                        | The Digium AEX410 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 Digium's Asterisk software and  standard PC hardware, one can create a telephony environment that  includes all of the sophisticated features of a high-end business  telephone system.
 
 Using an industry-standard bursting,  bus-mastering interface chip that is found within millions of PC systems  worldwide, and Digium VoiceBus technology, the TDM410 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. Includes hardware echo  cancellation module that 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 AEX410 or other Digium analog interface cards.
 
 Note: The 12V power connector is required for the operation of FXS modules. It is not required for the operation of FXO modules.
