What Does the Hotwire 5620 RTU Do?

The Hotwire 5620 RTU is a component in the Hotwire DSL Access System. This

system provides high-speed Internet or corporate LAN access over traditional

twisted-pair copper telephone wiring.

A POTS splitter blocks out the DSL signal and allows the POTS frequencies to pass

through. At the customer premises, the RADSL RTU and a telephone can function

simultaneously over the same pair of copper wires when either:

HA Hotwire 5030 or 5038 POTS Splitter is installed near the demarcation point for all

telephones on the same POTS line as DSL,

HA Hotwire 5038 Distributed POTS Filter is installed on each telephone on the same

POTS line as DSL.

In this document:

— End-user system is used to represent any PC with an Ethernet connection and

DSL-based service.

— Network Service Provider (NSP) is used to represent any Internet Service

Provider (ISP) or remote LAN access provider.

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).

The Hotwire 5030 POTS splitter is designed for outdoor or indoor installation. The

Hotwire 5038 POTS Splitter is designed for indoor use only.

When a Hotwire POTS splitter is used at both ends of the local loop, wiring is

connected:

HFrom the demarcation point to the CP POTS splitter, and

HFrom the demarcation point to the DSL jack.
