Analog card configuration

Limitations

  • Wazo does not support hardware echocanceller on the TDM400 card. Users of TDM400 card willing to setup an echocanceller will have to use a software echocanceller like OSLEC.

Verifications

Verify that one of the {wctdm,wctdm24xxp} module is uncommented in /etc/dahdi/modules depending on the card you installed in your server.

If it wasn't, do again the step load_dahdi_modules

Note

Analog cards work with card module. You must add the appropriate card module to your analog card. Either:

  • an FXS module (for analog equipment - phones, ...),
  • an FXO module (for analog line)

Generate DAHDI configuration

Issue the command:

dahdi_genconf

Warning

it will erase all existing configuration in /etc/dahdi/system.conf and /etc/asterisk/dahdi-channels.conf files !

Configure

DAHDI system.conf configuration

First step is to check /etc/dahdi/system.conf file:

  • check the span numbering,

See detailed explanations of this file in the system_conf section.

Below is an example for a typical FXS analog line span:

# Span 2: WCTDM/4 "Wildcard TDM400P REV I Board 5"
fxoks=32
echocanceller=mg2,32

Asterisk dahdi-channels.conf configuration

Then you have to modify the /etc/asterisk/dahdi-channels.conf file:

  • remove the unused lines like:

    context = default
group = 63
  • change the context and callerid lines if needed,
  • the signalling should be one of:
    • fxo_ks for FXS lines -yes it is the reverse
    • fxs_ks for FXO lines - yes it is the reverse

Below is an example for a typical french PRI line span:

; Span 2: WCTDM/4 "Wildcard TDM400P REV I Board 5"
signalling=fxo_ks
callerid="Channel 32" <4032>
mailbox=4032
group=5
context=default
channel => 32

Next step

Now that you have configured your PRI card:

  1. you must check if you need to follow one of the analog_card_specific_conf sections below,
  2. then, if you have another type of card to configure, you can go back to the configure your card <card_configuration> section,
  3. if you have configured all your card you have to configure the interco_dahdi_conf in the web interface.

Specific configuration

FXS modules

If you use FXS modules you should create the file /etc/modprobe.d/xivo-tdm and insert the line:

options DAHDI_MODULE_NAME fastringer=1 boostringer=1

Where DAHDI_MODULE_NAME is the DAHDI module name of your card (e.g. wctdm for a TDM400P).

FXO modules

If you use FXO modules you should create file /etc/modprobe.d/xivo-tdm:

options DAHDI_MODULE_NAME opermode=FRANCE

Where DAHDI_MODULE_NAME is the DAHDI module name of your card (e.g. wctdm for a TDM400P).
