PREFERRED-NONPREFERRED TRUNK GATING EQUIPMENT FOR AUTOMATIC CALL DISTRIBUTION

摘要

A system is disclosed for automatically distributing calls on groups of incoming lines through line and trunk link frames to teams of operator positions under control of markers. Frame and position gate circuitry is provided for serving the calls in the approximate order of their arrival. Position trunk gate and marker circuits balance the workload among operators by equalizing call distribution through a plurality of trunk link frames to both heavily and lightly occupied teams of operator positions selectively serving a plurality of different classes-of-calls. Position trunk and class control circuits convey data from the markers to advise operators of the classes of the received calls.
