Abstract: A CDMA transmitting and receiving apparatus with multiple applied interface functions and a method thereof is provided. The apparatus is center around a system control unit. The system control unit includes a plurality of interface drivers that works with a base band signal processing unit for converting information of different kinds to a base band signal and then transmits through a communication transceiver. Alternatively, the system control unit also transmits information to at least one of the connecting interfaces when the communication transceiver receives a base band signal. Moreover, the apparatus also provides integration to information of different kinds allowing flexibility and adaptability thereby enabling an efficient and secured use of network management interfaces within a communication system.
