[asterisk-users] Problem with wct4xxp - cannot make calls

Tue Jul 6 12:53:31 CDT 2010

  Hi,

I'm having problems with a TE420P card, in which I cannot make calls 
using spans 2 through 4.

After a couple of days of working correctly, spans 2, 3 and 4 start 
failing (can not make calls). The system is configured to work with SS7. 
After the ACM message goes out, immediately a REL message is returned.

I searched for error messages in /var/log/messages and could not find a 
clue about what is going on. I also asked the provider and they tell me 
that everything looks OK on their side. Then I found out that if I 
disconnected the lines, the spans started to work correctly. The error 
persists a system reboot. Asterisk also does not indicate what the 
trouble is.

When I enabled debug for wct4xxp, the following messages started to show:

Jul  6 11:15:03 server kernel: wct4xxp: LOF/LFA detected on span 2 but 
debouncing for 2500 ms

Jul  6 11:15:04 server kernel: wct4xxp: LOF/LFA detected on span 2 but 
debouncing for 2500 ms

The systems calls a number, then calls another and then does a bridge. A 
symptom that leads me to the sync problem is that when the call goes 
into the bridge with spans 2, 3 or 4, I start getting clicks and the 
call quality goes down. Also of note is that span 1 has always worked 
correctly, even when bridging is between channels in the same span 1.

Another thing that I find odd is the output of dadhi_scan, that 
indicates that syncsrc=0 for all spans. Is that correct?

dahdi_tool indicates that Sync Source is Internally clocked for all spans.

I have installed Rev 8852 of dahdi-complete without success. The system 
is CentOS 2.6.18-164.15.1.el5PAE.

Here is the output of wct4xxp startup and dahdi_cfg:
