Roby Technology Co., Limited TDM800E 4 FXO+4 FXS PCI-E Low Profile telephone accessory

PCIe Asterisk Card for IP PBX

The Roby Technology TDM800E is a PCI Express x1 analog telephony board that provides four FXO ports for PSTN trunk connections and four FXS ports for analogue handsets. It is designed for system integrators and small-business administrators who build Asterisk, Issabel or FreePBX appliances on standard PC hardware.

Low-profile fit for 2U servers

The half-height bracket allows installation in 2U rackmount chassis where full-height cards cannot fit. Buyers who need more than eight analogue ports or who require digital PRI, BRI or pure SIP trunking without analogue interfaces should look at alternative cards.

Four FXO plus four FXS ports

The decisive specification is the eight-port analogue mix: four FXO ports connect to the public telephone network and four FXS ports connect to standard analogue phones, defining the maximum simultaneous analogue calls the appliance can handle.
