Integrated automatic call distribution facility and PBX system

Claim 2

An automatic call distribution and telecommunications switching system comprising: a. a switching network having a plurality of access ports including a first group of access ports coupled by a first group of lines to a group of automatic call distribution positions; and b. a control complex having: 1. first microprocessor control means selectively establishing connections between said access ports, thereby performing the functions of a telephone switching exchange, 2. second microprocessor control means for communicating data on data lines other than said first group of lines with the automatic call distribution group of positions, each of said positions being coupled to a different access port of said first group of access ports, and 3. means for transferring data messages between said first and second microprocessor control means, the second microprocessor control means including means for directing the first microprocessor control means to establish connections selected by the second microprocessor control means with said first group of access ports.

Claim 3

The system of claim 1 in which the second microprocessor control means includes: means for receiving data messages from the first microprocessor control means indicative of an incoming call at a first one of said access ports; and means for processing this data to produce a resulting data message and transferring said message to the first microprocessor control means, the first microprocessor control means including means for thereby establishing a connection between said first access port and a second access port from said first group of access ports which is designated by said data message.

Claim 4

The system of claim 2 in which said first microprocessor control means includes means for communicating a data message to the second microprocessor control means indicative of an established connection between a first access port and a second access port from said first group of access ports, and in which the second microprocessor control means includes means for processing this data message from the first microprocessor means and communicating with a position coupled to the access port of said first group of access ports.

Claim 5

An automatic call distribution (ACD) and private branch exchange telecommunications switching system comprising: a switching network having a plurality of incoming trunks, including a group of ACD trunks, and a plurality of lines, a first group of which are coupled to voice communication positions and a second group of which are coupled to ACD positions; a PBX control circuit including means for detecting calls on non-ACD incoming trunks and for directing the switching network to establish connections between said trunks and said voice communication positions and for communicating information concerning incoming calls on ACD trunks; an ACD control circuit communicating asynchronously with said PBX control circuit including means for receiving from the PBX control circuit information of incoming calls on ACD trunks and for processing said information to produce a connection command which is coupled to the PBX control circuit for directing the switching network to connect an ACD trunk having an incoming call with an ACD position; and means for communicating data between said ACD control circuit and the ACD positions on separate data lines.

Claim 6

An automatic call distribution (ACD) and private branch exchange telecommunications switching system comprising: a switching network having a plurality of incoming trunks, including a group of ACD trunks, and a plurality of lines, a first group of which are coupled to voice communication positions and a second group of which are coupled to ACD positions; a PBX control circuit including means for detecting calls on non-ACD incoming trunks and for directing the switching network to establish connections between said trunks and said voice communication positions and for communicating information concerning incoming calls on ACD trunks; an ACD control circuit communicating asynchronously with said PBX control circuit including means for receiving from the PBX control circuit information of incoming calls on ACD trunks and for processing said information to produce a connection command which is coupled to the PBX control circuit for directing the switching network to connect an ACD trunk having an incoming call with an ACD position; and means for communicating data between said ACD control circuit and the ACD positions on separate data lines.

Claim 7

The system of claim 4 which further comprises a group of supervisory positions coupled to some of the lines in said second group of lines and in which the ACD control circuit includes means for communicating data to said supervisory positions, which data is at least different in part from that data communicated to the ACD positions.

Claim 8

The system of claim 4 in which the ACD control circuit includes means for generating status information indicative of connections established by the switching network between the incoming ACD trunks and the second group of lines.

Claim 9

An integrated ACD and PBX system for a multiplicity of communication lines comprising: switching means for interconnecting pairs of said lines in response to interconnection instructions; PBX control means for producing said interconnection instructions and coupling them to the switching means, an interconnection instruction for an incoming communication on a line in a first group of said lines being determined by the PBX control means and an interconnection instruction for an incoming communication on a line in a second group of said lines being received by the PBX control means; ACD control means for producing an interconnection instruction for an incoming communication on a line in the second group of lines and for coupling said instructions to the PBX control means; and means for communicating data concerning an interconnection made by the switching means in response to said instruction to a position by means other than said interconnected lines.

Claim 10

An integrated ACD and PBX system for a multiplicity of communication lines comprising: switching means for interconnecting pairs of said lines in response to interconnection instructions; PBX control means for producing said interconnection instructions and coupling them to the switching means, an interconnection instruction for an incoming communication on a line in a first group of said lines being determined by the PBX control means and an interconnection instruction for an incoming communication on a line in a second group of said lines being received by the PBX control means; ACD control means for producing an interconnection instruction for an incoming communication on a line in the second group of lines and for coupling said instructions to the PBX control means; and means for communicating data concerning an interconnection made by the switching means in response to said instruction to a position by means other than said interconnected lines.
