for switching. This is called an ISDN switch. But if you would use ISDN PRI , you could connect 2 of them directly each other & configure one to simulate network side.

So as far as I know , Cisco routers cann't simulate an ISDN switch.

I hope this helps

No you need an ISDN Switch. Teltone makes a nice ISDN simulator you can pickup on Ebay for around $1600.00.
