FIRST TDM PSEUDOWIRE GATEWAY PRODUCTS THAT SUPPORT ALL INDUSTRY TDM PSEUDOWIRE MODES INTRODUCED BY RAD COMMUNICATIONS
04 June 2007 - RAD Data Communications Ltd

RAD's new TDM pseudowire gateways are unique because they will incorporate a high-performance ASIC chip, developed by RAD, which supports Structure Agnostic TDM over Packet and the two IETF informational RFCs: Circuit Emulation Service over Packet Switched Network, and TDMoIP. 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 RecoverySince 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, 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, 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 ShippedRAD 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.

RAD Data Communications has announced the establishment of a research and development unit in Beijing dedicated to passive optical network technology. This is the company's first R&D facility in China.

'There are many opportunities for deploying PON technology, particularly GPON, in China, and we wanted to be as close as possible to this critical market by designing products based on local know-how,' explains Hugo Silberman, Vice President of Research and Development at RAD Data Communications. 'We have put together an excellent team of engineers who have gained valuable experience in the field and are familiar with customer applications and requirements.'

'Establishing R&D facilities in China is a natural progression for us,' Silberman continues, noting that the company opened sales offices in Beijing and Shanghai in the 1990s and added a local manufacturing plant in 2002.

'The R&D team will initially focus on PON devices but will also be able to broaden its assignment to include additional specialized requirements for the Chinese market and the global market in the years ahead,' reports Silberman.
