XORCOM XR0056 Astribank is a versatile and powerful channel bank that was specifically designed for the Asterisk IP-PBX. XORCOM XR0056 Astribank extends the functionality of Asterisk-based IP-PBX systems and supports all the common telephony lines and trunks: FXS, FXO, BRI, E1/T1 PRI, T1 CAS and E1 R2. XORCOM XR0056 Astribank connects to the Asterisk IP-PBX server via USB 2.0, thus eliminating the need for an intermediating PCI (the solution used by other channel banks). Software XORCOM XR0056 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 XORCOM XR0056 Astribank is tested with Debian, CentOS 5 and trixbox (CentOS 4). Astribank-based Failover Solution All XORCOM XR0056 Astribank units are capable of supporting TwinStar, Xorcom's failover solution for complete PBX systems. TwinStar is a high availability solution that provides automatic detection of server failure and immediate switching of all telephony functions, including telephony interfaces, to a back-up server. It is compatible with any Asterisk-based PBX system that supports a USB 2 connection (such as: Xorcom XR2000 and XR3000). This quick and automatic failover process keeps downtime to an absolute minimum.
