About the Hotwire 7975
Standalone Termination Unit
M/SDSL Overview
Hotwire Multirate/Symmetrical Digital Subscriber Line (M/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 M/SDSL products can transport at full or fractional payload rates over a
2-wire, full-duplex circuit over varying distances based on the conditions of the
2-wire loop. Examples include support for router, multiplexer and PBX
connections at 128 kbps, with distances exceeding 29,000 feet (8.9 km) on
24 gauge (.5 mm) cable, or up to 15,000 feet (4.6 km) delivered at 2.048 Mbps on
24 gauge (.5 mm) cable.
1
Hotwire M/SDSL is equipped with an automatic configuration capability that
reduces the M/SDSL 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/SDSL units can also be
configured at fixed line speeds to achieve maximum distances.

— NMS connection through the 10BaseT port
— Terminal or PC via the Management Serial port of the DSLAM
— Network Management System (NMS) via the COM port or MCC port of
the DSLAM
— Telnet over the EOC
— External modem out-of-band
— Using SNMP or Telnet through the 10BaseT port or the Internal
Management Channel (IMC).
HAlarm Indication. Provides front panel status LEDs.
HDiagnostic Testing. Provides the capability to diagnose device and network
problems and perform tests, including digital loopbacks, pattern tests, and
self-test.
HDevice and Performance Monitoring. Provides the capability of tracking
and evaluating the unit’s operation, including health and status, and error-rate

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.
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.
About the Hotwire 7975 Standalone Termination Unit
SNMP Traps Support
Router
The 7975 Standalone Termination Unit supports traps as defined in
RFC 1215. They may include variable-bindings specified in the following MIBs:
HMIB II (RFC 1573) – Defines the general objects for use with a network
management protocol in TCP/IP internets and provides general information
about the 7975 Standalone Termination Unit. MIB II is backward-compatible
with MIB I.
HEnterprise MIB – Supports configuration, status, statistics, and tests.

Using the Asynchronous Terminal
Interface
User Interface Access
You can communicate with the Hotwire 7975 Standalone Termination Unit with an
asynchronous terminal interface (ATI) using one of the following methods:
HDirect connection through the COM port.
HUsing an external modem through the COM port.
HTelnet session through the Embedded Operations Channel (EOC).
2
NOTE:
Only one asynchronous 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 Sessions Options, in Appendix A,
Security can limit ATI access several ways. To limit user access or set up login
IDs, refer toChapter 7,
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.

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 security is enabled on the 7975 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.

If your package includes a power pack:
Plug the power pack into an ac outlet
having a nominal voltage rating between 100–240 Vac. Connect the output cable
of the power pack to the connector marked POWER on the rear panel.
If your package includes a direct-connection dc power cable:
an external dc power source as described in
External DC Power Source
.
Connecting the Unit to an Optional
Connecting the Unit to an Optional External DC Power Source
Use the following procedures only if you want to use the dc power cable.
Using the dc power cable, the Hotwire 7975 Standalone Termination Unit is
capable of operating on a +24 Vdc power supply.

Connecting to the Network
" Procedure
To connect your unit to the network:
1. Connect one end of the network cable into the rear panel DSL jack. Connect
the other end to your DSL network interface.
NOTE:
Do
not
use a flat VF network cable as this may severely degrade the
performance of the termination unit. Use only Cat 5 twisted-pair network
cable.
Connecting to a System Terminal
An optional system maintenance terminal may be attached to your Hotwire 7975
Standalone Termination Unit through the modular jack on the rear panel. You may
