RAD Rolls Out Industry-First Implementation of SAToP, TDMoIP and CESoPSN Embedded In a Single TDM Pseudowire Device

New Gateways Are Powered by RAD's High-Performance ASIC Supporting All Industry Standards

Tel Aviv, November 21, 2006: RAD Data Communications, the industry pioneer of pseudowire technology, has announced that it will introduce the world's first TDM pseudowire gateway products that support all industry TDM pseudowire modes at ITU Telecom World 2006, to be held December 4-8 in Hong Kong.

RAD's new TDM pseudowire gateways are unique because they will incorporate a high-performance ASIC chip, developed by RAD, which supports SAToP (Structure Agnostic TDM over Packet) and the two IETF informational RFCs:
CESoPSN (Circuit Emulation Service over Packet Switched Network), and TDMoIP(r) (TDM over IP). In addition, the new devices support HDLCoPSN, an IETF standard, optimizing bandwidth for HDLC based services such as Frame Relay, X.25 and serial data traffic over packet-based networks.

Enables Implementation of the Widest Possible Service Portfolio

"Pseudowire solutions are rapidly becoming a must-have element in carrier portfolios to ensure a complete multiservice offering over packet-based networks," states Ron Agam, Senior Product Line Manager at RAD Data Communications. "Carriers, on the other hand, want the widest possible range of choices in deciding which flavor of TDM pseudowire is best able to support their application," he explains. "For this reason, multi-standard support is high on their checklist of product feature requirements," notes Agam. "Embedding this functionality in hardware offers the advantage of low latency, low delay, low cost, and high-performance processing, avoiding operational downsides associated with software implementations."

Sophisticated Clock Recovery

Since highly accurate TDM clock recovery is the paramount issue for TDM circuit emulation, RAD's third-generation ASIC also incorporates an advanced adaptive clock recovery mechanism, with accuracy of 16 parts per billion (ppb), conforming to G.823 traffic and synchronization specifications for jitter and wander as well as the new ITU-T G.8261 Recommendation, specifying synchronization over packet requirements.

"Delivering carrier-class TDM services requires sophisticated clock recovery technology in addition to pseudowire technology," adds Agam. "This processing is computationally intensive and there is a clear advantage to having the clock recovery algorithm wired into the silicon."

Pseudowires enable carriers and enterprises to run voice, video, and legacy data over packet-switched networks (PSNs), such as Ethernet, MPLS and IP, thereby minimizing network maintenance and operating costs. Transparent connectivity over Ethernet/IP/MPLS maintains all features and functionality of the legacy network, including CAS and CCS signaling.

"Pseudowire technology in the access is win-win-win for incumbent carriers as well as alternative carriers, data service providers and customers of all stripes," Agam says. "It requires no "forklift equipment upgrades" nor staff retraining, and any high-speed Last Mile access network, wireless, DSL, cable, fiber or PON, can be leveraged to deploy traditional leased line services, PSTN access over packet or even cellular backhaul."

More than 50,000 Ports Shipped

RAD first introduced TDMoIP pseudowire technology to the market in 1998 when it launched its first generation IPmux pseudowire gateways. Since that time, the number of TDMoIP ports it has shipped has steadily grown to exceed 50,000, which makes it the leading vendor with TDM-over-packet switched networking equipment successfully deployed in the field.
