24 PROTON 206/308 V1 System Manual
• If CDC is activated, then system gives warning beeps after time = CDC warn timer. After the warning tone,
the system waits for time = CDC good-bye timer before releasing the connection forcefully.
• CDC can be activated on selected stations.
• CDC can be activated for either day, or night, or both.
• In case of transferred call, the CDC timer gets reset and starts again afresh on the transferred station.
• It is also possible to just warn the user without disconnecting his call. In this case, the user gets the beeps
after the programmed time but his call does not get disconnected.
• If Barge-in/Raid feature is used on a station on which CDC is activated then the time for which Barge-In/Raid
was done will not be counted.
