Plus Modem Installation - Paradyne 3800Plus Installation Instructions

3820 Plus Modem Installation

Before installing your modem, make sure your
installation site is clean and well-ventilated. Allow space
around the modem for installing cables and telephone
cords, and make sure the modem is located within reach
of the ac power outlet. The distance between your modem
and the DTE should be minimized if DTE data rates
exceed 19,200 bps. Also, low capacitance cables may be
necessary for speeds greater than 19,200 bps or distances
greater than 50 feet.
The rear panel of the 3820Plus modem has the
following switches and connectors (see Figure 2):
