About the Hotwire 79xx
Standalone Termination Unit
M/SDSL and M/HDSL Overview
Hotwire Multirate Symmetric Digital Subscriber Line (M/SDSL) and Multirate
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 M/SDSL products can transport data 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 on 24 gauge (.5 mm) cable at greater than 14,000 feet (4.6 km)
delivered at up to 2.048 Mbps (depending on model).
1
Hotwire M/HDSL products can transport at full 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) delivered at
up to 2.048 Mbps (depending on model).
Hotwire 79xx Standalone Termination Units are equipped with an automatic
configuration capability that reduces the 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. Units can also
be configured at fixed line speeds to achieve maximum distances.

Remote Network Send Line Loopback
The local unit initiates this test by sending a line loopback Up or Down command
to the remote unit for 10 seconds. When the remote unit detects the loopback Up
command, it puts itself in line loopback and lights the front panel test LED. The
remote unit remains in loopback until it receives a loopback Down command or
the remote unit’s test timeout value is exceeded. The send line loopback tests
both units. External equipment can be used to verify the link.

Overview

The Hotwire 79xx Standalone Termination Unit provides several methods of
security by limiting user access to the ATI through option settings. You can:
H Enable the Telnet Login Required option.
H Limit the access by setting a Session Access Level option of Operator for the
Telnet Session.
H Disable the access with the Telnet Session option.
See Table A-7, Telnet Session Options, in Appendix A,

ATI Access Levels
The Hotwire 79xx Standalone Termination Unit has two access levels:
Administrator and Operator. The access level determines what functions are
accessible, as shown in Table 8-1.
Table 8-1. Access Levels
ATI Access to Menu Functions Administrator Operator
Status Read-Only Read-Only
Test Full Access No Access
Configuration Full Access Read-Only
Control Full Access No Access
Access levels can be applied to Login IDs, the COM port, and Telnet sessions.
The effective access level is always the most restrictive:
H When access is through the COM port and a login is required on the COM
port, the effective access level is the more restrictive of the COM port access
level or the login access level. (See Table A-6, Communication Port Options.)
H When access is through Telnet and a login is required for Telnet, the effective
access level is the more restrictive of the Telnet session access level or the
login access level. (See Table A-7, Telnet Session Options.)
When an access level of Operator is applied to the COM port and to Telnet
sessions, a Login ID with Administrator authority is effectively reduced to
Operator. It is no longer possible to change configuration options, and full access
can be restored only by reloading factory defaults. (See
Port or Factory Defaults
on page 8-6.)
