Digium TDM2406B (24 FXO Ports)

Bus Type: Full-length PCI 2.2-compliant

Using an industry-standard bursting, bus-mastering PCI interface chip that is found within millions of PC systems worldwide, and Digium's patent-pending VoiceBus technology, the TDM2406B eliminates the requirement for separate channel bank and T1 interface cards, at an industry-leading price. The quad-FXO and quad-FXS modules are interchangeable, allowing the creation of any combination of interfaces. The optional hardware echo cancellation module provides 256 taps of echo cancellation for superior echo cancellation on both FXO and FXS interfaces. Scaling of this solution is accomplished by adding additional TDM2400P series cards.

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