About Hotwire 8777 and 8779 TDM SDSL 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 2-wire TDM SDSL products
transmit data over 14,000 feet (4.6 km) at rates up to 2.048 Mbps.
Hotwire products support autorate. Units first synchronize to the highest line rate
that the 2-wire loop supports, then automatically configures the unit to the highest
multiple of 64 Kbps supported by that line rate. Eight line rates are available. At all
rates, an 8 Kbps management channel is available , which enables functions such
as firmware downloads to remote units. Units can also be configured manually to
full or fractional T1 or E1 rates.

1. About Hotwire 8777 and 8779 TDM SDSL Units
TDM SDSL Features
The 2-wire Hotwire 8777 or 8779 TDM SDSL Termination Unit is a circuit board
that is mounted in a Hotwire 8610 or 8810 Digital Subscriber Line Access
Multiplexer (DSLAM), or an 8620 or 8820 GranDSLAM, and used to transport
signals at high speeds over a twisted-pair connection.
Model . . . Has eight . . . And eight . . .
8777 TDM SDSL ports DSX-1 ports
8779 TDM SDSL ports G.703 ports
Hotwire 8777 and 8779 TDM SDSL Termination Units have these standard
features:
Cross-Connection Capability.
Any DSL port and time slot can be connected
to any DTE port and time slot.
Embedded Operations Channel (EOC).
Provides remote management via
SNMP or Tel net session capability over the DSL network. The bandwidth of
the EOC is a 4 Kbps dedicated channel for the Model 8777 and 8 Kbps for the
Model 8779.
Asynchronous Terminal Interface (ATI).
Provides a menu-driven
VT100-compatible terminal interface for configuring and managing the unit
locally or r e motely by Telnet ses s ion .
Local Management.
Provides local management using the DSLAM
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 DSLAM through the port card’s 10BaseT port
Remote Management.
Provides remote management:
— Out-of-band, using an external modem through the Management Serial
port of the DSLAM
— Inband using one of the DS0 channels as the management channel to
transport SNMP traffic to the MCC card (Model 8779 only).
— Via Teln et over the EOC
Alarm Indicati o n.
Diagnostics.
Activates front panel LEDs.
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.

1. About Hotwire 8777 and 8779 TDM SDSL Units
SNMP Management Capabilities
The termination unit suppor t s SNM P 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:
SNMP Trap Support
MIB II (RFC 1213 and RFC 2863 (was 1573))
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.
DS1/E1 MIB (RFC 2495 (was 1406))
DSX-1 or G.703 interface and supports the features found on the DSX-1 or
G.703 Perform anc e Statistics screen.
Entity MIB (RFC 2037)
Enterprise MIBs
The Hotwire 8777 or 8779 TDM SDSL Termination Unit suppor ts SNM P traps as
shown in Appendix B,
– Suppor ts all DSLAM cards.
– 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).
Tel net session using a Network Manag eme nt System (NMS) connected to a
LAN/WAN port on the DSLAM.
Tel net session through the Embedded Operation s 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-12,
Telnet Session Options, in Appendix A,
Security can limit ATI access in several ways. To set up security or a login ID, refer
to Chapter 6,
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. See

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 T elnet connection.
After you enter yo u r us er ID and pass wo r d, 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 security is enabled on the termination unit and Telnet is used to access the unit
directly (you did not log in through the MCC), the system prompts you for a login
ID and password.

Procedure
To upload or download a configuration:
1. Position the cursor in the Image File Name field. Type the name of the file to
be downloaded, or the name to be used for the file to be uploaded.
The filename may be a regular path name expression of directory names
separated by a forward slash (/) ending with the filename. The total path name
length can be up to 128 characters.
—
DOS machine:
If the TFTP server is hosted by a DOS machine, then
directory and filenames must consist of eight or less characters with an
optional suffix of up to three characters. The system will automatically
upload the configuration file and create directories and filenames, as
needed.
—
UNIX machine:
If your server is hosted by a UNIX machine, the
configuration file you name must already exist. It will not be created on the
UNIX system by the TFTP server. It is critical that you work with your
system administrator to plan the naming conventions for directories,
filenames, and permissions so that anyone using the system has read and
write permissions.
—
MCP FFS:
When uploading configuration files to the MCP FFS, the
directory and filename must be entered, otherwise the download will fail.
