ADTRAN supplies Walnut Communications with multiservice access platform

JULY 27, 2009 -- The networking technology provider enables TDM delivery over a next-generation Ethernet access network with its Total Access 5000 MSAP.

JULY 27, 2009 -- Walnut Communications, serving west central Iowa, has selected the Total Access 5000 multiservice access and aggregation platform (MSAP) from ADTRAN Inc. (search Lightwave for ADTRAN), provider of next-generation networking products, for next-generation access and Ethernet transport throughout its network.

Walnut will utilize ADTRAN's enhanced Pseudowire Emulation Edge to End (PWE3) technology via the MSAP for TDM service delivery and Ethernet transport over fiber. This will allow Walnut Communications to transition its access infrastructure to a next-generation architecture, while maintaining the ability to fully support TDM T1 applications where needed. Walnut will also leverage the Total Access 5000's eSHDSL capabilities to provide high-bandwidth services to local businesses using Ethernet in the First Mile (EFM) for Ethernet service delivery.

"Our plan was to select an Ethernet-based multiservice platform to start our transformation from legacy TDM to an all-Ethernet network," says Brian Trader, IP technician, Walnut Communications. "There were a number of legacy SONET-based systems as well as Ethernet-only systems, which did not fit the bill. ADTRAN's Total Access 5000 was the only true Ethernet MSAP that addressed all of our needs in a carrier-class chassis design. With the Total Access 5000 we can address hi-caps, business needs, and eventually add POTS and ADSL2+, as we displace our legacy network. Being able to support all of these services from a single platform saves us operational expenses over the long haul."

The MSAP bridges the gap between existing and next-generation networks. With an all-Ethernet core, the ADTRAN platform supports both legacy and emerging service interfaces over copper and fiber. The scalable Ethernet architecture allows carriers to use the Total Access 5000 to more economically address both legacy and next-generation services while providing a seamless path toward a converged network.

"Walnut Communications needed a unique and innovative solution to help them transition to next-generation technologies without stranding an established customer base, and ADTRAN delivered with the Total Access 5000," says P. Steven Locke, vice president of sales, service providers, ADTRAN Carrier Networks Division.
