About the Hotwire 8747, 8777, and 8779 Termination Units

M/SDSL and HDSL2 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 M/SDSL products transmit data over 14,000 feet (4.6 km) at rates up to 2.048 Mbps.

Hotwire High-bit-rate DSL second generation (HDSL2) products transmit data up to 12,000 feet (3.9 km) at up to 1.544 Mbps.

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 87xx 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 supported MIBs, visit Paradyne’s Web site at www.paradyne.com. 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) – 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 Paradyne Enterprise MIB – Supports configuration, status, statistics, and

tests.

SNMP Trap Support

The Hotwire 87xx 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:

H Direct connection through the Management Serial port of the DSLAM (locally

or via an external modem).

H Telnet session using a Network Management System (NMS) connected to a

LAN/WAN port on the DSLAM.

H 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-11,

Telnet Session Options, in Appendix A, Configuration Options).

Security can limit ATI access 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:

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.

8700-A2-GB20-00

Refer to the installation document for your DSLAM.

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 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 on the screen unless a login ID and password is required or the ATI is already in use.

If security is enabled on the Hotwire Termination Unit and you used Telnet to access it directly (you did not log in through the management card), the system prompts you for a login ID and password.

Enter Password:

–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– Ctrl-a to access these functions E

Model: 87xx

xit

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 6, Security.

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