What does DCC mean in a car 4S store?

[VonMatteo]

DCC refers to the Dial Control Center, with the three letters taken from English, and the full name is "Dial Control Center". The Dial Control Center is staffed with dialing specialists who are mainly responsible for sales, database management, expanding sales markets, and exploring customer needs. Here is some extended information: 1. Specific introduction: The so-called Dial Control Center is essentially established to meet the needs of data transmission by creating corresponding connections. It pre-establishes connections through routers across public switched networks, with the method of establishment being dialing. 2. Working principle: Generally, the Dial Control Center sets up two lines simultaneously when working, one as the main line and the other as a backup line. The role of the backup line is to provide assurance, ensuring that subsequent communications can proceed normally. In certain scenarios, connections between routers are only established when there is information transmission, thus ensuring that energy consumption remains at a relatively low level.
