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.
