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.

Questions about this item

Will the TDM410P fit a standard PCI slot?

Yes, the card uses a standard PCI interface for installation in a compatible motherboard slot.

How do I configure the TDM410P with DAHDI on Issabel or FreePBX?

Run dahdi_genconf to generate the configuration, then run dahdi_cfg -vvvv to apply it and verify the channel map shows four channels.

When should I replace the FXO or FXS modules on the TDM410P?

Replace a module if its port stops detecting line voltage or ringing, or if call audio develops noise that persists after re-seating the card.
