3800 Series Modem Package

After opening the modem's package, check for damage and verify that the following items are
present:
For the standalone models
For the carrier-mounted model
If any hardware components are damaged, notify your sales representative.

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.
Figure 2-1 and Figure 2-2 show how Model 3810 and Model 3820 modems are connected to
certain TELCO jack types using the supplied cables.
