Specifically designed to meet the requirements of Competitive Local Exchange Carriers (CLEC) and other VoIP Providers, this compact 19” 1U chassis supports up to 480 digital telephony channels.
Overview
Astribank Multi-PRI: High density T1/E1 in a small footprint
Service providers and other implementations requiring a large number of PRI ports will appreciate the high density E1/T1 Astribank. It supports up to 16 PRI ports for up to 480 E1 channels (or up to 384 T1 channels) in a compact, 19” rack-mountable chassis. This modular, expandable unit features built-in redundancy, as each four-port module works independently, and the entire unit may be powered by Xorcom’s dedicated multiple redundant power supply unit. Hardware echo cancellation is standard for all active ports.

Required DAHDI Drivers
The DAHDI drivers required are the same as those required for the Xorcom Hardware Echo Cancellation add-on.See this document for details.
Capacity (concurrent calls)
30 concurrent calls per active E1 port (e.g., for the XR0111 with 8 E1 ports, the calculation would be: 8x30=240), or 24 concurrent calls per active T1 port (e.g., for the XR0111 with 8 T1 ports: 8x24=192).
Hardware
Interface Integration
E1/T1 PRI, E1 R2, or T1 CAS, which includes:
Full PRI/R2/CAS ISDN support
NT/TE settings for each channel
Indicator lights for active settings and line status, per channel
E1/T1 support (configurable)
