摘要：The communications system has an ISDN central switching station (VSTa), towhich at least one special-purpose terminal device (SE) provided with electroacousticaltransducers (MIC, LS) is connected and with which a mobile set (MT) is associated. Thespecial-purpose terminal devices (SE1, . . . , SEn) are provided with a processor (MP) and aswitching unit (SWUe), by means of which a connection between a terminal device (EGx)and the mobile substation (MT1; MT2; . . . ) associated with the special terminal (SE1; SE2; .. . ) can be switched through. To set up a call from the mobile set (MT1; MT2; . . . ) via theswitching unit (SWUe) to the terminal device (EGx), target addresses of the terminaldevice (EGx) are transferred to the special-purpose terminal device (SE1; SE2; . . . ), so thatthe special-purpose terminal device (SE1; SE2; . . . ) is suitable for extracting this

information and switching the connection through. Means for speech monitoring and/orrecording the switched- through telephone call are also provided in the special-purposeterminal device (SE1; SE2; . . . ). All the calls carried by the mobile set (MT) can thereforebe listened in on at the workstation of the person carrying the mobile set. Conferencecalls can also be switched, or functions (call recording, alarm, etc.) can be tripped byremote control from the mobile set (MT1; MT2; . . . ) to the special-purpose terminal

device (SE1; SE2; . . . ).
