Astribank™ – USB-connected telephony interfaces (channel bank) for Asterisk
Astribank is a revolutionary concept in telephony interfaces for Asterisk systems. 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 USB 2.0 interface provides a theoretical speed of 480 Mbits per second, which for typical uncompressed phone conversations translates to roughly 2,400 calls per port. Astribank is available in a variety of models, all based on combinations of the following types of modules: FXS, FXO, PRI (E1 and T1), CAS, R2 and BRI ISDN, to match user specifications. Connections for peripheral devices, such as alarms and door openers, are also supported. The USB architecture employed by Xorcom products affords many advantages, including the ability to build large systems that support hundreds of analog extensions, rapid set-up and easy maintenance.
Multiple Astribank units may be connected to a single server using different USB 2.0 ports, or a USB 2.0 hub, or a USB 2.0 PCI card, to easily create a telephony system that supports hundreds of analog extensions. By providing support for MWI (Message Waiting Indicator) in analog phones, Astribank becomes an especially practical solution for large commercial implementations, such as hotels and assisted living facilities. Supported options include utilities for disaster recovery and high availability.
