Re: how to check loop break in PRI

This link may help. But it indicate the loopback test for the router and not the line. I believe you have to ask the PTT to do it loopback test t their side.

Hi Parvinder,

To check the loop from the service provider on router you need to run debug for isdn.Use command debug isdn q921.Refer to following link for troubleshooting tips on T1 PRI.
