3810 Plus Input Voltage Requirements
The power supply used with the 3810Plus modem (Figure 1) is designed for an input voltage of 240 Vac
( 10 percent), and an input frequency of 50 Hz.

3810 Plus Modem Installation

The following procedures describe how to connect the standalone modem to the leased line, dial line, and power
supply.
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 1 shows how 3810Plus modems are connected to certain TELCO jack types using the supplied cables.
3810 Plus 4-wire/2-wire Leased-Line Connection
Use the following procedure to connect a 3810Plus to the leased-line network interface (use the VF cord labeled

LEASED LINE):

1. Insert the 8-position, 4-conductor modular plug into the jack labeled LEASED (3810Plus), Figure 1.
2. Insert the BT631A-type modular plug into the leased-line network interface.
3810 Plus Dial-Line Connection
Use the following procedure to connect the modem to the dial network interface (use the VF cord labeled
DIAL LINE):
1. Insert the 8-position, 2-conductor modular plug into the jack labeled DIAL, Figure 1.
2. Insert the BT431A-type modular plug into the dial network interface.
