It is proposed to use several distributed conference units (KE1, KE2) in a conference system (KS) for carrying out conferences, particularly broadband conferences, and to mix the signals (S1 ... S4). The signals (S1 ... S4) from subscriber stations (T1 ... T4) involved in the conference are not necessarily mixed in a single conference unit, rather the mixing is distributed to several conference units (KE1, KE2). In this way it is possible to mix signals that have a partially common transmission path in the communication system into a component signal (12) by means of a first conference unit (KE1). This mixed component signal (S12) is then transmitted to a second conference unit (KE2) and is mixed in this second conference unit (KE2) with one or more other signals (S3, S4). Sincethe mixed component signal (S12) during the transmission occupies the same bandwidth as a single signal (S1 ... S4), the transmission capacity of the communication system (KS) needed for the conference can be kept small.
