Has anyone out there had any luck getting a B410p BRI card working in NT mode?
Here’s what we’re trying to do:
We’ve got an OpenSuse 10.2 box running Asterisk 1.4.5 with a B410p card with two of the ports in NT mode, and the other two in TE mode. We’re trying to connect one of the NT ports to a BRI interface on our “Commander Connect” PABX. The Commander is a rebadged Lake Communications box which is sold by BT as “Versatility”.
No matter what I’ve tried, I cannot get a L1 link between the Commander and the B410p to come up. The driver appears to load ok, and asterisk seems happy with the config. I’ve tested the TE ports into one of the ISDN NT1s being used by the Commander, and it works correctly (including sending and receiving calls).
I can connect one of the TE ports to one of the NT ports on the same card, and the link comes up.
I don’t have an ISDN handset to test with, but I have tried connecting the ISDN port on a Cisco router and I get L1 link.
I’ve tried different kernel versions, different versions of mISDN (1_1_3, 1_1_4 and the latest via GIT) and different versions of Asterisk (1.2, 1.4). I’ve tried kernel versions 188.8.131.52 and 184.108.40.206 on the current server as well as a TrixBox 2.2 installation on a different machine, and none of them work.
At this stage, I’m thinking that there must be some line level signaling that the Commander is expecting that the B410p doesn’t provide - but I cannot find anything else to try changing.
Has anyone out there had any luck with this sort of thing?
