Total Access DSLAM Octal SHDSL Access Module
The ADTRAN TM Total Access
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.
® Octal SHDSL 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.
