CABLE TV-TELEPHONE COMPOSITE ACCESS SYSTEM AND ITS METHOD, AND MEDIUM FOR STORING COMPOSITE ACCESS PROGRAM

摘要

PROBLEM TO BE SOLVED: To attain efficient system operation by reducing an access time so as to eliminate the need for setting of troublesome access conditions for each system, and to select a specified access system at a prescribed time in matching with the operation purpose. SOLUTION: The incoming signal reception section 13 of a center 14 detects collision of incoming call signals to inform an access control means 11 of the state of an access channel. The access control means 11 selects an access system suitable for avoidance of collision among a contention system, a polling system and a group system prepared in advance based on the collision state, and sends the state of the access channel to an outgoing signal transmission section 12. The outgoing signal transmission section 12 multiplexes the state of the access channel to an access channel state storage area of a transmission frame and an access channel data storage area, and sends the result to a terminal 15. The terminal 15 makes an access request based on this information.
