Reference Guide for the Model RM356 Modem Router
1-4 Introduction
Security
The Model RM356 Modem Router is equipped with several features designed to maintain security.
These security features are described in this section.
Calling Line Identification
The use of Calling Line Identification (CLID or Caller ID) ensures that incoming calling numbers
are checked against known numbers before a call is answered and access is granted, thus
providing a first level of security. In many areas, you must specifically request that CLID
be enabled by the telephone company for your line. In some regions, CLID may not be available.
PAP and CHAP Authentication
For connecting to other routers, the Model RM356 router supports two authentication protocols:
Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol
(CHAP). PAP sends the user name and password in plain text. CHAP scrambles the password
before it is sent over the wire. Although CHAP provides better security, PAP is readily available
on more platforms.
Callback
For security and simplified cost accounting, the router implements Callback. When a remote user
dials in, the router can disconnect the call and call the user back so that any further call charges are
incurred by the location of the router. The caller can provide the callback numbers or, for security,
the router can be programmed to call back a predetermined number.
Management Support
The router is designed to be installed and made operational within minutes after connection to the
network.
If you are a PC user, the FirstGear software lets you easily configure the unit from the Windows
environment.
If you are a Macintosh, UNIX, or PC user, you can connect to the built-in Manager interface,
which can be accessed through a terminal connected to the Manager port or through a Telnet
session across the network. The built-in Manager interface manages and configures the
unit through an easily understood screen process.
