5.22.3.1. Activating and Deactivating a Network-Wide PIN 
Users with network-wide PINs only enjoy a subset of the current features
available with the standard, system-specific PIN feature. For example,
"name" keys (programmable keys) and individual speed dialling destinations
programmed at the home station cannot be accessed.
PINs can be enabled for network-wide use or limited to system-specific
(node-specific) use by setting the appropriate bit flag in the system's
feature bit string. It is not possible to activate both types of PIN
usage for PINs within the same PABX.
Users have two possible options for identifying themselves via PIN
within a OpenScape 4000/HiPath 4000 network:
- By entering the appropriate "APIN" code, i.e. entering the home station number followed by the assigned PIN (manual PIN)
- By inserting their chip card and entering their home station number
- from V2.0 by inserting the Smart Card
The code for deactivating the PIN (if necessary) is the same for all PIN
types. Users simply enter the "DPIN" code or pull out the card.
