Abstract
In a base station controller , each of header addition/deletion units through corresponding to base stations serially connected to a shared communication line adds to a communication signal transmitted to a particular base station a header having an address identifier specific to the particular base station to produce a communication signal cell. A cell collection/distribution unit cell-multiplexes the communication signal cells to produce a cell-multiplexed signal which is transmitted through a transmission unit to the base stations serially connected. Each base station checks the headers of the communication signal cells supplied thereto and acquires the communication cell having the address identifier specific to the base station itself. The remaining cells are transferred through the shared communication line to the next base station serially connected.
