摘要：The invention relates to a private branch exchange with a collective line, acontroller (CC, LTUC1, PCB11), which is allocated to the collective line, re-directing callsfed to the collective line to internal terminals (T21...T2X) of a collective line group. Thecontroller continuously determines traffic load values and compares these with a first
upper limit and with a second lower limit. If the first limit is exceeded, connections are setup to terminals which were not originally allocated to the collective line, and this re-allocation is signalled to these terminals. If the value falls below the second limit,connections are set up to terminals which were originally allocated to the collective lineand the ended allocation is signalled to them. The telephone private branch according tothe invention exchange implements a dynamic allocation of terminals to a collective lineand is thus suitable for different traffic loads.
