Digium TDM404B Analog Telephony Card

The Digium TDM404B is a quad FXO PCI Card for use with open source telephony platforms like Asterisk. Using Digium's Asterisk® software and standard PC hardware, one can create a telephony environment that includes all of the sophisticated features of a high-end business telephone system.

Digium TDM404B Analog Telephony Card Overview

The Digium TD404B is built atop the Digium® TDM410P, a half-length PCI 2.2-compliant modular gateway card for connecting analog telephone stations and analog POTS lines through a PC. It supports a combination of up to four station or trunk modules for a total of 4 lines. Using an industry-standard bursting, bus-mastering interface chip that is found within millions of PC systems worldwide, and Digium VoiceBus™ technology, the Digium TDM404B eliminates the requirement for external gateways, with industry-leading performance and price. The trunk and station modules are interchangeable, allowing the creation of any combination of interfaces. The optional hardware echo cancellation module provides 1024 taps (128 milliseconds) of echo cancellation for superior voice quality on both trunk and station interfaces. Scaling of this solution is accomplished by adding additional TDM410 or other Digium analog interface cards.

Note: The 12V power connector is required for the operation of FXS modules. It is not required for the operation of FXO modules.
