RAD Highlights its Legacy Migration Portfolio at CommunicAsia

Hybrid SDH and PSN Access Solutions Enable Seamless, Economical Transition to Next Generation Communications

Data Communications will be featuring at CommunicAsia 2011 in Singapore its complete legacy migration portfolio for carriers, service providers, enterprises, transportation networks, and public utilities. The portfolio fully addresses the challenges they face in migrating to next-generation packet switched networks (PSNs) and services with flexibility, efficiency and carrier-class reliability.

“While many carriers and private operators are migrating their networks to packet technologies to lower costs and support IP-based services, there remains an enormous installed base of devices that use TDM, analog or low speed data connections,” notes Ofer Rachman, General Manager of RAD Far East. “At the same time, the rapid introduction of Ethernet equipment has created a special challenge for network operators, who maintain extensive legacy TDM infrastructure and need to economically manage a myriad of interfaces, protocols, topologies, and media,” he adds. “RAD’s legacy migration portfolio alleviates the CapEx and OpEx pains associated with the transformation to IP by simultaneously supporting multiple network generations,” Rachman continues. “It also allows continuity for legacy services, while ensuring service quality and ultra-low latency for critical applications over new Ethernet, IP or MPLS networks.”

Harnessing its multidisciplinary expertise in TDM technology as well as its industry leadership in Carrier Ethernet access to combine extensive support for legacy services with future-proof Ethernet capabilities, RAD’s legacy migration product lineup includes multiservice multiplexers and access nodes, fiber multiplexers, SHDSL Ethernet extenders, broadband wireless radios, and TDM pseudowire gateways. These are enhanced with a central-site platform for grooming, aggregation, cross-connect, or transparent delivery functionality. Supporting broadband access rates over copper DSL, PDH, SDH, fiber, or wireless media, the devices provide system solutions with unified management.

Lowering Transition Costs and Ensuring Smart Communications over Packet

By lowering the number of network elements that need to be maintained and managed, RAD’s legacy migration solutions eliminate the CapEx hikes and increased burden to network operations that are related to TDM and PSN co-existence. The hybrid access devices are also instrumental in reconciling required on-going investment in SDH equipment with long-term decommissioning plans, as they remain in place even after the network is replaced to packet technology. Furthermore, RAD’s solutions are designed to provide SDH-level service assurance in a PSN environment, including low end-to-end delay, high availability and resiliency, differentiated quality of service, and Ethernet OAM (Operations, Administration and Maintenance).

“RAD technology offers network engineers and purchasing managers the peace of mind that comes with durability, reliability and flexibility,” Rachman concludes. “Our entire legacy migration portfolio is comprised of standards-compliant solutions that deliver consistent and stable performance so as to require minimal on-site maintenance, yet are highly versatile to allow network operators the freedom to choose the migration path that best fits their needs.”
