[asterisk-users] Zaptel / TDM400P card stopped working

[Langdon Stevenson]

Hi

I have a Dell PE2300 with a Digium TDM400P line card in it (with one 
module to handle an inbound phone line).  This is running on a Fedora 8 
system with Asterisk 1.4.21.2-1.fc8

This system has been working nicely for about 12 months.  After a recent 
move of office and relocation of the server Asterisk is back on line, 
but the TDM line card has stopped working.

I have spent half a day working through Google search results, but no 
luck so far.


The command:

   lspci -v

produces:

<snip>

   02:0a.0 Network controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN
   interface
     Subsystem: Unknown device b1d9:0001
     Flags: bus master, medium devsel, latency 32, IRQ 5
     I/O ports at e400 [size=256]
     Memory at f9ffd000 (32-bit, non-prefetchable) [size=4K]
     Capabilities: [40] Power Management version 2
     Kernel modules: hisax


The IRQ is not in use by any other device, so there is no conflict (this 
seems to be a common problem).  The card has always been detected as a 
Tiger3XX.  What stands out here to me is:

     Kernal modules: hisax

I don't believe that this was the case when I first installed the card 
(but it was over a year ago, so I may be wrong).  The hisax driver is 
blacklisted in /etc/modprobe.d/blacklist.


The command:

   lsmod

produces:

The command:

   ztcfg -v

produces:

   Notice: Configuration file is /etc/zaptel.conf
   line 0: Unable to open master device '/dev/zap/ctl'

   1 error(s) detected


The command:

   ls -al /dev/ | grep zap

produces nothing



So, I am left wondering what has changed and why the Zaptel drivers are 
no longer loading.

Can anyone suggest to me how I might go about troubleshooting this issue?
