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
1-2 May 2002 8700-A2-GB20-40
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.
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 Telnet 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 remotely by Telnet session.

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 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 T1 network application
using a Hotwire 8777 or 8779 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 2863 (was 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.

DS1/E1 MIB (RFC 2495 (was 1406)) –Reports the performance status of the
DSX-1 or G.703 interface and supports the features found on the DSX-1 or
G.703 Performance Statistics screen.

Entity MIB (RFC 2037) –Supports all DSLAM cards.

Enterprise MIBs –Supports configuration, status, statistics, and tests.
SNMP Trap Support
The Hotwire 8777 or 8779 TDM SDSL Termination Unit supports SNMP traps as
shown in Appendix B,
Standards Compliance for SNMP Traps
.

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 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,
Configuration Options
).
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
Product-Related
Documents
in
About This Guide
.

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 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.
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 6,
Security
.
If the ATI is already in use, the message connection refused is sent to a
terminal attempting Telnet access.
