##### Analog Interfaces

TDM410 and AEX410 - The TDM410P and AEX410 are modular four-port half-length PCI 2.2 and PCI-Express x1, respectively, cards that supports FXS and FXO station interfaces for connecting analog telephones and analog POTS lines through a PC.

TDM800 and AEX800 - The TDM800 and AEX800 are modular eight-port half-length PCI 2.2 and PCI-Express x1, respectively, cards that support FXS and FXO station interfaces for connecting analog telephones and analog POTS lines through a PC.

TDM2400 and AEX2400 - The TDM2400 and AEX2400 are modular twenty-four port full-length PCI 2.2 and PCI-Express x1, respectively, cards that support FXS and FXO station interfaces for connecting analog telephones and analog POTS lines through a PC.

##### Digital Interfaces

TE122 and TE121 - The TE122 and TE122 are half-length, half-height PCI 2.2 and PCI-Express x1, respectively, single-span E1/T1/J1 PRI/PRA software-configurable interfaces for terminating digital telephony through a PC.
TE205/7, TE210/12 and TE220 - The TE205, TE210 and TE220 are half-length PCI 2.2 5.0V, PCI 2.2 3.3V, and PCI-Express x1 dual-span E1/T1/J1 PRI/PRA software-configurable interfaces for terminating digital telephony through a PC.
TE405/7, TE410/12 and TE420 - The TE405/7, TE410/12 and TE420 are half-length PCI 2.2 5.0V, PCI 2.2 3.3V, and PCI-Express x1 quad-span E1/T1/J1 PRI/PRA software-configurable interfaces for terminating digital telephony through a PC.
HA8 and HB8 - The HA8 and HB8 are half-length PCI2.2 and PCI-Express x1, respectively, modular eight-port EuroISDN BRI and Analog FXS/FXO interfaces for terminating telephony through a PC.
B410P - The B410P is a half-length PCI-2.2 fixed four-port EuroISDN BRI interface for terminating digital telephony through a PC.

##### Packet Interfaces

TC400 and TCE400 - The TC400 and TCE400 are half-length, half-height PCI 2.2 and PCI-Express x1, respectively, codec translation cards for DSP-based translations of patent-encumbered codecs such as G.729a and G.723.1
