11.6. Multiple Code Calling System CCM 
The multiple code calling equipment (CCM) is connected to the system via the TMOM
module. One
circuit on the TMOM must be configured per code pair (normal and urgent code calling).
Up to
15 code calling jobs can be entered via this circuit.
In the Meet-Me mode, the connection to the paging party is set up
by the OpenScape 4000; unlike single-call paging, multiple paging does
not have a special answering circuit.
If the 15 paging jobs are not sufficient, another TMOM circuit must
be assigned to the CCM for a further code pair. In this case, the paged
parties are assigned to one of the two code calling codes!
One code for normal code calling (CCMS) and one code for urgent code
calling (CCMSURG) should always be set up. In the Meet-Me mode, the answering
code (CCMANS) must be added.
Unlike single-call code calling, multiple code calling equipment also
uses CO trunks for paging.
Multiple code calling can be set up in the following modes:
- DISPLAY operation (call number of calling party is shown on receiver display)
- Meet-Me
In addition, the following features can be configured for the multiple code-calling system:
- Meet-Me operation with display
- Display sequence of meet-me number and calling party number can be reversed
- Calling party's number can be displayed left-justified or right-justified; display is filled or truncated accordingly
- Block separator characters and end-of-block characters can be defined
- CCM with code conversion
- Parallel ringing of exchange calls when FWD/FNANS activated to CCM in Meet-Me operation
- Priority signalling of urgent exchange calls for CCM in Meet-Me operation
- Recorded announcements for CCM in Meet-Me operation
- Multiple code calling of the same paging number
- Suffix dialling to CCM when busy
- Paging with on-hook handset internally and throughout network
