Overview
The TDM400P card is a device used for connecting your phone network
to the PSTN (Public Switched Telephone Network) world. This is
accomplished through phone lines connected to the FXO (Foreign
Exchange Office) ports and phones connected via the FXS (Foreign
Exchange Station) ports. The card allows Asterisk PBX software to
connect to your phone network, creating a Small Office Home Office
(SOHO) telephony environment. See Figure 1 for an example of the
card’s primary application.
