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 the central site and at the end-user site.

The Hotwire DSL routers interoperate with the following types of Hotwire IP DSL cards (at the DSLAM/GranDSLAM chassis) to deliver applications at high speeds in support of packet services over a DSL link:

HThe Hotwire 8303 or 8304 IP IDSL Cards interoperate with two Hotwire IDSL Routers:

ÐHotwire 6301 IDSL Router with one Ethernet port

ÐHotwire 6302 IDSL Router with a 4-port Ethernet hub

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

ÐHotwire 6341 SDSL Router with one Ethernet port

ÐHotwire 6342 SDSL Router with a 4-port Ethernet hub

HThe Hotwire 8510, 8373, and 8374 IP 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.
