Installation
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 reference card
•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 reference card
•Model 3811 modem
•Rear connector plate with two DB-25-P edge card connectors
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.

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), 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),
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:
1. Insert the 6-position, 4-conductor modular plug into the jack labeled DIAL/LEASED
(3820), Figure 2-2.
2. Insert the other end of the modular cord into the leased-line network interface.
AC Power Transformer Connection
The 90–110 volt power transformer is equipped with a 5-pin DIN connector for modem
connection, and a grounded line cord for AC power outlet connection.
Use the following procedure to connect the standalone modem to an ac power outlet:
1. Make sure the modem’s power switch is in the Off position.
2. Insert the power transformer’s 5-pin DIN male connector into the modem’s rear panel ac
power receptacle (Figures 2-1 and 2-2).
3. Insert the line cord’s wall plug into the appropriate grounded ac outlet.

Restrictions and Configuration
Options
Overview
This chapter lists restrictions and configuration options that are unique to the operation of 3800
modems installed in Japan. The information described in this chapter differs from what is listed in
the COMSPHERE 3800 Series Modems, Models 3810, 3811, and 3820, User’s Guide.
If a configuration option is not listed in this supplement, your modem’s functionality and operation
follow what is described in the COMSPHERE 3800 Series Modems, Models 3810, 3811, and 3820,
User’s Guide.
Restrictions
Due to JATE (Japan Approvals Institute for Telecommunications Equipment) regulations, only 3
attempts to dial a number are permitted in a 3-minute period. If a fourth attempt is made to dial the
same number, the modem returns the ERROR return code. This restriction applies to number
dialed from the command line or from a directory. An occurrence of the restriction is canceled
when a different number is dialed, or when 3 minutes have elapsed.
The fax feature is not available on modems installed in Japan.
