发明名称 Method for activating a holding position for a calling subscriber in a telephone exchange
摘要 The method according to the invention for activating a holding position for a calling subscriber in a telephone exchange is intended to enable the desired subscriber, who, when an intrusion connection exists or a call waiting facility has been initiated, already has a call in progress, to disable the intrusion connection or call waiting facility initiated by a further different subscriber. He is then able to continue a call which is very important to him without interruption and thereby switches the further caller to a holding position. This holding position is signalled audibly or visibly to the further calling subscriber, where visible identification can moreover also be provided for the desired subscriber.
