Function
Initial operation
Before the telephone can be used, it must be logged into the D- network (Digital-network). For this purpose, the SIM card (Subscriber Identification Module) is required.
After inserting the SIM card (already in telephone transmitter/ receiver with permanently installed telephone depending on system) and then switching on with the On/Off switch on the telephone handset (A34) or on the portable CTEL (A34/6) it is necessary for the user to enter the four to eight digit PIN code (Personal Identification Number) when requested. This number prevents unauthorized use of the card and protects against misuse Incorrectly entering the code three times in sequence disables the card, which can be re-enabled with the aid of a personal eight-digit re-enable number (PUK, personal unblocking key or also super PIN). This allows entry of a new PIN number.
If the PUK is entered incorrectly ten times in sequence, the card is rendered unusable and it is necessary to apply to the provider for a new card.
If the number is entered correctly, the telephone logs into the service provider's network. The telephone is then ready for use.

In order to transfer information to the bus systems, a so-called interface (adapter) to the bus system in question is required.
