About the Hotwire 7975

Standalone Termination Unit

M/SDSL Overview

Hotwire Multirate/Symmetrical 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 can transport at full 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 at 128 kbps, with distances exceeding 29,000 feet (8.9 km) on

24 gauge (.5 mm) cable, or up to 15,000 feet (4.6 km) delivered at 2.048 Mbps on 24 gauge (.5 mm) cable.

Hotwire M/SDSL is equipped with an automatic configuration capability that reduces the M/SDSL installation process to a simple plug and play mode. Simply connecting the units to the line automatically configures the customer for the maximum data rate supported by the local loop. M/SDSL units can also be configured at fixed line speeds to achieve maximum distances.

SNMP Management Capabilities

The termination unit 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

http://www.paradyne.com. The following MIBs are supported:

HMIB 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.

HRS-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.

HEnterprise MIB ± Supports configuration, status, statistics, and tests.
