[asterisk-users] debian/dahdi/zaphfc - Unable to receive TEI from network!
Hello,
The harddisk of my etch/bristuffed asterisk1.2 box finally died. I moved
the cheap (1397:2bd0) HFC-S card to a squeeze host (i686) and built
dahdi modules 2.3.0.1 using m-a. After zaptel->dahdi and asterisk
1.2->1.6 config adaptations, everything seems ok, except for the BRI
side, unable to bring layers 1/2 up.
Asterisk reports:
chan_dahdi.c:12393 dahdi_pri_error: 1 Unable to receive TEI from network!
deskpro*CLI> pri show spans
PRI span 1/0: Provisioned, Down, Active
Of course, trying to dial out using the channel results in:
app_dial.c: Unable to create channel of type 'DAHDI' (cause 34 -
Circuit/channel congestion)
I'm a little puzzled as to what's wrong, as I didn't change anything
on
the ISDN side compared to my very stable etch setup: same HFC-S card
working in TE-mode, same bri_cpe_ptmp signalling, same NT1, I even
reused the same cable. I tried the force_l1_up=1 kmod parameter, without
seeing any change. I tried using fcshdlc instead of hardhdlc with no
luck. I even swapped the NT1 with a new one, also without result. Any
pointers on how to debug this TEI assignment
problem are welcome.
I have an plain ISDN phone that's also connected to the NT1's S-bus
which works fine. I can swap the cables between the phone and HFC-S card
or disconnect the phone, it doesn't change anything.
OS-level and asterisk-level stuff looks as per my expectations (which
may be misguided...). The only strange thing is the warn_slowpath_common
warning when loading zaphfc module, but I'm not sure whether this is
relevant as people seem to have a working setup despite seeing this
warning. Can anyone confirm that this is not relevant?
I include some info on my setup below. I can also provide config files
for the previously running etch/asterisk1.2 setup, if requested.
Thanks for any help
