The ADTRANTM Total Access® Octal SHDSL module provides high density, low-cost deployment of eight industry-standard SHDSL interfaces. SHDSL is the most func- tional, standards-based Digital Subscriber Line (DSL) technology developed to date. Resulting from the convergence of the best features of traditional DSL technologies, SHDSL incorporates rate/range adapt- ability, spectral compatibility, impairment tolerance, and high-speed symmetric deployment. SHDSL is particularly suited for business-based voice and data applica- tions such as multiple voice-line delivery, Internet access, and remote LAN access.

The Octal SHDSL module is another addition to ADTRAN’s Total Access DSLAM architecture. The Total Access DSLAM utilizes the enhanced System Controller Unit (SCU) and the Cell Switch Module (CSM) configured in the same chassis as ADTRAN’s field-proven Total Access Broadband Platform. The CSM receives and routes ATM traffic from the network to the SHDSL module for transmission over the loop.

The Octal SHDSL module occupies one slot in the Total Access DSLAM shelf allowing 176 subscribers per single 48.26 cm chassis (224 for 58.42 cm chassis). Each SHDSL port is individually configurable and supports rates from 192 kbps to 2.304 Mbps over a single copper pair. The front panel is equipped with an LED for each port to quickly determine circuit status.

Each SHDSL circuit utilizes the Trellis Coded Pulse Amplitude Modulation

(TC PAM) line code scheme ensuring spec- tral compatibility with existing binder group services. ADTRAN’s SHDSL module is 100 percent compliant with the ITU Standard for SHDSL transmission (G.991.2) for interoper- ability with other standards-based SHDSL products.

The Total Access system offers several methods for user-friendly operation, admin- istration, maintenance, and provisioning of the entire SHDSL circuit. SNMP manage- ment using ADTRAN’s Total Access Element Management System (EMS) or other SNMP- based systems is provided via the 10BaseT connection on the Total Access DSLAM shelf.
