Sangoma B501E BRI PCI Express Card.

Newly redesigned and simplified, the Sangoma B500 S/T BRI interface board delivers superior audio quality and scalability. It expands from two to four ports of BRI, with optional telco-grade hardware echo cancellation.

A single Asterisk PCI Express slot hosts the connection for up to 4 ports and ensures common synchronous clocking for all channels with no signalling issues.

The B500 consists of a Remora™ BRI daughterboard mounted on the AFT Asterisk PCIe board. The Remora™ BRI card has 2 sockets, each of which can accept an S/T BRI module. One S/T BRI module has two S/T four wire interfaces, which support TE or NT modes of operation.

The B500 has 4 RJ-45 ports, each port can handle one S/T four wire BRI interface with a single standard Cat-5e shielded twisted-pair cable.


  • Supports 2 to 4 ports; mix TE and NT modes, as required.
  • Support for Asterisk®, FreeSwitch™, as well as other Open Source and proprietary PBX, Switch, IVR, and VoIP gateway applications
  • Fully Asterisk PCI Express compliant, compatible with all commercially available motherboards, proper sharing of Asterisk PCI interrupts
