Hello,

I have a new 2811 with an PRI ISDN card installed (NM-1CE1B=) and can not seem to enable and configure it. I have tried the usual commands:

card type e1...

controller e1...

...but neither are accepted. It wont even accept configuring ISDN switch-type global commands. It doesn't appear to accept any ISDN commands at all. I have tried 2 differenet IOS levels which both state they accept ISDN:

Cisco 2811

c2800nm-advipservicesk9-mz.124-3g.bin

c2800nm-adventerprisek9-mz.124-9.T.bin

Can anyone advise a level of IOS to use pleased?

rgds
