7. Operation
7.1. SRM Operating Modes
The SRM-100 provides three separate operating modes; the User Mode, the Command Mode,
and the Unsecured Mode.
7.1.1. User Mode
The User Mode is activated when a caller enters a User Password at the login prompt. The
User Mode only allows the caller to access the secure device which is connected to the serial
modem port. The User Mode does not allow access to configuration menus or the Password
Directory.
7.1.2. Command Mode
The Command Mode is activated when a caller enters the System Password at the login prompt,
or when a local user enters the SRM Command Mode via the Console Port. The Command
Mode allows access to all SRM-100 configuration menus, and is used to define passwords and
select operating parameters as described in Sections 5 and 6 of this User's Guide.
7.1.3. Unsecured Mode
When the Unsecured Mode is active, the SRM will function like a normal, unsecured modem.
Callers will be allowed to access the secure device without entering a password. The
Unsecured Mode is activated by placing SetUp Switch 8 in the Up position (see Section 4.3.7),
or by accessing the General Parameters Menu (see Section 5.2) and disabling the Security
Mode. Note that when the Unsecured mode is active, you will not be able to access the
Command Mode via modem; you will only be able to access the SRM Command Mode via the
console port.
In order to return to password-protected operation, you must either access the Command Mode
via the Console Port, and then use the General Parameters Menu to enable the Security Mode,
or enable the Security Mode by placing SetUp Switch 8 in the Down position, and then
reinitialize the SRM unit as described in Section 4.4.
7.2. Password Functions
The SRM-100 features three different types of passwords; the System Password, the Console
Port Password, and the User Passwords. The System Password allows system administrators to
invoke configuration commands and review connection activity. The Console Port Password
allows access to the SRM Command Mode via the Console Port. The User Passwords allow
callers to access the secure device that is connected to the SRM's serial Modem Port .
