11.4. Code Calling System Basic 
The CC (code calling/paging system) is connected to the system via the TMOM module.
For the paging input, several circuits can be assigned (except for MEET-ME mode).
Depending on the code calling/paging equipment, the following operating
modes are possible:
- DISPLAY: station number of the paging party is displayed
- VOICE ANNOUNCEMENT: talking facility to the paged party
- MEET-ME: the paged party answers with an individual answering code and is switched to the paging party by the code calling equipment. For this operating mode, a special answering circuit (station line) must be configured for the code calling equipment with the AMO SSC. It is assigned a special administration code (CCNO), which is not entered in the DPLN. If several paging systems are installed, each one must be assigned a special answering circuit for MEET-ME operation.
- MIXED MODE WITH CODE DIGIT: the operating mode (DISPLAY, VOICE, MEET-ME) or the type of code call (URGENT or NORMAL) is determined by the user, who dials a specific code ditit after the paged party's number.
- TRANSPARENT MODE: the paged party's number need not be entered
in the DPLN as a station number; it is transparently dialled through
to the code calling system as a B-block. This mode is possible in conjunction
with all operating modes mentioned above.
