Overview
NOTE
This chapter supports the
operation of dial access security
for the COMSPHERE 3800
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 an optional feature that allows
you to control who has access to your COMSPHERE
3800 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. COMSPHERE 3800 Series
modems can store a maximum of 20 passwords. (A 
Model 3811 with the optional Password Expansion
Feature can store up to 3000 passwords.) Each password
is assigned a series of parameters that determine the type
of security protocol applied to it. This protocol is
established in the Security branch of the Top-Level menu.
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 section of this
chapter and the Security Configuration Options section in
Chapter 9.
The COMSPHERE 3800 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.
