About Hotwire 8775 and 8785
Termination 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 TDM SDSL products support router, multiplexer and PBX connections
with maximum loop reaches, as shown in Table 1-1, Maximum Loop Reach.
Hotwire 8775 and 8785 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.

Hotwire 8775 and 8785 Termination Unit Features
A 4-port Hotwire 8775 or 8785 TDM SDSL Termination Unit is a circuit board
mounted in a Hotwire 8600 or 8800 Series Digital Subscriber Line Access
Multiplexer (DSLAM). It is used to transport signals at high speeds over a
twisted-pair connection.
Hotwire 8775 and 8785 Termination Units offer 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 TDM 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 DSLAM's
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 8600 Series DSLAM or 10BaseT port of the 8800 Series DSLAM.

Remote Management. Provides remote management:
—Out-of-band, using an external modem through the Management Serial
port of the DSLAM.
—Using SNMP or Telnet through the 10BaseT port or the Internal
Management Channel (IMC).
—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.

Network Configuration
Figure 1-1, Sample CO-to-CP Configuration, shows a network application using a
Hotwire 8775 or 8785 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 host or router and frame relay encapsulated or
unframed data.

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
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
information about the unit. MIB II is backward-compatible with MIB I.

RS-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.

Enterprise MIB –Supports configuration, status, statistics, and tests.
SNMP Trap Support
The unit supports traps as defined in RFC 1215. They may include
variable-bindings specified in the following MIBs:

MIB II (RFC 1573) –Defines the general objects for use with a network
management protocol in TCP/IP internets and provides general information
about the termination unit. MIB II is backward-compatible with MIB I.

Enterprise MIB –Supports configuration, status, statistics, and tests.

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. To enable the Inactivity Timeout option,
refer to 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
2-2 February 2001 8700-A2-GB25-10
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 card documentation for information
about selecting the unit from the 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 a
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
.
