Operation

7.4. Modem Mode

The Modem Mode provides features specifically related to modem communication. A Modem Mode Port can perform all functions normally available in Any-to-Any Mode. The Modem Mode is available to all RSM ports except the Network Port, and is the default port mode at the Internal Modem port.

When Modem Mode is selected, the Port Configuration menu will display three additional prompts, which allow you to re-define the modem reset string, initialization string, and hang-up string.

When a call is received, the unit will prompt the caller to enter a username and password. The RSM allows three attempts to enter a valid username and password. If a valid username and password is not entered within three attempts, or if the user does not respond to the login prompt within 30 seconds, the modem will disconnect.

Notes:

•When a Modem Mode port exits command mode, or the DCD line is lost while command mode is active, the RSM will pulse DTR to the modem. The unit will then send the user-defined modem command strings to make certain the modem is properly disconnected and reinitialized.

•When an external modem is installed at an RSM port, other ports can use the modem for calling out. To call out, invoke the /C command to connect to the port, then access the modem as you normally would.

•If desired, the Invalid Access Lockout feature can provide additional security for Modem Mode ports. When properly configured, the Invalid Access Lockout will automatically shut down a port whenever that port exceeds the user defined number of invalid access attempts. For more information, please refer to Section 5.4.2.
