Chapter 7 - Callback Security and Remote Configuration

7.1Introduction

This chapter describes how the MultiModem’s 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.

7.2Callback 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 long). You use the modem's LOGIN Password and the Set-Up Password plus special Callback commands to access this memory. The memory is thirty numbers long and replaces your modem's normal phone number memory.

Each number is 35 characters long and can contain commands as well as phone numbers. You need to set up your modem with the numbers and codes as part of the dial back initialization procedures. Your modem will also remember if the incoming call was reliable or not, and make the call back accordingly.
