2- TO 4-WIRE HYBRID CONVERTER

2. Introduction

With the 2- to 4-Wire Converter, you can use a 2-wire modem on a 4-wire leased
telephone line. It’s a passive device that enables conversion of 2-wire analog
modems for use on 4-wire 600-ohm leased lines. The Converter connects to the
modem and the line via your choice of RJ-11 or screw-terminal connectors. You can
also mix RJ-11 and screw-terminal connections, if necessary. Both the 2-wire and
4-wire connections are insensitive to polarity. Since the Converter receives power
from the attached device, it requires no external power supply.

NOTE

The Converter is designed to operate with 600-ohm VF leased lines only.
It’s not intended for use on dial-up lines.
