Central telecommunication system with a community antenna system

Abstract

Abstract A central telecommunication system built onto a community antenna system in which, between the extensions (2) and the main station (1), a wired return traffic chain with an operating frequency band outside that of the community antenna system is built as an extension to the latter, and the inputs (7) of the return traffic chain connected to the extensions (2) are connected to the main line summing filter (9) of the main station via directionally-coupled summing elements (8) and summing filters (6), bypassing the units participating in signal transmission in the main direction, and the main line summing filter (9) has an output allocated to the return traffic chain. <IMAGE>
