Hotwire 5620 RTU Overview
The Hotwire®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).

NOTE:
In this document:
—End-user system is used to represent any host with an Ethernet connection.
—Service provider is used to represent any Internet Service Provider (ISP) or
remote LAN access provider.
DSL Access with a Hotwire 5030 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 Hotwire 5620 RTU and a telephone can function simultaneously over the same pair
of copper wires when a Hotwire 5030 POTS Splitter is installed near the demarcation
point for all telephones on the same POTS line as DSL.
When a Hotwire 5030 POTS splitter is used at both ends of the local loop, wiring is
connected:
 From the demarcation point to the CP POTS splitter, and
 From the demarcation point to the DSL jack.
The Hotwire 5030 POTS Splitter is designed for outdoor or indoor installation.

DSL Access without a POTS Splitter
When the Hotwire 5620 RTU is installed without a POTS splitter, the DSL line is used for
data only and does not provide telephone services.
Phone Filters
For optimum performance, if the wiring for the RTU is also used for voice (POTS), a
phone filter should be installed on each voice line with a phone, modem, fax machine, or
other telecommunications device attached. One Hotwire phone filter can be used with
multiple telecommunications devices (for example, a phone and fax machine can be
supported using a single filter) if a multiple line adapter is used.
