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:
H The Hotwire 8303 or 8304 IP 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
H The 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
H The 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.
