PHN 13.814 03-02-1992 Telecommunication system comprising a transceiver arrangement for mutually transmitting information in a DC isolated manner, and transceiver arrangement to be used in the telecommunication system. Prior-art telecommunication systems comprise transceiver arrangements structured, for example, as optocouplers for optically transmitting information, that is in a DC isolated manner. These optocouplers which may transfer relatively high frequency signals are expensive. When the signal to be transmitted has a low maximum frequency of about 200 Hz, a more cost-effective transceiver arrangement may be used, which comprises a transmitter means arranged for effecting a change of ambient temperature (a power dissipating resistor) and comprises a receiver means arranged for detecting the change of ambient temperature (an NTC resistor or a semiconductor element). In an advantageous embodiment transmitter means) and receiver means are used in integrated form deposited each on either side of a substrate. Fig. 1.
