Introduction to the HotWire
DSLAM

What is the HotWire DSLAM?
The HotWire Digital Subscriber Line Access Multiplexer (DSLAM) is a DSL
platform that interoperates with a HotWire 5446 Remote Termination Unit (RTU)
to deliver applications at multimegabit speed in support of packet services over a
Digital Subscriber Line (DSL) link.
High-speed service traffic types from the DSL links are groomed and then
concentrated for efficient forwarding to backbone routers. By enabling very high
speeds using DSL technology and then concentrating Internet Protocol (IP)
traffic, greater performance is realized. Backbone service nodes can be placed
deeper into the network, dramatically improving the economics of service
provisioning while taking advantage of the substantial speed increases of DSL.
In addition, the HotWire DSLAM with the HotWire 5446 RTU can be multiplexed
with Plain Old Telephone Service (POTS) over the same copper line providing
simultaneous usage of POTS and digital application to separate locations. That
is, the optional POTS Splitters (HotWire 5020 Central Office POTS Splitter and
HotWire 5030 Customer Premises POTS Splitter) allow simultaneous voice and
data connections over a standard telephone line.
