asterisk users - Aug 2007 - low-level dump for PRI dchan debugging

I've been going back and forth with my telco for several days, trying
different configurations to get a new PRI to come up.  The bchannels
are all up and the T1 is not in alarm status.  The dchannel refuses to
come up however.  We've tried ni2, qsig, and now dms100 for the
switchtype.  The telco tech I've been working with says that he's been
sending "reset all channels" signals to my system, to which he's
getting an "establish remote" response from my asterisk box.  I've
been running a packet dump (wanpipemon -i w1g1 -c trd) of my d-channel
this whole time and have yet to see a single incoming packet.  I
believe I *should* be seeing an incoming packet when he sends the
reset, correct?  Is there any way to do a completely raw dump of the
d-channel?

Here are my specs:
linux-2.6.16
libpri-1.3.5
zaptel-1.2.19
asterisk-1.2.21.1

The PRI interface is a Sangoma A102...it's running the latest firmware
and I'm running wanpipe-2.3.4-12 for the sangoma drivers.

Any ideas?

Call Sangoma and give them root if you can.  They will fix it quickly or 
at least give you ammunition that it is the telco's issue.

Thanks,
Steve

wanpipemon is the way to do it as far as I know.

For starters, what do your zaptel/zapata configs look like?

I would first verify that your D-channel is set properly, you can view
that in the console as follows:
asterisk> pri show span 1/0
Primary D-channel: 24
Status: Provisioned, Up, Active
Switchtype: National ISDN

Have you completely ignored the telco suggestion and attempted pri_cpe?
Sounds like a miscommunication in settings to me.

lpdlnx04*CLI> pri show span 1
Primary D-channel: 24
Status: Provisioned, Down, Active
Switchtype: Nortel DMS100
Type: Network

I know it's odd, but the telco instructed me to set my equipment as
the network end...hence pri_net:

/etc/zaptel.conf
loadzone=us
defaultzone=us

#Sangoma A102 port 1 [slot:10 bus:2 span: 1]
span=1,1,0,esf,b8zs
bchan=1-8
dchan=24


/etc/asterisk/zapata.conf
[trunkgroups]

[channels]
context=default
usecallerid=yes
hidecallerid=no
callwaiting=yes
usecallingpres=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
canpark=yes
cancallforward=yes
callreturn=yes
echocancel=yes
echocancelwhenbridged=yes
relaxdtmf=yes
rxgain=0.0
txgain=0.0
group=1
callgroup=1
pickupgroup=1

immediate=no

;;Sangoma A102 port 1 [slot:10 bus:2 span: 1]
switchtype=dms100
context=from-pstn
group=1
signalling=pri_net
channel => 1-8

There you go.

As an aside, turns out that it's a national holiday in CA, so the
Sangoma support guys are on vacation for the day.

Thanks to everyone who offered suggestions on how to troubleshoot this
issue.  After working with the telco for over a week on this, I
finally got them to admit today that they have a configuration
problem.  I had been telling this since day 1, but they didn't listen
to me.  Their change in perspective came when they had a tech come
on-site with a PRI emulator device.  He connected that directly to my
asterisk server and was able to make calls with no issues whatsoever.
Fortunately after this final test, they admitted that the problem must
be on their end.  Hopefully they'll get it sorted today.

As an aside, I had a quick question regarding smartjacks.  Is there a
jumper or something on the smartjack itself to change from an
old-style E&M T1 to a PRI?  I'd think that change would happen in the
telco's switch, but I just thought it might be a possibility.  In my
case, as I stated in my original email, the bchannels come up fine,
but not the dchannel.  This makes me think it could be something
simple...
