Overview
This chapter provides installation procedures for the Model 3810, 3820, and 3811 modems
installed in Japan.
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
•Manual and Quick Reference
•Model 3810 or Model 3820 modem
•Power transformer
•One 6-position, 4-wire modular cord (Model 3810 and Model 3820)
•One 8-position to 6-position crossover modular cord (Model 3810 only)
For the carrier-mounted model
•Manual and Quick Reference
•Model 3811 modem
•Rear connector plate with two DB-25-P edge card connectors

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.

Model 3810 and Model 3820 Dial-Line Connection
Use the following procedure to connect the modem to the dial network interface:
1. Insert the 6-position, 4-conductor modular plug into the jack labeled DIAL/LEASED
(3820). See Figure 2-1.
2. Insert the other end of the modular cord into the dial network interface.
Model 3810 4-Wire/2-Wire Leased-Line Connection
Use the following procedure to connect a Model 3810 to the leased-line network interface:
1. Insert the 8-position modular plug into the jack labeled PHONE/LEASED (3810). See
Figure 2-1.
2. Insert the 6-position modular plug into the leased-line network interface.
3. If the Model 3810 has a dial backup line, follow the steps listed in the Model 3810 and
Model 3820 Dial-Line Connection section.
Model 3820 2-Wire Leased-Line Connection
Use the following procedure to connect a Model 3820 modem to the 6-pin, center pair, leased-line
network interface:

Model 3810 and Model 3820 DTE Connection
Use the following procedure to connect the modem to a DTE:
1. Make sure the modem’s rear panel power switch is Off.
2. Connect the DB-25 plug on the cable to the DB-25 socket labeled DTE on the modem’s
rear panel. Use a small screwdriver to fasten the cable to the modem.
3. Connect the other end of the cable to the DTE.
To ensure compliance with FCC Part 15 Regulations, a ferrite choke must be installed on the
EIA-232-D interface cable. See Figure 2-3.
1. Open the ferrite choke and place it around the DTE cable as close as possible to the
connector attached to the modem.
2. Close the two halves around the cable and snap the ferrite choke shut, pressing down on the
plastic latch to secure it.
3. Install a cable tie behind the ferrite choke to prevent it from sliding along the cable.
