Dial Access Security12

Overview

NOTE

This chapter supports the operation of dial access security for the COMSPHERE 391x Series modems. This chapter is self supporting and can be removed to prevent unwanted knowledge of dial access security operation.

Although the security functions described in this chapter are designed to prevent unwanted user access to your network, the company recognizes that no security system is infallible.

Dial Access Security is a feature that allows you to control who has access to your COMSPHERE 391x Series modem and ultimately your host DTE.

To take advantage of this security feature, you must create a database of passwords which are stored in the modem’s nonvolatile memory. The Model 3910 can store a maximum of

20 passwords while the Model 3911 can store up to 3000 passwords. Control of security functions is established in the Security Configuration Options group which is located in the Configuration branch of the Top-Level menu. These areas are described in the Security Branch and Security Configuration Options sections of this chapter.

The COMSPHERE 391x Series modem uses an outbound and inbound method of security known respectively as Originate Access and Answer Access security. Both methods of security require some type of password entry whether it be included as part of an AT command dial string or entered directly from a remote user’s DTE.
