Hi Guys,
I'm currently on a customer site to migrating from classic telephony to ToIP.
I have a 2901 router (MGCP), with two vwic3-amft-t1/e1 card.
The provider give me two E1, one with 30 channels and the other with15 channels.
I'm testing with the 30 channels E1 on my E10/0/0 port.
When I unplug the E1 cable from the old PABX, and plug into my 2901, nothing happens : controller E1 stay down and amber alarm led is fix.
If i unplug the cable from the E1 port of my 2901 the amber alarm light stay fix too.
The E1 works on the old PABX ...
You can fin a show controller E1 just there :
