Abstract

A transmission system for internal and external data traffic of a telecommunication system, particularly telephone characterized in that the data is transmitted in a way known as frequency modulated signals within a system in a special internal frequency band, because the Assigned indoor modems or subscribers (T-Mo), which are tuned to the indoor frequency band, are associated with subscriber stations (Tin) authorized to take part in data traffic, and why for external traffic With data from and outgoing in the usual frequency band, modems assigned to the connections (A-Mo) have been provided that serve to convert the frequencies of the incoming and outgoing data.
