About Hotwire 8775 and 8785

Termination Units

TDM SDSL Overview

Hotwire®Time Division Multiplexer Symmetric Digital Subscriber Line (TDM

SDSL) 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 TDM SDSL products support router, multiplexer and PBX connections

with maximum loop reaches, as shown in Table 1-1, Maximum Loop Reach.

Hotwire 8775 and 8785 Termination Units are equipped with an automatic

configuration capability that reduces the installation process to a simple

plug-and-play mode. 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.

1. About Hotwire 8775 and 8785 Termination Units

1-2 February 2001 8700-A2-GB25-10

Hotwire 8775 and 8785 Termination Unit Features

A 4-port Hotwire 8775 or 8785 TDM SDSL Termination Unit is a circuit board

mounted in a Hotwire 8600 or 8800 Series Digital Subscriber Line Access

Multiplexer (DSLAM). It is used to transport signals at high speeds over a

twisted-pair connection.

Hotwire 8775 and 8785 Termination Units offer these standard features:



AutoRate Capability. Provides automatic configuration of line speed and data

rate upon connection.



Embedded Operations Channel (EOC). Provides remote management via

SNMP or Telnet session capability over the TDM SDSL network.



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

VT100-compatible terminal interface for configuring and managing the unit

locally or remotely by Telnet session.



Local Management. Provides local management using the DSLAM's

management card with a:

—Terminal or PC via the Management Serial port of the DSLAM.

—Network Management System (NMS) via the Management MCC port of

the 8600 Series DSLAM or 10BaseT port of the 8800 Series DSLAM.



Remote Management. Provides remote management:

—Out-of-band, using an external modem through the Management Serial

port of the DSLAM.

—Using SNMP or Telnet through the 10BaseT port or the Internal

Management Channel (IMC).

—Via Telnet over the EOC.



Alarm Indication. Activates front panel LEDs.



Diagnostics. Provides the capability to diagnose device and network

problems and perform tests, including digital loopbacks, pattern tests, and

self-test.



Device and Test Monitoring. Provides the capability of tracking and

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

monitoring.
