Model 3810 or Model 3820 Modem Installation
The following procedures describe how to connect the standalone modem to the dial line, leased
line, and ac power transformer.
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 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.
