About the Hotwire Standalone

Termination Unit

1

M/SDSL Overview

Hotwirer Multirate Symmetric Digital Subscriber Line (M/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 products support autorate. Units first synchronize to the highest line rate

that the 2-wire loop supports, and then automatically configure to the highest

multiple of 64 kbps supported by that line rate. Eight line rates are available. At all

rates, a 16 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.

Hotwire products transport data over a 2-wire (M/SDSL) full-duplex circuit over

varying distances based on the conditions of the loop. Using 24 AWG cable,

M/SDSL products have a loop reach greater than 14,000 feet (4.6 km) at

2.048 Mbps.

Hotwire Standalone Termination Unit Features

The Hotwire Standalone Termination Unit is an endpoint for the chassis-mounted

Hotwire 877x Termination Unit housed in the Hotwire 8600 Series or 8800 Series

Digital Subscriber Line Access Multiplexer (DSLAM).

Two Hotwire Standalone Termination Units can also be configured to operate in a

central office line termination unit (LTU) to customer premises network

termination unit (NTU) environment.

The termination unit offers these standard features:

H Embedded Operations Channel (EOC). Provides remote SNMP Traps,

Telnet session capability over the M/SDSL link, and download capabilities.

H Asynchronous Terminal Interface (ATI). Provides a menu-driven

VT100-compatible terminal interface for configuring and managing the

termination unit locally or remotely by Telnet session.

H Local Management (standalone unit). Provides local management using a:

— Terminal or equivalent through the COM port of the unit

— Telnet through the COM port of the unit

Network Configuration

Figure 1-1 shows a network application using a termination unit in a central office

(CO). In this configuration, a frame relay switch and a router are connected

through the termination unit 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.

SNMP Management Capabilities

The Hotwire 797x Standalone Termination Units support 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 the supported MIBs, visit Paradyne’s Web site at

www.paradyne.com. Select Technical Support → MIBs.

The following MIBs are supported:

H 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.

H DS1/E1 MIB (RFC 1406) – Models 7974 and 7976. 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.

H 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.

H Paradyne Enterprise MIB – Supports configuration, status, statistics, and

tests.

SNMP Trap Support

Hotwire 797x Standalone Termination Units support traps as defined in

RFC 1215.

Figure 1-8 illustrates a typical DSL SNMP configuration. Figure 1-9 illustrates an

DSL SNMP configuration connected directly to the Communications Port. Refer

to Chapter 5, IP Addressing and Appendix B, Standards Compliance for SNMP

Traps.

Using the Asynchronous Terminal

Interface

2

User Interface Access

You can communicate with the Hotwire Standalone Termination Unit with an

asynchronous terminal interface (ATI) using one of the following methods:

H Direct connection through the COM port of the standalone unit or through the

serial port of the DSLAM management card.

H 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. To automatically log out a user due to

inactivity, enable the Inactivity Timeout option (see Table A-9, Telnet Session

Options, in Appendix A, Configuration Options).

Security can limit ATI access several ways. To limit user access or set up login

IDs, refer to Chapter 6, Security.

Communication Port Settings

Ensure that the device you connect communicates using these settings:

H Data rate set to 9.6 kbps.

H Character length set to 8.

H Parity set to None.

H Stop Bits set to 1.

7900-A2-GB21-00

Initiating an ATI Session

The Main Menu screen is displayed on the screen 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:

H A connection refused or connection failed message (if you are

using a Telnet session), or

H 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.
