Quick Overview

The Digium TDM2422B card is a full-length, 32-bit, 33MHz, PCI 2.2-compliant card that includes 2 quad-port FXO and 2 quad-port FXS modules for a total of 8 FXO ports and 8 FXS ports.

Digium TDM2422B Information:


The TDM2400P takes the place of an expensive channel bank and brings the system price point to a low level. By using X400M and S400M modules with the TDM2400P, one can create a solution with support for a range of telephones.


To scale this solution, simply add additional TDM2400P cards populated with modules. The S400M FXS module allows the TDM2400P card to terminate four analog telephones per module. Because of the modular design, a user can activate additional ports at any time with more S400M daughter cards. The S400M module passes all the call features any standard analog telephone line will support.
