The invention concerns a connection arrangement for supplying electricity to additional devices in a telephone installation by which it is possible to supply the devices with the optimal power in each case. In its input the telephone installation has a parallel device 35 with a specific DC current resistance curve which sets the largest acceptable input voltage for all loop currents, so that the greatest possible power can always be output. A priority network 36 connected after the parallel device 35 distributes this power to the individual consumers, where power not required is taken from one consumer to a consumer with the next lower priority. Thereby the input always provides loudspeaker and amplification terminal stages 38, 39 with lower priority and associated power restrictions with the greatest power in traffic. <IMAGE> |
