A combined telecommunications and data communications system operates by partitioning data wherein the PCM speech transmission data field is used to contain both digitized speech and other data in the same channel within a frame. Thus the system enables speech and data to be combined in a common information field and to be simultaneously transmitted in the same channel, frame by frame, through a digital switching network. The switching network contains a common port which has a digital interface connected to the port which digital interface can separate and combine the speech and the data fields. The digital interface is connected to a conference module which conference module receives the speech fields via a speech bus. The digital interface is further connected to a data base system which data base system receives the separated data fields via a data tone bus. Through the unique use of a digital interface for combining and separating speech and data fields from the information field of a channel, a conference module and a data base may both be connected to a single port thereby reducing the number of ports and network channels required for simultaneous conferencing and data base access.
