we're trying to setup an E1 interface on our cisco 2811 router, the IOS version is Cisco IOS Software, 2800 Software (C2800NM-IPBASE-M), Version 12.4(3f), RELEASE SOFTWARE (fc3)
I've tried running yourname(config)#controller e1 0/0 and get this result ^ % Invalid input detected at '^' marker.
or yourname(config)#card type e1 0 1 ^ % Invalid input detected at '^' marker.
yourname(config)#
do we have the wrong IOS version? or am i entering the wrong commands
