Abstract:
A transmission bandwidth sharing apparatus accommodating a plurality of terminals, said apparatus comprising:a constant bit rate circuit; means for registering said terminals meeting the requirement that each maximum transmission bit rate of the registered terminals is equal to or lower than the maximum transmission bit rate of said constant bit rate circuit, and the sum of data transmission capacities of valid signals from the registered terminals is equal to or smaller than the data transmission capacity of the constant bit rate circuit at a predetermined cycle; and means for allocating a timing in an invalid signal transmission period of one of said registered terminals for use as a transmission timing of valid signals from the other registered terminals, to provide a fixed valid signal transmission period to each of the registered terminals at said predetermined cycle and thereby to allow said constant bit rate circuit to be shared among the registered terminals and periodical burst data provided by each of said terminals are transmitted through said constant bit rate circuit bandwidth that is determined to guarantee the maximum transmission rate among transmission rates of said burst data.
