About Hotwire 8777 and 8779
TDM SDSL 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 2-wire TDM SDSL products
transmit data over 14,000 feet (4.6 km) at rates up to 2.048 Mbps.
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. Eight line rates are available. At all
rates, an 8 Kbps management channel is available, which enables functions such
as firmware downloads to remote units. Units can also be configured manually to
full or fractional T1 or E1 rates.

1. About Hotwire 8777 and 8779 TDM SDSL Units
1-2 May 2002 8700-A2-GB20-40
TDM SDSL Features
The 2-wire Hotwire 8777 or 8779 TDM SDSL Termination Unit is a circuit board
that is mounted in a Hotwire 8610 or 8810 Digital Subscriber Line Access
Multiplexer (DSLAM), or an 8620 or 8820 GranDSLAM, and used to transport
signals at high speeds over a twisted-pair connection.
Hotwire 8777 and 8779 TDM SDSL Termination Units have these standard
features:

Cross-Connection Capability. Any DSL port and time slot can be connected
to any DTE port and time slot.

Embedded Operations Channel (EOC). Provides remote management via
SNMP or Telnet session capability over the DSL network. The bandwidth of
the EOC is a 4 Kbps dedicated channel for the Model 8777 and 8 Kbps for the
Model 8779.

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
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 DSLAM through the port card’s 10BaseT port

Remote Management. Provides remote management:
—Out-of-band, using an external modem through the Management Serial
port of the DSLAM
—Inband using one of the DS0 channels as the management channel to
transport SNMP traffic to the MCC card (Model 8779 only).
—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.
