Unless I read the OP's words wrong, the above  is totally incorrect.

If you are going to plug a pstn line into the TDM card, the module
needs to be a "red" module (not green). The green modules are for
telephone sets.

Get a red fxo module, set /etc/zaptel.conf to "fxsks=1" (if the red
module is in slot 1, and then work on the zapata.conf statements.
