About the Hotwire 8799 Line Card
TDM SHDSL Overview
Hotwire®Time Division Multiplexer Symmetric High-bit-rate Digital Subscriber Line
(TDM SHDSL) 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.
TDM SHDSL line cards can transport data at full (2.048 Mbps) 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 up to 15,000 feet (4.6 km).
The line card is equipped with an automatic configuration capability that reduces
the installation process to a simple plug-and-play procedure. Simply connect the
card to the line and it automatically configures itself for the maximum data rate
supported by the local loop. The card can also be configured for fixed line speeds
to achieve maximum distances.

1-2 April 2003 8799-A2-GB20-10
Hotwire 8799 Line Card Features
The 8-port Hotwire 8799 TDM SHDSL Line Card is a circuit board mounted in a
Hotwire 8610/8620 or 8810/8820 Digital Subscriber Line Access Multiplexer
(DSLAM) and used to transport signals at high speeds over a twisted-pair
connection.
The Hotwire 8799 TDM SHDSL Line Card offers 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 DSL network. The bandwidth of
the EOC is a 3 Kbps dedicated channel.
 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 Management
Communications Card (MCC) 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 line 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.
— Using SNMP or Telnet through the 10BaseT port of the MCC or the
Internal Management Channel (IMC).
 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 card’s operation, including health and status, and error-rate
monitoring. A full suite of loopback tests are supported, which can be initiated
locally or remotely. Performance statistics are also provided.
 DS0 Cross Connection Functionality. Grooms up to eight fractional circuits
onto a single E1 line and allows mapping of separate DS0 ports to specific
voice or data circuits.

Network Configuration
Figure 1-1, Sample STU-C-to-STU-R Configuration, shows an E1 network
application using a Hotwire 8799 TDM SHDSL Line Card for access concentration
in a central office (CO). A frame relay switch and a router are connected to partner
units through the line card, supporting an E1 host or router and frame relay
encapsulated or unframed data.

1. About the Hotwire 8799 Line Card
1-6 April 2003 8799-A2-GB20-10
SNMP Management Capabilities
The line card 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
G.703 interface and supports the features found on the G.703 Performance
Statistics screen.
 Entity MIB (RFC 2037) – Supports all DSLAM cards.
 Enterprise MIBs – Supports configuration, status, statistics, and tests.
 SHDSL MIB (draft-ietf-adslmib-hdsl2.txt) – Supports SHDSL configuration,
status, statistics, and tests.
SNMP Trap Support
The Hotwire 8799 Line Card supports traps as defined in RFC 1215. They may
include variable-bindings specified in the following MIBs:
 MIB II (RFC 2863) – Defines the general objects for use with a network
management protocol in TCP/IP internets and provides general information
about the 8799 line card. MIB II is backward-compatible with MIB I.
 Enterprise MIBs – 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 to each line card, and another
user’s session cannot be forced to end.
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
 Flow Control to None
Refer to the installation document for your DSLAM. See
Product-Related
Documents
in About This Guide .

ATI Access Levels
The card has two access levels: Administrator and Operator on the Hotwire DSL
system. The access level determines what functions are accessible, as shown in
Table 2-1, Access Levels.
The default access is no login and password with Administrator status. To provide
login security to the DSL system, user accounts must be configured.
NOTE:
There must be at least one Administrator configured in order to have system
security.
For information on configuring user accounts, see the
Hotwire Management
Communications Controller (MCC) Card, IP Conservative, User’s Guide.

After you enter a valid login ID and password, the Main Menu appears.
Entry to all of the line card’s tasks begins at the Main Menu screen. The four
branches of the Main Menu are as follows:
What appears on the screens depends on the:
 Current configuration – How your card is currently configured.
 Effective security access level – An access level that is typically set by the
system administrator for each interface and each user.
 Data selection criteria – What you entered in previous screens.
