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.

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). Tel net session using a Network Manag eme nt System (NMS) connected to a



LAN/WAN port on the DSLAM. Tel net session through the Embedded Operation s 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,

Security can limit ATI access in several ways. To set up security or a login ID, refer to Chapter 6,

Cross-Connecting Ports

Overview

Configuration of the cross-connections consists of the following steps:

Determine how the ports will be connected and configured.

❑

On the Network Interface Options screen, enable the DSL ports that will be in

❑

the cross-connection if necessary. The ports are enabled by default. On the DSX-1 or G.703 Interface Options screen, enable the DSX-1 or G.703

❑

ports that will be in the cross -c onnect ion. For G.703, specify whether Time Slot 16 is used for signaling (voice mode).

On the System Clock screen, configure the system clock.

❑

On the Cross-Connect Mode screen:

❑

— Define all DS1 Bypass ports. — Define all DS1 Cross-Connect ports. — Define all DS0 Cross-Connect ports.

On the Assign Time Slots screen, configure the DS0 cross-connections.

❑

This chapter describes the use of the Cross-Connect Mode and Assign Time Slots screens. See Appendix A, configuration options presented on the other screens.

Examples in this chapter show screens for DSX-1 models. The principles of cross-connection are the same for G.703 models.

IMPORTANT:

All DSL time slots are available for cross-connect regardless of DSL line rate, but all time slots are available for data transport only if the DSL line rate is the full rate (1552 for DSX-1 or 2064 for G.703). Configure only the time slots intended for use.

— For G.703 ports using Common Channel Signaling (CCS) that are in DS0

Cross-Connect mode, you must explicitly configure the cross-connections for Time Slot 16 and related time slots.

You may find it useful to diagram your configuration. Appendix E,
