Roby Technology Co., Limited TDM410P Echo Canceller Card 2 FXO 2 FXS PCI Telephone Accessory

Analogue voice card with echo cancellation

The Roby TDM410P is a PCI analogue voice card that adds two FXO and two FXS ports to a Linux server running Asterisk, DAHDI, FreePBX, Issabel, VitalPBX or FreeSWITCH. It provides hardware echo cancellation on every channel, so small businesses can build a complete IP-PBX, call centre or VoIP gateway on commodity hardware.

Replaces separate FXO and FXS boards

A single TDM410P removes the need for multiple single-port cards and the driver conflicts they introduce. The jump is worth it when you need both PSTN trunk connections and analogue handset extensions in one slot, and when the bundled MG2 echo canceller eliminates the CPU load of software cancellation.

Four concurrent analogue channels

The card handles two incoming PSTN lines and two analogue telephones simultaneously, each with hardware MG2 echo cancellation under DAHDI 2.2.0. It runs out when a site needs more than four analogue ports, digital PRI/BRI interfaces, or a server that lacks a conventional PCI slot.
