An automatic call distribution and voice line PBX switching system which includes a control complex having a first microprocessor based control circuit to selectively establish connections between access ports of a switching network. The control complex further includes a second microprocessor based control circuit which communicates data with a group of automatic call distribution positions, each of which is coupled to a different one of a first group of the access ports. The first and second microprocessor based control circuits communicate asynchronously through an interprocessor buffer circuit, and the number of automatic call distribution positions served by both the first and second control may be selected depending upon the particular application for the system.
