I've been banging my head against the wall for a while (almost 18
hours today alone) with this one... I migrated our incomming T1's from
the Option 11 to our Asterisk box this morning. We have 1 local T1 and
2 long distance T1's. The local T1 went over with out a hitch. The
problem is with my 2 long distance T1's. The switch on the other end
is a DMS250 I'm told so I set Asterisk to DMS100 and got the timing,
framing, etc all set. Well, the D channels came up so thats good. I
started getting dropped calls every once in a while. I did a debug on
the spans and saw the following:
Sounds similar to what I am doing. Migrating from a Nortel Option 61 to
Asterisk. I have everything set, and am just waiting for an appropriate
window to move the 4 T-1s (2 trunk groups). All PRIs are national
though, not DMS100.
I tried configuring a trunkgroup and set the primary dch to 24 and the
bdch to 72 and then then spanmap'ed span 2 and 3 into group 1 (e.g.
2,1,0 and 3,1,1) but I don't see anything when I do a "dahdi show
channels" or a "pri show spans" or a "pri show channels", not even the
channels not in the group. If I delete the trunkgroup, all three
commands return all the channels.
I'm just curious if I'm going down the right path with trunkgroups for
this or if there is something else to take care of the DS1 Identifier
issue.
Here are the relevant portions of my configs, I based them on a working
model for PRIs connecting the Asterisk to the Option 61 as TIE trunks.
This config has two dual port cards, with span 1 and 3 being a group and
2 and 4 being a different group. I hope this helps. (Or perhaps
identifies something I have wrong that may not have been found yet ;-)
