Turin Networks announces SONET/SDH and Ethernet edge system for metro access networks

June 21, 2004 Petaluma, CA--Turin Networks, a developer and supplier of multiservice transport platforms, tpday announced the TraverseEdge 100 (TE-100), a compact, next-generation SONET/SDH and Ethernet edge system designed specifically for carriers.

June 21, 2004 Petaluma, CA--Turin Networks, a developer and supplier of multiservice transport platforms, today announced the TraverseEdge 100 (TE-100), a compact next-generation SONET/SDH and Ethernet edge system designed specifically for carriers. It's the first product to economically push SONET/SDH to the edge while offering the redundancy and Ethernet features demanded by carriers, according to the company.

The TE-100 allows efficient and cost-effective delivery of packet and TDM services over existing SONET/SDH networks in a variety of applications. The compact, two rack-unit high design is optimized for deployments in metro access rings, or as an end-node in multi-tenant units, outside plant environments, or in customer locations. The TE-100 was designed to work seamlessly with Turin Networks' metro transport network solution, the Traverse Multiservice Transport Platform.

The TE-100 is differentiated from competing platforms by going beyond supporting standard SONET/SDH facilities protection, to also provide optional equipment protection for the high-speed optical network interfaces. Hardware redundancy is a mandatory feature for many carriers that ensures network availability in the event of a device failure.

The TE-100 supports key standards, including Generic Framing Procedure, Link Capacity Adjustment Scheme and both Low-order and High-order Virtual Concatenation, which enable Ethernet traffic to be transported more efficiently over the SONET/SDH infrastructure. In addition, the TE-100 is the first product in its class that integrates Ethernet switching functions to aggregate and manage traffic at layer 2, and deliver next generation Ethernet services such multi-point virtual private networks with guaranteed service levels.

"The global shift from TDM-based SONET/SDH ADMs to multi-service transport platforms is well underway in the network core. And now Ethernet is driving market dynamics at the network edge, as service providers focus on improving the cost, efficiency, and flexibility of providing mixed TDM and data services. Vendors such as Turin Networks are supporting their customers' evolution to a purpose-built multi-service edge that extends and integrates with their large installed SONET/SDH optical networks in the metro core," said Dana Cooperson, optical networks group and program director at market research and consulting firm RHK. "The TE-100 exhibits the carrier-class and multiservice design characteristics service providers are looking for at the network edge."

Designed as a next-generation edge solution with global reach, the TraverseEdge 100 aggregates a combination of DS-1 or E1, DS-3 or E3, Fast Ethernet and Gigabit Ethernet service interfaces onto dual high-speed SONET OC-3/12/48 or SDH STM-1/4/16 ports. As a carrier-class product, the TE-100's high-speed optical ports support linear and ring topologies with optional 1+1 network protection, and 1:1 equipment protection.
The SONET version of the TE-100 will be available in calendar Q3 of this year, with the SDH version available in Q4.

Turin Networks' flagship Traverse platform provides best-in-class SONET/SDH transport, crossconnect and Ethernet switching capabilities, enabling more than 90 carriers worldwide to seamlessly evolve, streamline and grow their multiservice optical networks. Founded in October of 1999, Turin is led by an accomplished management team and is funded by top-tier venture capital firms as well as corporate and private investors.
