New Version of RAD’s TDM Pseudowire Gateways Ideal Solution for Utility and Transportation Networks

RAD Data Communications has released version 6 of its IPmux-8 and IPmux-16 TDM pseudowire gateways, which support legacy traffic over IP and Ethernet networks by converting TDM signals into packets using RAD’s patented TDM over IP (TDMoIP®) technology.

 

“Version 6 incorporates daisy-chain capability, a topology that is particularly suited for utilities and transportation networks, such as those maintained by railroads,” explains Ron Agam, Senior Product Line Manager at RAD Data Communications. “Version 6 introduces redundancy, a feature that is critical for protecting end-to-end TDM traffic,” he continued. “In addition, instead of fixed optical ports, version 6 provides up to eight Ethernet ports and SFP ports for better operational flexibility.”

The modular, carrier-class IPmux-8 and IPmux-16 pseudowire gateways employ RAD’s patented TDM over IP (TDMoIP®) technology to convert TDM user traffic data streams into IP packets or MPLS frames for transmission over packet-switched network (PSNs) via an Ethernet uplink. A TDMoIP gateway at the remote side converts the packets back to TDM traffic. These TDMoIP gateways take advantage of the popular new IP/Ethernet/MPLS networks to deliver TDM-based voice, fax, modem, and data services without compromising traditional PSTN quality.

The IPmux devices support legacy PBXs, including proprietary features and signaling. By deploying RAD’s IPmux TDMoIP pseudowire solution, customers can eliminate costly point-to-point E1/T1 and E3/T3 leased lines. TDMoIP is also ideal for running cellular backhaul and international toll bypass over PSNs.

 

The IPmux-8 and IPmux-16 pseudowire gateways offer extended, Layer 2-based, TDM and Ethernet integrated access capabilities. They enable wire-speed bridging between the user LAN and the Ethernet WAN. User port traffic can be rate-limited, tagged and filtered (based on VLAN membership) and double VLAN tagging (VLAN stacking) can be applied to better engineer the network and allow a granular bandwidth capacity offering.

 

Both the IPmux-8 and the IPmux-16 pseudowire gateways support E1/T1 connectivity for any user device with standard E1/T1 interface, alarm detection and insertion along with error statistics, SES/UAS statistics, LOS/AIS physical layer alarms, standard E1/T1 alarms from end-to-end, and remote/local loop test modes. The IPmux-16 pseudowire gateway is also NEBS compliant.
