foneBRIDGE2 Overview

foneBRIDGE2 is a T1/E1 PRI-to-Ethernet Bridge. It is an integrated black-box "appliance" designed to streamline
installation and enable redundant design of Asterisk based VoIP systems. foneBRIDGE2 eliminates the need to install proprietary TDM hardware cards in approved/compatible server configurations. Instead, foneBRIDGE2 terminates T1/E1 PRI lines on the trunk side and provides direct Ethernet communication to a network of Asterisk serversusing native Asterisk TDMoE formats and utilities. Engineered around our unique high-speed SoC
(System-on-Chip) TDMoE engine, foneBRIDGE2 provides low-latency delivery of your critical voice traffic and rapid switching to backup server nodes during fail over operations.
