I am having some difficulties getting my Asterisk box to find the d-channel from a TELUS PRI and am waiting to hear back from one of their techs. In the meantime I thought I would check with the brilliant people of the mailing list.
As I understand it is a T1 connection, not an E1 and I am using a Digium TE121 with hardware echo cancellation. I have green lights on the back of the card and the PRI connection, which go red when I do a dahdi restart command and come back to green once it is finished.
I know from our other system that the frame and coding are ESF and B8ZS so it must be something in the signaling of the channels. My chan_dadhdi is below, the commented out lines are ones I have tried. I’ve also tried moving the dchannel around, 12 through 24. Does anyone see anything blatantly wrong?
trunkgroup => 1,24
spanmap => 1,1,0,esf,b8zs
;signalling => em
;signalling => pri_net
signalling => pri_cpe
;group = 1
bchannel => 1-12
dchannel => 24
