Hi, I have an hour window Thursday and Friday morning to test an E1 CME router setup with 8 channels, having never configured an E1 before I'm trying to cover all bases and am looking for some advice and clarification based on the config below.

I'm sure the customer has 8 channels, like BRI I presume this will allow 16 concurrent calls? Can anyone see any issues with the config? Also are there any recommended configuration options I should add?? Any help would be greatly appreciated.



network-clock-select 1 E1 0/3/0

isdn switch-type primary-net5

controller E1 0/3/0

pri-group timeslots 1-8,16

interface Serial0/3/0:15

no ip address

encapsulation hdlc

isdn switch-type primary-net5

isdn incoming-voice voice

isdn sending-complete

no cdp enable

Hi, seems it's all good, your pri will do as many calls as channels (8).

pri-group timeslots 1-18.

This to account the D channel.

you'll also need

network-clock-participate wic 0 - this will use the network clock for timing.

As mentioned by previous poster your configuration will only allow for 8 concurrent calls (1 per channel).

Don't forget to configure your voice-port cptone and also your dial-peers.

Thanks Guys, I now feel confident I can get what I need done with the limited testing time allocated.
