1. Introduction to Hotwire DSL Routers

Typical DSL Router System

DSL is a local loop technology that uses standard twisted-pair copper wire to support high-speed access over a single pair of twisted copper wires. DSL applications are point-to-point, requiring DSL devices at central and end-user sites.

Hotwire DSL routers interoperate with the following types of Hotwire DSL line cards, at the DSLAM (Digital Subscriber Line Access Multiplexer) or GranDSLAM chassis, to deliver applications at high speeds, supporting packet services over a DSL link:

￿Hotwire 8303 or 8304 IDSL Cards interoperate with two Hotwire IDSL Routers:

—Hotwire 6301 IDSL Router with one Ethernet port

—Hotwire 6302 IDSL Router with a 4-port Ethernet hub

￿Hotwire 8343 or 8344 SDSL Cards interoperate with two Hotwire Symmetric DSL Routers:

—Hotwire 6341 SDSL Router with one Ethernet port

—Hotwire 6342 SDSL Router with a 4-port Ethernet hub

￿Hotwire 8312 or 8314 ReachDSL Cards interoperate with the Hotwire 6351 ReachDSL Router with one Ethernet port

￿Hotwire 8510, 8373, and 8374 RADSL Cards interoperate with the Hotwire 6371 RADSL Router with one Ethernet port

The following illustration shows a typical Hotwire system with a Hotwire DSL Router. All Hotwire DSL routers transport data. The Hotwire 6371 RADSL Router can transport data and POTS simultaneously.
