Astribank
Xorcom has developed a revolutionary concept in telephony interfaces for Asterisk systems called Astribank XPP Technology. Using USB 2.0 ports to connect to any Asterisk server, Astribank eliminates the requirement for a PCI (E1/T1) card, and even for PCI slots. It is a versatile and powerful channel bank that was specifically designed for the Asterisk IP-PBX and supports all the common telephony lines and trunks: FXS, FXO, BRI, PRI and R2. The Astribank driver is a part of the standard Asterisk distribution. With Xorcom Rapid Live CD™, a fully operational Asterisk server with pre-configured FXS, FXO, BRI, PRI and R2 ports can be up and working in less than 3 minutes!
Astribank awarded "Best in Show" at Internet Telephony Expo.
Astribank, Xorcom's innovative USB-connected channel bank specifically designed for Asterisk, was awarded "Best of Show" in the "Open Source Solution" category at the IT Expo held recently in Los Angeles.

Why is USB the Ideal Interface?
The USB 2.0 interface provides a theoretical speed of 480,000,000 bits per second. A typical uncompressed phone conversation uses about 64,000 bits per second per direction, plus some overhead; in total less than 200,000 bits per second per phone call is used. Thus, the theoretical concurrent number of conversations that the USB 2.0 interface can handle is 480,000,000 divided by 200,000: roughly 2,400 calls for a single USB 2.0 port.This is a theoretical number, of course, and the typical host processor will not be able to handle this amount of concurrent calls, but it gives a clear answer to the question: "Can the USB port support heavy telephony traffic with multiple Astribanks?"
Connecting multiple Astribank units to a single USB 2.0 port is easy: simply use a USB 2.0 Hub to connect many Astribank units.
