Hello all,<br><br>We have a 2611XM with a T1 interface that I'm using to interface with a PBX at a remote site (I think its a Nortel Meridian but i'm not familiar). We are interfacing with a PRI connection and a T1 crossover cable (gateway is sitting right next to the PBX in the closet). Whats odd about this though is the T1 controller is showing a "Reciever has loss of signal" alarm message, but everything is working.. D Channel is up and we can make calls back and forth. I was also expecting to see a line saying it was transmitting an alarm back to the PBX if it wasnt recieving any framing, but that isnt on there either:
<br>T1 1/0 is up.<br> Applique type is Channelized T1<br> Cablelength is long gain36 0db<br> Receiver has loss of signal.<br> alarm-trigger is not set<br> Version info Firmware: 20050620, FPGA: 16, spm_count = 281942
