Digium AEX404E 4 Port Modular Analog PCI-Express x1 Card with 4 Trunk Interfaces and HW Echo Cancellation (1AEX404EF)

The Digium AEX404E is a half-length PCI-Express x1 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 AEX410 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 additiona l AEX410 or other Digium analog interface cards.

The AEX404E Includes:

• Zero (0) Single Station (FXS) Module (Red)
• Four (4) Single Trunk (FX0) Module (Red)
• One (1) 128ms Hardware Echo Cancellation Module
