howto simulate a pri on 2600

I have a 2651XM with a 1DSU-T1 and a WIC-2MFT-t1 and need to use either of these WIC's to simulate a PRI. I assume this is possible, but have not been able to find any info on it. The phone guys have asked if there was a way to get them a PRI to test remote office PBX's before they ship.

Re: howto simulate a pri on 2600

You can simulate a voice PRI on a 2600 as long as you have DSP resources. If you want to make voice calls through it, the easiest way is to use something like a NM-2V card with VIC-2FXS , the AIM-VOICE-30 DSP card and a VWIC-1MFT-T1 card.

The following config would work -

isdn switch-type primary-ni

network-clock-participate wic 0

network-clock-select 1 t1 0/0

controller t1 0/0

pri-group timeslots 1-24

interface serial 0/0:23

isdn switch-type primary-ni

isdn incoming-voice voice

isdn protocol-emulate network

dial-peer voice 1 pots

incoming called-number .

port 0/0:23


dial-peer voice 2 pots

description - calls to PRI

destination-pattern 1...

port 0/0:23

prefix 1

dial-peer voice 3 pots

description - calls to FXS ports

destination-pattern 2...

port 1/0/0

we use these configs all the time in the lab as PBX simulators . You need a T1 cross over cable to bring up the interface -

1 ---- 4

2 ---- 5

4 ---- 1

5 ---- 2
