The TDM411B is a TDM410 card with 1 FXO and 1 FXS module attached and no echo cancellation module (VPMADT032).
Used in conjunction with Asterisk and standard PC hardware, one can create a telephony system that includes all of the cutting edge features of a high-quality business PBX.
Using an industry-standard bursting, bus-mastering interface chip that is found within millions of PC systems worldwide, and Digium VoiceBus technology, the TDM411B 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 TDM411B or other Digium analog interface cards.
The TDM411B provides the same functional capacity as the TDM400P, but improves significantly upon its system compatibility and provides the capability of connecting to Digium's hardware-based echo cancellation modules.
The image shown is a TDM410E card with 2 FXS and 2 FXO modules and the optional echo cancellaton module.
