I just installed a TE820 octal span T1 card, and it’s not showing up in dahdi_hardware output. This was installed into a test machine that already has a TDM800P card in it, and that one is showing up and working fine. Is there some kernel module that I’m missing?

This is on a FreePBX 1.817.210.58 install – I’m not sure what the dahdi tools version is.

  • Support for the TE820 was added to the wct4xxp driver in DAHDI-Linux v2.6.0. DAHDI-Linux 2.6.1 is the latest version. I bet updating DAHDI-Linux and DAHDI-Tools is all you need to do.

  • I checked the version and it looks like it is up to date

    [root@dozer2 dahdi]# asterisk -rx ‘dahdi show version’
    DAHDI Version: 2.6.1 Echo Canceller: HWEC
    [root@dozer2 dahdi]# modinfo -F version dahdi
    [root@dozer2 dahdi]# cat /sys/module/dahdi/version

    If you have Asterisk running you can get the version like:

    # asterisk -rx ‘dahdi show version’
    DAHDI Version: v2.6.1 Echo Canceller: HWEC

    You can see which version is installed in the modules (sitting on the disk, not necessarily loaded into the running kernel) directory like:

    # modinfo -F version dahdi

    You can see which version is actually loaded in the kernel like:

    # cat /sys/module/dahdi/version

    And I’m with you on this one…
