Installing a networking modem

Introduction

This section describes the additional hardware and software

installation procedures required to take advantage of

Meridian Mail’s networking capabilities. No additional

hardware installation is required for AMIS or Virtual Node

AMIS.

Note: You must have the Meridian Networking feature

installed. The “Installing Meridian Networking hardware”

chapter in the Network Installation Guide

(NTP 555-7001-213) describes how to configure a port

that was not configured at software installation time.

You will require an analog line card in the Meridian 1 Option

11 switch for the Meridian Networking connection to provide

transmission of control data used in the Meridian Mail

transfer protocol.

Supported modems

The U.S. Robotics 33.6 and 14.4 modems are the only

networking modems supported for the EC 11. Only the

U.S. Robotics 33.6 modem is shipped with new systems.

Installing a

networking modem

To install a networking modem, follow these steps.

Step Action

1 Connect the RS-232 port on the modem to the

RS-232 port on the EC 11 that has been configured

for a networking modem. (This is usually port 3 on

the 4-port fanout cable attached to the 4RS232

connector on Node 1.) If you are using the fanout

cable, plug the configured port directly into the

modem. If the fanout cable is not long enough,

extend its configured port with an NTND91AA/AB

straight-through RS-232 cable and an A0351509

gender changer.

2 Using a twisted pair cable, connect the modem’s

telephone port to the port associated with the analog

line card on the Meridian 1 Option 11 switch.

3 Plug the modem’s AC cord into an AC outlet. Leave

the modem’s power switch in the OFF position.
