1. Integrated communication system containing a narrowband communication network with narrowband switching facilities (1), a broadband switching network with broadband switching facilities (17), and digital broadband distribution switching networks with broadband distribution facilities (14), the broadband switching and distribution facilities being controlled fron the narrowband switching facilities, characterized in that in the case of a narrowband switching facility which has a digital switching network (1) and terminal modules (2, 4) connected therewith and wherein the control facilities are spatially distributed to the terminal modules (2, 4), there is provided an additional terminal module (16) which is connected to the digital switching network (1), contains the control facilities for one of the broadband switching facilities (17), and is connected via the digital switching network (1) to the narrowband communication network for the exchange of the signalling and control information necessary to handle the calls in the broadband switching network. |
