About the TDM SHDSL Endpoint

TDM SHDSL Overview

Hotwire®Time Division Multiplexer Symmetric High-bit-rate Digital Subscriber Line

(TDM SHDSL) products maximize customer service areas by varying the DSL line

rate. This ensures symmetric DSL connectivity over a wide range of telephone line

distances and transmission line qualities.

Hotwire products support autorate. Units first synchronize to the highest line rate

that the 2-wire loop supports, then automatically configures the unit to the highest

multiple of 64 Kbps supported by that line rate. Thirty-one line rates are available.

At all rates, a 3 Kbps Embedded Operations Channel (EOC) is available, which

enables functions such as firmware downloads to remote units. Units can also be

configured manually to full or fractional E1 rates.

Hotwire products transport data over a 2-wire, full-duplex circuit over varying

distances based on the conditions of the loop. Using 24 AWG cable, these

TDM SHDSL products have a loop reach greater than 15,000 feet (4.6 km) at

2.048 Mbps.

1. About the TDM SHDSL Endpoint

1-2 May 2002 7990-A2-GB20-00

TDM SHDSL Endpoint Features

Hotwire TDM SHDSL Models 7995/7996 are endpoints for the chassis-mounted

Hotwire 8799 Line Card that is housed in the Hotwire 8600 or 8800 Series Digital

Subscriber Line Access Multiplexer (DSLAM).

Two Hotwire TDM SHDSL endpoints can also be configured to operate in a central

office SHDSL Transceiver Unit, Central Site (STU-C)-to-customer premises

SHDSL Transceiver Unit, Remote Terminal Site (STU-R) environment.

Hotwire TDM SHDSL endpoints have these standard features:



Embedded Operations Channel (EOC). Provides remote management and

download capabilities via an SNMP or Telnet session over the DSL network on

a 3 Kbps channel.



Asynchronous Terminal Interface (ATI). Provides a menu-driven

VT100-compatible terminal interface for configuring and managing the

endpoint locally or remotely by Telnet session.



Local Management (endpoint). Provides local management using a:

—Terminal or equivalent through the COM port of the unit

—Telnet through the COM port of the unit



Remote Management (DSLAM card). Provides remote management using:

—VT100-compatible terminal or PC via the Management Serial port of the

DSLAM

—NMS through the MCC 10BaseT port of the DSLAM

—Telnet over the EOC



Alarm Indication. Provides front panel status LEDs.



Diagnostic Testing. Provides the capability to diagnose device and network

problems and perform digital loopbacks, pattern tests, and self-test.



Device and Performance Monitoring. Provides the capability of tracking and

evaluating the unit’s operation, including health and status, and error-rate

monitoring.



SNMP (Simple Network Management Protocol) Management. Provides

network management via an industry-standard SNMP management system.



Automatic Configuration Capability. Simply connecting the units to the line

automatically configures the customer for the maximum data rate supported

by the local loop. Units can also be configured at fixed line speeds to achieve

maximum distances.
