Lockout occurs when:

• A user does not disconnect after the other party on a call disconnects.

  • The user receives the dial tone for 10 seconds, and then receives the intercept tone for the interval that you administer.

  • You can administer the system to play a special howler tone before the system takes the telephone out of service.

  • If the handset remains off-hook, the system takes the telephone out of service.

• A user pauses for 10 seconds between digits when the user dials numbers.

  • The user receives intercept tone for 30 seconds.

  • If the handset remains off-hook, the system takes the telephone out of service.

The telephone remains out of service until the user disconnects.
