9. 6. 20. 2 Unlocking the terminal for each call
Unlocking the terminal for each call allows the authorized user to enable any locked
terminal system so that he can make a single outgoing call.
After function code #36, the user dials his own internal user number and his personal
PIN. This activates his digit barring settings and the call charges are charged to his
charge counter: The called party sees the caller’s user number and not the number of
the user whose terminal is being used by the caller.
In this way an authorized user can use even unlocked terminals with his own settings.
For reasons of data protection no entry is made in the redial register.

Unlocking a third-party terminal
An authorized user unlocks someone else's terminal. After unlocking it, he can either
dial directly within the next 12 seconds or hang up and a number within 60 seconds.
The following remain locked and inaccessible:
• Operation of terminal settings
• Using the private phone book of the terminal’s user
• Dialling by name
Typical application: Unlocking non-personal terminals in publicly accessible premises
(meeting rooms, entrance lobbies, coffee-break areas).
