New Low Cost and Compact Single Port T1/E1 foneBRIDGE2

Redfone foneBRIDGE2-EC Single Port T1/E1 to TDMoE with onboard Echo Cancellation

T1/E1 Redundancy, High Availability and Simplified Installation in an Economical Package

Overview

Designed as a low-cost alternative to old fashioned PCI based cards, the new single port foneBRIDGE2 is a T1/E1-to-Ethernet Gateway. It is an integrated black-box "appliance" designed to streamline installation and enable redun-dant design of Asterisk based VoIP systems. foneBRIDGE2 eliminates the need to install proprietary TDM PCI hardware cards in approved or compatible server configurations. Instead, foneBRIDGE2 terminates T1/E1 lines on the trunk side and provides direct Ethernet commu-nication to a network of PBX servers using 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.
