ABSTRACT:
A PBX switching system is described in which a queue is used to provide sequential serving of attendant directed calls. This is accomplished by sequentially storing the identity of the calling circuit for each newly arrived attendant directed call in an attendant queue. When an attendant position becomes available, the calling circuit identity stored longest in the queue is used to directly select the associated calling circuit and to connect this circuit to the attendant.
