2. Slots and openings in the cabinet are provided for ventilation. To ensure reliable operation of the product and to
protect it from overheating, these slots and openings must not be blocked or covered.
3. Do not allow anything to rest on the power cord and do not locate the product where persons will walk on the power
cord.
4. Do not attempt to install or service this product yourself, as opening or removing covers may expose you to
dangerous high voltage points or other risks. Refer all installation and servicing to qualified service personnel.
5. General purpose cables are provided with this product. Special cables, which may be required by the regulatory
inspection authority for the installation site, are the responsibility of the customer.
6. When installed in the final configuration, the product must comply with the applicable Safety Standards and
regulatory requirements of the country in which it is installed. If necessary, consult with the appropriate regulatory
agencies and inspection authorities to ensure compliance.
7. A rare phenomenon can create a voltage potential between the earth grounds of two or more buildings. If products
installed in separate buildings are interconnected, the voltage potential may cause a hazardous condition.
Consult a qualified electrical consultant to determine whether or not this phenomenon exists and, if necessary,
implement corrective action prior to interconnecting the products.
8. In addition, if the equipment is to be used with telecommunications circuits, take the following precautions:
—Never install telephone wiring during a lightning storm.
—Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
—Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the
network interface.
—Use caution when installing or modifying telephone lines.
—Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote risk of
electric shock from lightning.
—Do not use the telephone to report a gas leak in the vicinity of the leak.

About the Hotwire 8784
Termination Unit
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.
TDM SDSL termination units can transport data at full (1.544 Mbps) or fractional
payload rates over a 4-wire, full-duplex circuit over varying distances based on the
conditions of the 4-wire loop. Examples include support for router, multiplexer and
PBX connections on 24 gauge (.5 mm) cable up to 21,000 feet (6.4 km).
The termination unit is equipped with an automatic configuration capability that
reduces the installation process to a simple plug-and-play procedure. Simply
connect the unit to the line and it automatically configures itself for the maximum
data rate supported by the local loop. The unit can also be configured for fixed line
speeds to achieve maximum distances.

Hotwire 8784 Termination Unit Features
The 2-port Hotwire 8784 TDM SDSL Termination Unit is a circuit board mounted in
a Hotwire 8600 or 8800 Series Digital Subscriber Line Access Multiplexer
(DSLAM) and used to transport signals at high speeds over a twisted-pair
connection.
The Hotwire 8784 TDM SDSL Termination Unit offers 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 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 Management
Communications Card (MCC) 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.
—NMS connection through the 10BaseT port.

Remote Management. Provides remote management:
—Out-of-band, using an external modem through the Management Serial
port of the DSLAM.
—Telnet over the EOC.
—Using SNMP or Telnet through the 10BaseT port or the Internal
Management Channel (IMC).

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.

Network Configuration
Figure 1-1, Sample CO-to-CP Configuration, shows a T1 network application
using a Hotwire 8784 TDM SDSL Termination Unit for access concentration in a
central office (CO). A frame relay switch and a router are connected to partner
units through the termination unit, supporting a T1 host or router and frame relay
encapsulated or unframed data.

SNMP Management Capabilities
The Hotwire 8784 Termination Unit supports SNMP Version 1, and can be
managed by any industry-standard SNMP manager and accessed using SNMP
by external SNMP managers.
Management Information Base (MIB) Support
For a detailed description of supported MIBs, visit Paradyne’s Web site at
www.paradyne.com. The following MIBs are supported:

MIB II (RFC 1213 and RFC 1573) –Defines the general objects for use with a
network management protocol in TCP/IP internets and provides general

Using the Asynchronous
Terminal Interface
User Interface Access
You can communicate with the asynchronous terminal interface (ATI) using one of
the following methods:

Direct connection through the Management Serial port of the DSLAM (locally
or via an external modem).

Telnet session using a Network Management System (NMS) connected to a
LAN/WAN port on the DSLAM.

Telnet session through the Embedded Operations Channel (EOC).
NOTE:
Only one ATI session can be active at a time, and another user’s session
cannot be forced to end. To automatically log out a user due to inactivity,
enable the Inactivity Timeout option (see Table A-5, Telnet Session Options, in
Appendix A,
Configuration Options
.
Security can limit ATI access several ways. To set up security or a login ID, refer to
Chapter 7,
Security.
Management Serial Port Settings
Ensure that the device you connect communicates using these settings:

Data rate set to 9.6 kbps.

Character length set to 8.

Parity set to None.

Stop Bits set to 1.
Refer to the installation document for your DSLAM.

2. Using the Asynchronous Terminal Interface

Logging In to the Hotwire DSLAM
You can log in to the Hotwire DSLAM system using either a local
VT100-compatible terminal or a remote Telnet connection.
After you enter your user ID and password, the system displays the Hotwire
Chassis Main Menu. See your Management Communications Controller (MCC)
documentation for information about selecting the unit from the MCC card
selection screen.
Initiating an ATI Session
The Main Menu screen is displayed unless a login ID and password is required or
the ATI is already in use.
If the ATI is already in use, the message connection refused is sent to the
terminal attempting Telnet access.
If security is enabled and Telnet is used to access the terminal unit directly (you did
not log in through the MCC), the system prompts you for a login ID and password.
If you enter an invalid login ID and password three times, the Telnet session closes
or the terminal connection returns to an idle state. Refer to Chapter 7,
Security
.
