Installation Instructions

Document Number 5620-A2-GN10-30 December 1998

Before You Begin

The Hotwire 5620 RTU (Remote Termination Unit) interoperates with the Hotwire 8510 DSL Card in the DSLAM (Digital Subscriber Line Access Multiplexer) system.

An optional POTS (Plain Old Telephone Service) splitter is available for the Hotwire 5620 RTU. When a POTS splitter is installed, the telephone and 5620 RADSL (Rate Adaptive Digital Subscriber Line) RTU can function at the same time over the same pair of copper wires. In order to confirm the RTU installation, the POTS splitter should be installed first.

To install a POTS splitter, refer to the appropriate POTS splitter document:

What Does the Hotwire RADSL 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:

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

telephones on the same POTS line as DSL,

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

POTS line as DSL.

DSL Access with a Hotwire 5030 or 5038 POTS Splitter

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:

H From the demarcation point to the CP POTS splitter, and H From the demarcation point to the DSL jack.

Installing the DSL Access Wiring

The local loop terminates at the punchdown block or NID. Wiring must be connected from the customer premises side of the punchdown block or the NID to the DSL jack. Typically, the punchdown block is installed in commercial locations and the NID is installed in residential locations.

 Procedure

1. Access the punchdown block or NID.

WARNING:

Do not continue unless the DSL access line from the local loop has been disconnected at the NID or punchdown block. Refer to

Instructions,

2. Disconnect the DSL access pair from the local loop. A punchdown block is used

without a POTS splitter in the following example.
