RAD Unveils Resilient Fast Ethernet Ring Technology With Under 50 Millisecond Carrier-Class Restoration Capability.Business Editors, Technology Writers TEL AVIV Tel Aviv (tĕl əvēv`), city (1994 pop. 355,200), W central Israel, on the Mediterranean Sea. Oficially named Tel Aviv–Jaffa, it is Israel's commercial, financial, communications, and cultural center and the core of its largest , Israel--(BUSINESS WIRE)--Nov. 13, 2002 RFER RFER Residual Frame Error Rate Offers Backbone-Like Solution at Access Network Costs for Metro Enterprise Ring or Daisy-Chain Topologies RAD Data Communications RAD Data Communications (also known as "RAD") is a privately held corporation, based in Tel Aviv, Israel, that designs and manufacturers specialized networking equipment. It was founded in 1981 by Zohar Zisapel and his brother, Yehuda. has announced that it has developed a new technology incorporated in its Megaplex data/voice multiplexer that provides self-healing capabilities on 100 Mbps Fast Ethernet An earlier name for 100Mbps Ethernet. See 100Base-T. (networking) Fast Ethernet - A version of Ethernet developed in the 1990s(?) which can carry 100 Mbps compared with standard Ethernet's 10 Mbps. It requires upgraded network cards and hubs. fiber or copper rings. RAD's unique Resilient Fast Ethernet Ring (RFER) carrier-class technology can re-route traffic within 50 milliseconds in case of link failure on any segment of the ring. This enables enterprises, campuses, power companies, transportation companies and utilities to create a highly reliable network using dark fiber or dry copper in a ring topology ring topology - ring network . Survivability sur·viv·a·ble adj. 1. Capable of surviving: survivable organisms in a hostile environment. 2. That can be survived: a survivable, but very serious, illness. is further enhanced by RFER's modular, scalable support for multiple rings, which eliminates the risk of a single point of failure. Resilient Fast Ethernet Ring uses VLANs to overcome the storming problems that occur when attempting to broadcast over Ethernet rings or when a packet is assigned an incorrect address. Robust Like a Backbone Application But at Access Network Costs RFER is implemented in the new ML-IP(TM) module for RAD's popular Megaplex(TM) family of modular integrated access multiplexers. The ML-IP is an Ethernet uplink module with up to 8 Mbps uplink capacity that can be ordered with either 10/100BaseT or 100BaseFx interfaces with 50-millisecond protection, and serves as the main link to the IP network. The Megaplex-based network can support up to 40 E1 lines in a ring or daisy-chain topology. As is the case with SDH (Synchronous Digital Hierarchy) The European counterpart to SONET. See SONET. SDH - Synchronous Digital Hierarchy , RFER allows a total separation between rings, ensuring that a failure in one particular point will not bring down the entire network. "This robust network topology See topology. functions like a backbone solution," explains Ami Sofer sofer or sopher In Judaism, a scholar-teacher of the 5th–2nd centuries BC who transcribed, edited, and interpreted the Bible. The first sofer was Ezra, who, with his disciples, initiated a tradition of rabbinical scholarship that is still central in , Megaplex Product Line Manager at RAD Data Communications, "but is available at access network costs." EANTC EANTC European Advanced Networking Test Center Tested and Certified This application has been tested and certified for service resilience and voice quality by the Berlin-based European Advanced Networking Test Center (EANTC). Results of testing performed at EANTC's labs confirmed that the ML-IP showed superb service resilience and quality for voice connections, that E1 TDM (Time Division Multiplexing) A technology that transmits multiple signals simultaneously over a single transmission path. Each lower-speed signal is time sliced into one high-speed transmission. traffic was always properly prioritized and that the re-routing time for voice trunks exceeded requirements in all tests. Boosts TDMoIP Capabilities The ML-IP module also supports RAD's innovative TDM over IP (TDMoIP) technology, which transparently delivers legacy services over IP/Ethernet networks. With the ML-IP, the Megaplex empowers RAD's TDMoIP solutions with its vast variety of interfaces for voice and high and low speed data, its high port density and its excellent price per port performance. The versatile Megaplex platform is therefore the perfect addition to underpopulated next generation networks, allowing the transmission of all legacy services over IP. The Megaplex is standards compliant, ensuring compatibility in multivendor environments worldwide.
