Abstract: By acquiring the active and/or inactive state of multimedia communication terminal apparatuses (TV1. . . TVn) connected to a multimedia communication network (BPON), optimal use can be made of the switching-oriented and transmission-oriented resources (vr) of the multimedia communication network (BPON). In the multimedia communication network (BPON), unused allocated resources (zr) are automatically again released or, respectively, are cut off from a request of resources (zr), dependent on the acquired active and/or inactive states.

Abstract: A digital cordless telephone system comprises a multiplicity of subscriber cordless handsets (HS's) with a subscriber number of a private automatic branch exchange (PABX) being assigned to one or more of the HS's, a plurality of base stations (BS's), each of the BS's being coupled with one or more of the HS's by radio channels for controlling a radio link between each of the BS's and each of the HS's, and a system connecting unit coupled with the BS's and the PABX for allowing only authenticated HS's to initiate outgoing calls and for keeping track of each of the HS's to set up calls for the HS's whenever the HS's are within the service area of one of the BS's.
