What is the Hotwire DSLAM?
The Hotwiret Digital Subscriber Line Access Multiplexer (DSLAM) is a DSL
platform that houses a Management Communications Controller (MCC) card and
up to 18 DSL cards. These can be 8310 Multiple Virtual Lines (MVLt) cards,
8510 Rate Adaptive Digital Subscriber Line (RADSL) cards, or a combination of
both.
NOTE:
All references to DSL cards refer to both RADSL and MVL cards, unless
specifically noted otherwise.
The DSLAM interoperates with two types of Hotwire Service Nodes
(SNs)/endpoints to deliver applications at high speeds in support of packet
services over a Digital Subscriber Line (DSL) link.
H The 8310 MVL card interoperates with the Hotwire 6310 MVL modem.
H The 8510 DSL card interoperates with the Hotwire 5620 SN.
The DSLAM is a set of central site products that terminate and consolidate packet
data traffic from many customers in a serving area. It then forwards the traffic to
one or more network access provider networks.
High-speed Internet and intranet access is achieved via a bridge from the DSL
links and then concentrated for efficient forwarding to backbone networks. By
enabling very high speeds using DSL technology and concentrating Internet
Protocol (IP) traffic, greater performance is realized.
In addition, the Hotwire DSLAM with an endpoint such as a 6310 MVL modem
and 5620 SN 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 POTS splitters (Hotwire 5020 Central Office
POTS Splitter and Hotwire 5030 or 5038 Customer Premises POTS Splitter)
allow simultaneous voice and data connections over a standard telephone line.
