       ds0-group 0 timeslots 1-15,17-31 type r2-digital r2-compelled ani  -> no accept this command because the voice-port no exist

Yesenia,

Is that the exact error the router is giving you?

Can you attach the following show commands?

show run

show ver

show inv

Also what was the exact commands you followed to make the change?

~ Luis Ramirez,

Hi,

Here is a basic template to configure an E1:

network-clock-participate wic 0

network-clock-select 1 E1 0/0/0

isdn switch-type primary-net

controller E1 0/0/0

pri-group timeslots 1-31

interface Serial0/0/0:15

no ip address

encapsulation hdlc

isdn switch-type primary-net5

isdn overlap-receiving

isdn incoming-voice voice

no cdp enable

voice-port 0/0/0:15

cptone (your country)

Or is this what your are trying to achieve?

controller E1 0

clock source line primary

ds0-group 0 timeslots 1-15,17-31 type r2-digital r2-compelled

cas-custom 0

voice-port 0:0
