Asterisk Based Channel Bank - Astribank™

Astribank is a PSTN channel bank and VoIP telephony system that was especially designed for the Asterisk open source IP-PBX. Astribank uses industry-standard USB 2.0 ports to communicate with the Asterisk server. Housed in an industry-standard 19" rack/wall-mountable chassis, a single Astribank supports up to 32 analog ports, or up to 144 analog and PRI channels.

Benefits of the USB 2.0 Interface

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 Astribank units, an auxiliary system interface, and more.

Modular, Flexible Channel Bank Grows with Your Telephony Needs

A single Astribank USB-connected channel bank supports various combinations of analog and/or digital telephony lines and trunks. Furthermore, the Astribank design allows customers to let the system grow along with their telephony needs. The digital modules support individual software activation of each port (up to four ports per PRI module, and up to eight ports per BRI module). In other words, customers purchasing a single E1/T1 port receive hardware that can support up to four active ports. When required, the additional port(s) can be activated remotely, via a software key. Additional analog modules can also be added as needed (each chassis supports up to four modules of eight analog ports each) for a maximum of 32 analog ports per chassis.
