Security
Capacity
The modem stores in nonvolatile memory the password, security level,
callback phone number, and status information for 50 users.
Operating without High Security
The modem is factory set with security disabled. In this mode the local
DTE is connected to the local modem as usual, but the command to
enable or view the status of the security feature will be accepted and
processed.
Operating with High Security
With high security enabled, each user must follow the appropriate logon
procedure. The procedure for remote users is determined by their
assigned security level. Upon termination of the connection, the secured
modem waits for the next call and password sequence. A local user must
logon to the secured V.3600 to use the unit.
If a power outage occurs, the logged -on user must logon again when the
power is restored. For optimum security operation a reliable connection
should be used.
Security Levels
The V.3600 provides three levels of security to prevent unauthorized
access by a remote user.
Level 1: Password Only
This is the lowest level of dial-up security. The user dialing in is
prompted for an ID and password; if invalid, the modem hangs up.
Level 2: Password with Callback
This security level also accepts only calls from preset telephone
numbers. After the user enters a correct ID and password, the modem
looks up the telephone number and calls the user back at that number.
Level 3: Password with Callback and Password
Re-Entry
This is the highest level of security and is similar to Password with
Callback except that after the user answers the callback call, the modem
prompts again for the password.
