ABSTRACT:
In a method for controlling communication paths multiplexed in a communication medium connecting first and second communication devices, each of which devices can simultaneously perform a plurality of works. It is determined whether a communication request from one of the works is a normal communication request or an emergency communication request. It is determined whether or not the number of communication paths which are now in use is less than a first predetermined number when it is determined that the communication request is a normal communication request. An idle communication path is allotted to the communication request when it is determined that the number of communication paths in use is less than the first predetermined number. It is determined whether or not the number of communication paths which are now in use is less than a second predetermined number greater than the first predetermined number and equal to a maximum number of communication paths available in the communication medium. An idle communication path is allotted to the communication request which is determined to be as an emergency communication request when it is determined that the number of communication paths in use is less than the second predetermined number.
