Hotwire DSL System Description
What is the Hotwire DSL System?
The Hotwire
®
Digital Subscriber Line (DSL) system is a set of central site products
that terminate and consolidate packet data traffic from many customers in a
serving area. The DSL card(s) then forwards the traffic to one or more network
access provider networks.
High-speed Internet and intranet access is either bridged or routed on the DSL line
cards and multiplexed over backbone networks. By enabling very high speeds
using DSL technology and concentrating Internet Protocol (IP) traffic, greater
performance is realized.
In addition, the Hotwire GranDSLAM, with an endpoint such as a Hotwire 6310
ReachDSL version 1 (formerly MVL
®
) modem or Hotwire 5620 Remote
Termination Unit (RTU), can co-exist with plain old telephone service (POTS) over
the same copper telephone line, providing simultaneous usage of POTS and
digital applications. That is, the optional central office (CO) POTS splitter and
customer premises POTS filter allow simultaneous voice and data connections
over a standard telephone line.
