Abstract

The signaller has a connection for a signal generator (15), and an evaluator (19) connected directly at the ISDN connection (9,3). The evaluator evaluates only call information contained in transferred ISDN data contained call information. A controller (21) is controlled by the evaluator and activates the connected signal generator. The signal generator is preferably formed as an analog operating, acoustic alarm.
