ADTRAN Total Access 238 Quick Start Manual

Total Access 238
Octal SHDSL
Bridge
P/N: 1200630L1
CLEI: VAMF400A_ _
DESCRIPTION
The Total Access ® 238 (P/N 1200630L1) is DC-powered, network terminating unit that uses enhanced
Symmetric High-Bitrate Digital Subscriber Line (eSHDSL) technology to transport up to 5.696 Mbps
of data per loop on up to eight copper loops. An AC version (P/N 1200630L2) is also available.
The Total Access 238 interfaces between the incoming IMA-bonded ITU G.991.2 (SHDSL) service
and the customer 10/100Base-T network, for LAN-to-LAN bridging. It can be deployed in pairs (back-
to-back) for a local campus application, or to a DSLAM Line Terminating Unit (LTU) located in a
Central Office (CO) for traditional data service applications. The Total Access 238 can be locally or
remotely provisioned. Local provisioning is accomplished through the V.28 craft interface (DB-9)
using a dumb terminal or PC with terminal emulation software. Remote provisioning is accomplished
using the Embedded Operations Channel (EOC) or the Command Line Interface (CLI), and can initiate
and respond to local and remote loopbacks on the network interfaces.
INSTALLATION
After unpacking the unit, inspect it for damage. If damage is noted, file a claim with the carrier and
then contact ADTRAN. For more information, refer to the warranty.
Mounting Options
The Total Access 238 is a 1U high, rack mountable unit which can be installed in either a 19-inch or
23-inch equipment rack, or in a wallmount configuration. Mounting Brackets and screws are provided
with the unit. For complete mounting instructions, refer to the Installation and Maintenance Practice.
Cables Required
♦
Ethernet cable
♦
SHDSL connection (through the 50-pin amphenol)
Connections
The Total Access 238 is a locally powered standalone unit. It provides a single DC power connector,
eight ITU G.991.2 (SHDSL) single-pair interfaces through a 50-pin amphenol connector, two IEEE
802.3 (10/100Base-T) interfaces through RJ-45 connectors, and one V.28 control port through a DB-9
connector.
Powering
Power to the Total Access 238 must be derived from a grounded –48 VDC nominal (–42 VDC to
–54 VDC) power source. Power connection is made on the two-conductor terminal on the rear panel.
The terminal is removable for easy access to the screws.
Grounding
CAUTION: The grounding conductor must be of equal or greater size than the ungrounded branch-
circuit supply conductor.

FRONT PANEL LEDS
Front panel mounted LEDs provide status information for each SHDSL loop, IMA operation, and
alarms. Ethernet activity LEDs, located on the Ethernet RJ-45 connectors, provide link status and
traffic indications.
