Abstract
In a telecommunication switching system, incoming calls of various call types directed to a group of associated subscriber terminals are queued by call type and distributed on a priority basis. A separate queue is created for each call type and a table is provided which defines a number of priority levels and the call types to be served in each priority level. A priority frequency array is used for each of the terminals to assure that each terminal serves calls at the various priority levels with a prescribed frequency. When calls of different types but having the same priority level are waiting to be served, the oldest call will be selected on the basis of a time-of-day stamp recorded with each call on queue.
