Users must always entertheir valid PIN beforehand. They can do so both on one of their own terminals andon a third-party terminal on the same communication server or within a PISN.Detailed DescriptionThe user dials the function code #46, keys in his user number and enters his per-sonal PIN. This deactivates his external digit barring; the terminal is also unlocked,and the user obtains the exchange dial tone. He can then make an external call,which is automatically charged to his private charge counter.Note:To prevent unauthorized persons from making private calls at other user’expense, all private phone calls must be made with a PIN, even whenusers are using their own terminals. The procedure is the same for bothlocked and unlocked terminals.Function in prefix diallingTab. 286Private calls with PIN: FunctionOther properties:•During a call the function can also be made from an enquiry call.•The called party sees the caller’s user number and not the number of the userwhose terminal is being used by the caller.•For reasons of data protection no entry is made in the redial register.•Unlike with #36 (making calls with your own settings but on a third-partyphone) you cannot hang up after activating the function and then prefix dialwithin 60 seconds.•The same PINs are used as for the phone lock.•Users without their own terminals can be defined as virtual users, and can thenalso use this feature.FunctionFunction codePrivate call with PIN from one of one’s own termi-nals or from a third-party terminal#46
