5.16.11.2. User Interface 
The user interface is essentially influenced by the following factors.
- Dialing the PIN with preselection (PCODE APIN10) or suffix dialing
- Entry of the PIN necessary in the case of PININT or PINNW
- Signaling of the calling party at the called party after identification via PIN entry.
- The PIN is dialed in preselection:
Before the number is dialed, the COPIN for PINWM is activated via the own code (APIN10). This procedure is absolutely identical to identification via digital analysis result.
- The PIN is dialed in suffix dialing:
The following procedure applies to the Anate and Digite terminal devices:
- The calling party dials the complete number of the called party
- Calling party hears the Recall-Dial tone
In the event of:
- PININT activated: Calling party dials the correct PIN code
- PINNW activated: Calling party dials home station number, followed by # , then the correct PIN code and # again.
- Calling party hears the Confirmation tone
