Roby Technology Co., Limited TDM410P 1 FXO 3 FXS PCI Telephone Accessory

PCI telephony card for Asterisk PBX builds

This new PCI adapter adds one FXO port for a PSTN line and three FXS ports for analog handsets, letting a standard PC run an IP PBX or VoIP gateway with Asterisk, DAHDI, FreePBX, Issabel, VitalPBX or FreeSWITCH. The red FXO module connects the public network while the green FXS modules attach ordinary telephones.

Suits integrators building a low-cost analog trunk

Installers who need more than one PSTN line or more than three analog stations should look elsewhere, as the fixed 1 FXO and 3 FXS layout cannot be expanded. Systems that require a PCI Express interface or digital PRI/BRI interfaces are also not addressed by this board.

Single PCI slot provides the only connection

The card fits a legacy PCI bus and relies entirely on that slot for power and signalling; no additional connectors or external power are used. Verify that the target machine has an available PCI slot before ordering.
