The FXO module FXO-100 allows the Asterisk card card to terminate
analog telephone lines (POTS). Because of the modular design,
a user can activate additional ports at any time with more FXS
or FXO daughter cards.
The FXO module passes all the call features
any standard analog telephone line will support.
It supports : TDM400P/TDM410p/AEX410/X100P
