24 port modular analog PCI-Express x1 card, no interfaces.
The Digium AEX2400E is a full-length PCI-Express 1.0-compliant modular gateway card for connecting analog telephone stations and analog POTS lines through a PC. It supports a combination of up to six quad port station or trunk modules for a total of 24 lines. AEX2400E includes the VPMADT032 Echo cancel module.
The quad trunk and quad 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 AEX2400 interface cards.
Note: The 12V power connector is required for the operation of station FXS modules. It is not required for the operation of trunk FXO modules
