What Does the Hotwire 5620 RTU Do?
The Hotwirer 5620 RTU (Remote Termination Unit) is a component in the Hotwire
RADSL Access System and interoperates with the Hotwire 8373, 8374, or 8510 DSL
Card in the DSLAM (Digital Subscriber Line Access Multiplexer) system. This system
provides high-speed Internet or corporate LAN access over traditional twisted-pair
copper telephone wiring.
Copper pairs run from the central office (CO) to the customer premises (CP) to create
the local loop. The local loop terminates on the customer premises at the demarcation
point in a punchdown block or network interface device (NID).
Optional POTS Splitter
An optional POTS (plain old telephone service) splitter can be installed to block out the
DSL signal and allow the POTS frequencies to pass through. At the customer
premises, the 5620 RTU and a telephone can function simultaneously over the same
pair of copper wires when either:
H
H
A Hotwire 5030 or 5038 POTS Splitter is installed near the demarcation point for all
telephones on the same POTS line as DSL, or
A Hotwire 5038 Distributed POTS Filter is installed on each telephone on the same
POTS line as DSL.
