An FXO (Foreign Exchange Office) Asterisk card is a hardware component used in conjunction with the Asterisk open-source telephony software.
FXO cards are designed to connect analog telephone lines, allowing the Asterisk system to interface with traditional PSTN (Public Switched Telephone Network) lines.
These cards come in various configurations, typically providing multiple ports for connecting analog phone lines to the Asterisk server.
A400 Series can be used for connecting analog telephones and analog POTS lines through a PC. It supports combinations of FXS and/or FXO modules for a total of 4 lines.
A400 Series delivers great voice quality in the telephony systems. With interchangeable FXS/FXO modules, it can eliminate the requirement for separate channel banks or access gateways.
The A400 Series contains 4 module banks. Each bank supports one analog interface. The module banks may be filled with up to 4 FXO or FXS modules enabling the creation of any combination of ports. Scaling of an analog card solution is accomplished by simply adding additional cards.
A400 Series works with Asterisk®, Elastix®, FreeSWITCH™, PBX in a Flash, trixbox®, Yate™ and IPPBX/IVR projects as well as other Open Source and proprietary PBX, Switch, IVR, and VoIP gateway applications.
