RAD Demonstrates Next Gen Access Solutions in Europe


RAD Data Communications has successfully demonstrated three advanced Ethernet access applications at Europe's first public Carrier Ethernet interoperability event, being held this week at the Carrier Ethernet World Congress in Berlin.

As Ethernet services grow in sophistication to include different applications and hard SLA requirements, the greater will be the need for an intelligent access device to provide end-to-end service control, states Yacov Cazes, Director of Product Management at RAD Data Communications.

At this year's Carrier Ethernet World Congress, RAD is demonstrating how Ethernet access can provide VoIP, video and data, each defined with a different traffic prioritization allowing for end-to-end SLA guarantees, Cazes explains. These services were also provided across different access technologies such as fiber Ethernet and PDH/SDH while sharing the same VPN. he continues.

"We also demonstrated TDM emulation over Ethernet, showing that an Ethernet backbone can provide transport to legacy TDM services with voice quality as high as we have come to expect from TDM systems."

Six different RAD products are integrated into the interoperability demonstration: the ETX-102 and ETX-202 Ethernet Network Termination units (E-NTUs), the Egate-100 Ethernet-over-STM-1/OC-3 Gateway, the Gmux-2000 Central Office TDM-over-IP (TDMoIP) Gateway, the IPmux-14 TDMoIP Gateway, and the RICi-8E1/8T1 Intelligent Converter.

Twelve vendors, including RAD, are demonstrating interoperability and scalability of Carrier Ethernet implementations, including E-Line (point-to-point) and E-LAN (multipoint) business applications, plus residential triple play applications including voice over IP and video broadcasting traffic supplied by CPE devices and emulators.

The other participants are Actelis, Agilent Technologies, Alcatel, Cisco Systems, Ixia, Riverstone Networks, Shenick, Siemens, Spirent Communications, Stratex Networks, and T-Pack.

The event was organized by the European Advanced Networking Test Center (EANTC), supported by T-Systems, and sponsored by the Metro Ethernet Forum. The demonstration showcases the results of a private hot-stage event that occurred last week at EANTC realizing residential and business Ethernet services over a protected, Quality-of-Service enabled, multi-vendor Carrier Ethernet network.
