Asterisk with FXO/FXS interface cards

FXO/FXS interface cards

The Wildcard X100P is an FXO device which will use fxs signalling with Asterisk.
The Wildcard S100U is an FXS device which will use fxo signalling with Asterisk.
The Wildcard TDM400P may have a combination of FXO and FXS modules installed in its four slots. Note that the Wildcard TDM400P may be referred to by different names according to how many modules and what kind of modules are installed on it. If it has one FXS module on it then it is called TDM10B. If it has two FXS modules then it is TDM20B and so on. TDM400P is sometimes used to refer to just the board with no modules on it.


Configuration for the Wildcard X100P:

fxsks=1: if you have one Wildcard X100P installed
fxsks=1-2: if you have two Wildcard X100P cards installed
fxsks=1-3: if you have three Wildcard X100P cards installed, and so on.

Configuration for the Wildcard S100U:

fxoks=1: for one card
fxoks=1-2: for two cards
fxoks=1-3: for three cards, and so on.

Configuration for the Wildcard TDM400P:

If your card is a TDM10B (one FXS module), put: fxoks=1
If your card is a TDM20B (two FXS modules), put: fxoks=1-2
If your card is a TDM30B (three FXS modules), put: fxoks=1-3
If your card is a TDM04B (four FXO modules), put: fxsks=1-4
If your card has modules FXO, FXO, FXS, FXS (in that order), put:
fxsks=1-2
fxoks=3-4
If your card has modules FXS, FXO, FXO, FXS (in that order), put:
fxoks=1,4
fxsks=2-3
If your card has modules FXS, (empty), FXO, FXS (in that order), put:
fxoks=1,4
fxsks=3
If you have one Wildcard TDM40B and one Wildcard TDM22B installed, put:
fxoks=1-4 (for the TDM40B)
fxsks=5,8 (for the two FXO modules on your TDM22B)
fxoks=6,7 (for the two FXS modules on your TDM22B)
NOTE: the names are reversed. For FX0 modules you use fxsks= and for FXS modules you use fxoks=
