[Asterisk-Users] Problem getting D channel up on Sangoma A102

Hi all,

  I am installing an Asterisk box equipped with the Sangoma A102 card. The telco
just tested the PRI interface and it is ll ok. I
now connect my Asterisk box and I can't get the D-Channel up. If I enable
intense pri debug I see messages like the following:

A couple of items to check....

How sure are you the d-channel is on channel 24?

Check with the telco when you are ready to test as they will typically
disable the pri link to reduce the number of alarms they receive. They
are running under the assumption that you've not installed your stuff
yet and won't activate the d-channel (etc) until they know you are truly
ready to test/use the circuit.

Ensure you've connected your Sangoma card to the telco jack using a
T1/E1 cable.

Last, it is not uncommon (at least in the US) to find newly installed
circuits that some telco technician left in loopback. In very general
terms, one of their last installation steps is for them to loop back the 
circuit (at your location) and then send/receive data through the circuit
from their central office to measure bit error rates, etc. If they forget 
to dump that loopback, you are essentially sending calls to a unterminated 
T1/E1 circuit.

[Asterisk-Users] Problem getting D channel up on Sangoma A102

Try to recompile/reinstall (make clean; make install) zaptel after the
wanpipe installation to have the new 'patched' zaptel modules installed
on
your system.

Also, make sure the Asterisk application is running.  The span will be clean
without it, but the application itself generates the d-channel messages.

zaptel.conf:
span=1,1,2,esf,b8zs
bchan=1-23
dchan=24
loadzone = us
defaultzone=us

zapata.conf

signalling=pri_cpe
faxdetect=incoming
usecallerid=yes
echocancel=yes
echocancelwhenbridged=no
echotraining=800
group=1

Any hints appreciated
