ADTRAN, Inc. (NASDAQ: ADTN) announced Tuesday that it is demonstrating the first complete, last-mile deployment solution for the industry's newest DSL standard, G.shdsl, using the Total Access System. G.shdsl is the draft ITU standard (G.991.2) for Symmetric High Bit-rate Digital Subscriber Line (SHDSL) technology. Carriers deploying G.shdsl will be able to deliver symmetric data rates up to 2.3 Mbps over a single copper pair at distances 15 - 20% greater than current 2B1Q-based SDSL technology. G.shdsl's spectral compatibility means no binder group restrictions, making it much easier for carriers to deploy. Also, G.shdsl works well over existing copper lines with all impairments and impedances, reducing the need for costly truck dispatches.
ADTRAN's G.shdsl deployment solution consists of two components: Total Access 3000 configured as a DSL Access Multiplexer (DSLAM) with ADTRAN's new 8-port G.shdsl access module, and Total Access 850 Integrated Access Device (IAD). The Total Access System with G.shdsl provides carriers a flexible, modular, end-to-end solution that extends DSL reach, is spectrally compatible with other DSLs, and is interoperable for guaranteed operation in multivendor environments.

"We're pleased to offer a G.shdsl solution to the market," said Kevin Morgan, Director of Product Management for ADTRAN's Carrier Networks Division. "The potential of this new, high-speed, symmetric technology is becoming increasingly attractive to carriers. Using ADTRAN's Total Access System for G.shdsl deployment allows the carrier to capture more of the lucrative small to medium-sized business market."
