About the Hotwire 7984
Standalone Termination Unit 1
M/HDSL Overview
HotwiretMultirate High-bit-rate Digital Subscriber Line (M/HDSL) 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 can transport at full (2.048 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).
Hotwire M/HDSL is equipped with an automatic configuration capability that
reduces the M/HDSL 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. M/HDSL units can also be
configured at fixed line speeds to achieve maximum distances.
Hotwire 7984 Termination Unit Features
The Hotwire 7984 M/HDSL Standalone Termination Unit is an endpoint for the
chassis-mounted Hotwire 8784 M/HDSL Termination Unit housed in the Hotwire
8600 or 8800 Digital Subscriber Line Access Multiplexer (DSLAM).
Two Hotwire 7984 M/HDSL Standalone Termination Units can also be configured
to operate in a central office LTU to customer premises NTU environment.
The 7984 Standalone Termination Unit offers these standard features:
HEmbedded Operations Channel (EOC). Provides remote SNMP Traps,
Telnet session capability over the M/HDSL link, and download capabilities.
HAsynchronous Terminal Interface (ATI). Provides a menu-driven

SNMP Management Capabilities
The 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
http://www.paradyne.com. The following MIBs are supported:
HMIB II (RFC 1213 and RFC 1573) – Defines the general objects for use with
a network management protocol in TCP/IP internets and provides general
information about the unit. MIB II is backward-compatible with MIB I.
HDS1 MIB (RFC 1406) – Reports the performance status of the DSX-1
interface and supports the features found on the DSX-1 Performance
Statistics screen.
HRS-232-Like MIB (RFC 1659) – Defines objects for managing RS-232-type
interfaces (e.g., V.35, RS-422, RS-423, etc.) and supports the synchronous
data port on the DSU.
HEnterprise MIB – Supports configuration, status, statistics, and tests.
SNMP Trap Support
The 7984 Standalone Termination Unit supports traps as defined in RFC 1215.
Figure 1-4 illustrates a typical M/HDSL SNMP configuration. Refer to Chapter 8,
IP Addressing and Appendix B, Standards Compliance for SNMP Traps .

Using the Asynchronous Terminal
Interface 2
User Interface Access
You can communicate with the Hotwire 7984 Standalone Termination Unit with an
asynchronous terminal interface (ATI) using one of the following methods:
HDirect connection through the COM port of the standalone unit or through the
serial port of the DSLAM MCC.
HTelnet session through the Embedded Operations Channel (EOC).
NOTE:
Only one terminal interface 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 Option Tables ).
Security can limit ATI access several ways. To limit user access or set up login
IDs, refer to Chapter 7,
Security .
Communication Port Settings
Ensure that the device you connect communicates using these settings:
HData rate set to 9.6 kbps.
HCharacter length set to 8.
HParity set to None.
HStop Bits set to 1.

Using the Asynchronous Terminal Interface
2-2 7984-A2-GB20-10

Initiating an ATI Session
The Main Menu screen is displayed on the screen unless a login ID and
password is required or the ATI is already in use.
If the ATI is already in use, you will see a connection refused or
connection failed message (if you are using a Telnet session), or you will
see the IP address of the other user (if you are using the Management Serial
port).
If security is enabled on the 7984 Standalone Termination Unit and you used
Telnet to access it directly (you did not log in through the MCC), the system
prompts you for a login ID and password.
