About the TDM SHDSL Endpoint
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.
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. Thirty-one line rates are available.
At all rates, a 3 Kbps Embedded Operations Channel (EOC) is available, which
enables functions such as firmware downloads to remote units. Units can also be
configured manually to full or fractional E1 rates.
Hotwire products transport data over a 2-wire, full-duplex circuit over varying
distances based on the conditions of the loop. Using 24 AWG cable, these
TDM SHDSL products have a loop reach greater than 15,000 feet (4.6 km) at
2.048 Mbps.

TDM SHDSL Endpoint Features
Hotwire TDM SHDSL Models 7995/7996 are endpoints for the chassis-mounted
Hotwire 8799 Line Card that is housed in the Hotwire 8600 or 8800 Series Digital
Subscriber Line Access Multiplexer (DSLAM).
Two Hotwire TDM SHDSL endpoints can also be configured to operate in a central
office SHDSL Transceiver Unit, Central Site (STU-C)-to-customer premises
SHDSL Transceiver Unit, Remote Terminal Site (STU-R) environment.
Hotwire TDM SHDSL endpoints have these standard features:

Embedded Operations Channel (EOC). Provides remote management and
download capabilities via an SNMP or Telnet session over the DSL network on
a 3 Kbps channel.

Asynchronous Terminal Interface (ATI). Provides a menu-driven
VT100-compatible terminal interface for configuring and managing the
endpoint locally or remotely by Telnet session.

Local Management (endpoint). Provides local management using a:
—Terminal or equivalent through the COM port of the unit
—Telnet through the COM port of the unit

Remote Management (DSLAM card). Provides remote management using:
—VT100-compatible terminal or PC via the Management Serial port of the
DSLAM
—NMS through the MCC 10BaseT port of the DSLAM
—Telnet over the EOC

Alarm Indication. Provides front panel status LEDs.

Diagnostic Testing. Provides the capability to diagnose device and network
problems and perform digital loopbacks, pattern tests, and self-test.

Device and Performance Monitoring. Provides the capability of tracking and
evaluating the unit’s operation, including health and status, and error-rate
monitoring.

SNMP (Simple Network Management Protocol) Management. Provides
network management via an industry-standard SNMP management system.

Automatic Configuration Capability. 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.

Network Configuration
Figure 1-1, Sample Configurations, shows a network application using a DSLAM
in a central office (CO). In this configuration, a frame relay switch and router are
connected through the endpoint to partner units supporting a host or router and
frame relay encapsulated or unframed data. The figure also shows a
standalone-to-standalone configuration. Supported standalone-to-
standalone configurations are shown in Table 1-1, Supported Standalone
STU-R/STU-C Combinations.

SNMP Management Capabilities
Hotwire Model 7995/7996 endpoints support SNMP Version 1, and can be
managed by any industry-standard SNMP manager and accessed by external
SNMP managers using SNMP.
Management Information Base (MIB) Support
For a detailed description of the supported MIBs, visit Paradyne’s Web site at
www.paradyne.com. Select
Technical Support

MIBs.
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.


Entity MIB (RFC 2037) –Supports all DSLAM cards.

DS1/E1/DS2/E2 MIB (RFC 2495 (was 1406)) –Reports the performance
status of the interface and supports the features found on the Performance
Statistics screen.

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.

Paradyne Enterprise MIB –Supports configuration, status, statistics, and
tests.

SHDSL MIB (draft-ietf-adslmib-hdsl2.txt) –Supports SHDSL.

SNMP Trap Support
The Hotwire Model 7995/7996 Endpoint supports traps as defined in RFC 1215.
Figure 1-6, DSL SNMP Configuration, illustrates a typical DSL SNMP
configuration. Figure 1-7, DSL Local SNMP Configuration, shows a DSL SNMP
configuration where the NMS is connected directly to the endpoint’s
Communications Port. Figure 1-8, Peer IP Address Assignment, shows an
example of an IP addressing scheme.

Using the Asynchronous
Terminal Interface
User Interface Access
You can communicate with the Hotwire TDM SHDSL endpoint with an
asynchronous terminal interface (ATI) using one of the following methods:

Direct connection through the COM port of the endpoint or through the serial
port of the DSLAM management card.

Telnet session through the Embedded Operations Channel (EOC).
NOTE:
Only one terminal interface session can be active at a time, and another user’s
session cannot be forced to end.
Security can limit ATI access several ways. To limit user access or set up login
IDs, refer to Chapter 5,
Security
.
Communication 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

2. Using the Asynchronous Terminal Interface
2-2 May 2002 7990-A2-GB20-00
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, you will see:

A connection refused or connection failed message (if you are
using a Telnet session), or

The IP address of the other user (if you are using the Management Serial
port).
If security is enabled on the unit and you used Telnet to access it directly (you did
not log in through the DSLAM management card), the system prompts you for a
login ID and password.

2. Using the Asynchronous Terminal Interface
7990-A2-GB20-00 May 2002 2-3
After you enter a valid login ID and password, the Main Menu appears. If you enter
an invalid login ID and password after three attempts, the Telnet session closes or
the terminal connection returns to an idle state. Refer to Chapter 5,
Security
.
Entry to all of the TDM SHDSL endpoint’s tasks begins at the Main Menu screen.
The four branches of the Main Menu are as follows:
After selecting an option, what appears on the screens depends on the:

Current configuration –How your unit 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.
