TDM800P-62 Analog Telephony Card

The Roby Technology TDM800P-62 adds eight analog voice ports to a PC through a PCI slot. Six FXO ports connect to PSTN lines and two FXS ports connect to standard analogue telephones. The card targets installers building an Asterisk-based PBX, call centre or VoIP gateway on a low budget.

Check PCI Slot and Software Stack

Verify the host has a free PCI slot and runs a DAHDI-compatible distribution such as Asterisk, FreePBX, Issabel or VitalPBX. The low-profile bracket fits 2U servers, so confirm chassis height before ordering. No other interface or protocol is supported by this board.

Sustained Operation With MG2 Echo Cancellation

Under continuous call load the onboard DAHDI driver uses the MG2 echo canceller on all eight channels. The FXS ports default to Kewlstart signalling while the FXO ports use Kewlstart for trunk supervision. This configuration remains stable during long-running sessions without requiring proprietary firmware.

Questions about this item

Does the TDM800P-62 card ship with any cables or brackets, or must they be purchased separately?

The supplier data lists only the card with 6 FXO and 2 FXS ports; no cables, brackets or additional accessories are mentioned, so plan to source any required PSTN line cords or low-profile brackets separately.

How do I decide between the 6 FXO / 2 FXS configuration and other port mixes for my Asterisk PBX?

Choose this 6 FXO / 2 FXS version when you need to connect up to six PSTN lines and two analog handsets; other TDM800 models with different FXO/FXS counts exist, so match the port mix to your line and handset requirements.

What does the eight-channel DAHDI map (channels 1–8) mean for actual call capacity on this card?

Channels 1–6 are mapped to the two FXS ports (three channels each) for analog phones, and channels 7–8 map to the six FXO ports for PSTN trunks, giving a maximum of eight simultaneous DAHDI channels in Asterisk.
