SERIES II INTELLIGENT DATA/FAX MODEMS

7. Callback Security and Remote Configuration

7.1 Introduction

This chapter describes how the Series II Modem Callback and Remote

Configuration features operate. These features use a multilevel security system, which involves the use of LOGIN Passwords, Setup Passwords and Remote Escape Characters.

The primary level security code is the modem’s LOGIN Password. Once this password is entered, other passwords can be used. For instance, entering the LOGIN Password will allow you to enter the Setup Password, which, in turn, allows you to enter Callback Passwords and dial back phone numbers. Callback Passwords tell your modem what dial back phone number to call.

The Remote Escape Character is the key to using the Remote Configuration feature. The Remote Escape Character lets you enter Command mode via a remote call, so that you can enter AT commands just as if you were locally connected. You must also enter your modem’s Setup

Password. The Remote Escape Character is contained in S-Register S13.

7.2 Callback Feature Description

The Callback feature protects your network from unauthorized access and helps control long distance costs. By use of Callback Passwords and dial back phone numbers, you can have your modem "dial back" remote locations immediately after being called. A special command

(Enable Callback #DB ) turns your modem into a Callback security modem. The Callback Password/Phone number entry is protected by two-level security (your modem's LOGIN Password and Set-Up

Password) that keeps unauthorized personnel from changing parameters. When you first get your modem, you need to change both security level codes to your unique settings.

The Callback Passwords and dial back phone numbers are in a special

Callback Password/dial back phone number memory (30 numbers
