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. The internal design of Astribank is modular, offering a wide variety of FXS, FXO, BRI ISDN and I/O port combinations. Multiple Astribank units may be connected to a single Asterisk server using different USB 2.0 ports, a USB 2.0 hub or USB 2.0 PCI card.
The USB 2.0 interface supplied with the Astribank server guarantees a reliable, extremely high bandwidth, hot-pluggable solution that is not dependent on a PRI PCI card. A single USB 2.0 port can theoretically support over 3,000 concurrent calls. The reliable, industry-standard USB connection eliminates the costly, cumbersome PRI cards that are needed for standard channel bank support, and adds unique features such as reliable fax support, transparent synchronization between Xorcom Astribank units, an auxiliary system interface, and more. Astribank's driver has been included as an official part of Zaptel now DAHDI since release 1.2.4 Feb. 2006, making Astribank integral with Asterisk systems. Today Astribank is tested with Debian, CentOS 5 and trixbox CentOS 4.
