The present invention relates to a digital private branch exchange with direct internal switching. This digital private branch exchange with direct internal switching comprises an automatic exchange linked to the public network and connected by a signalling channel at least to the digital terminals each assigned an identification number, these digital terminals comprising transmission means for producing an internal or external call number, this branch exchange being provided for processing these two types of call, and is characterised in that it comprises: - forwarding means for routing an internal call number transmitted by a transmitter digital terminal towards the other digital terminals on the signalling channels, - receiver means in each of these terminals for detecting the correspondence between its identification number and the internal call number, - internal switching means for connecting the transmitter terminal and the digital terminal which has detected the correspondence of the numbers. This branch exchange is furthermore provided for the connecting up of an analog terminal.
