Introduction to the HotWire
DSLAM
What is the HotWire DSLAM?
8000-A2-GB21-20
The HotWire Digital Subscriber Line Access Multiplexer (DSLAM) is a
multiservices DSL platform that provides high-speed Internet or Intranet access
over traditional twisted-pair telephone wiring. The DSLAM chassis houses DSL
cards that interoperate with multiple types of HotWire Remote Termination Units
(RTU) to deliver applications at multimegabit speeds 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.
When used in combination with a HotWire 8200 Interworking Packet
Concentrator (IPC), the HotWire DSLAM provides high-speed IP service
concentration over a wide array of Local Area Network (LAN) architectures as
well as an Asynchronous Transfer Mode (ATM) interface to Wide Area Networks
(WANs).
In addition, the HotWire DSLAM with a HotWire RTU can be multiplexed with
Plain Old Telephone Service (POTS) over the same copper line providing
simultaneous usage of POTS and digital applications to separate locations. That
is, the optional POTS splitters allow simultaneous voice and data connections
over a standard telephone line.
NOTE:
If you would like more information on DSL-based services, applications, and
network deployment, refer to Paradyne's DSL Sourcebook. The book may be
ordered by calling 1-800-PARADYNE.
