Redfone foneBRIDGE2-EC Quad T1/E1 Ethernet Bridge with EC
Asterisk? T1/E1 Redundancy, High Availability and now Carrier Class Echo Cancellation in an economical
package.
foneBRIDGE2-EC 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/PBX systems.
foneBRIDGE2-EC eliminates the need to install proprietary TDM hardware cards in approved compatible server configurations. Instead, foneBRIDGE2-EC terminates T1/E1 PRI lines on the trunk side and provides direct Ethernet communication to a network of Asterisk 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.
Failover & Asterisk HA Enabled
- High-Availability through rapid failover capabilities ensures your critical telephony
services are always on and available
Flexible Configuration
- Configurable on a per-port basis, foneBRIDGE2 allows you to mix multiple telephony
standards on a single deployment
Solid State Embedded Appliance
- No moving components
- Low heat and power consumption
- High MTBF (mean time before failure)
Carrier Class Echo Cancellation
- ITU G.168 Compliant
- 128ms of echo tail on over 100 concurrent channels
- Qualified as Toll Quality by AT&T KEY FEATURES
Target Applications
- T1/E1 PRI Trunk termination
- Legacy PBX-to-Asterisk integration
- High-Availability/Failover Asterisk clusters
