Title: No Dial tone on FXS ports
Post by: compsos on July 13, 2009, 02:47:47 PM

Hi S
Not sure if this only started after upgrading to 2.3.1-20 or it was just going to start at the same time.

Basically a TDM422B card seems to be only working a single FXO port on port 1. The 2nd FXO deflects all incoming calls as busy, a internal call to any analogue phone on the FXS ports goes straight to message bank. The phones have no dial tone.

The only clue I have found is in the console

Code: [Select]

[Jul 13 22:35:00] WARNING[31878]: channel.c:3210 ast_request: No channel type registered for 'DAHDI'
[Jul 13 22:35:00] WARNING[31878]: app_dial.c:1272 dial_exec_full: Unable to create channel of type 'DAHDI' (cause 66 - Channel not implemented)
  == Everyone is busy/congested at this time (1:0/0/1)
The dahdi_cfg -vv did throw

Code: [Select]

DAHDI Tools Version - 2.1.0.2
Notice: Configuration file is /etc/dahdi/system.conf
line 15: Syntax error. Should be <keyword>=<value>
line 17: Syntax error. Should be <keyword>=<value>
But issuing /usr/bin/dos2unix /etc/dahdi/system.conf seems to have fixed that and dahdi loads OK. How can I test/prove the 3 (1 FXO & 2 FXS) modules that now seem suspect?
Thanks

OK Got the extension FXS Ports back but still the 1 FXO port reports busy. The module is a X100M card. Is there a way to reset this card? I have shut down and removed the module card and reseated but made no difference.

with the card fitted and running, at the asterisk console do

dahdi show channels


also - at the linux console 

cat /proc/dahdi/1

should show the card channels

Usually its the FXS channels which give trouble, not the FXO

I was unable to see any difference between the working one and the one rejecting all calls

           4 WCTDM/4/3 FXOKS (In use)  (EC: MG2)

Both say they are "Onhook" but all calls on card 2 are instantly rejected as busy with no activity on the console. This is the 2nd time a card in this position has failed with no warnings or messages. It would be great to be able to pin point the cause.
Thanks

Hard to know what to suggest.  You could try swapping the daughterboards around to see if the fault follows the board.  If it does then you probabaly need a new daughterboard.

Over the years we have had quite a few TDM FXO modules blow, usually as a result of some kind of surge on the phone line (we've had a few go during thunder storms).

Thanks Jeff
I have ordered new daughterboard. Just strange how the last one to fail was in the same position.
