schaltungsanordnung for transmission of telemetry exchange data over a pcm2a facilities equipped with cable

摘要

it is a schaltungsanordnung are given, and it is possible a temex transmission technology for analog parts from being able to usewith a digital system for point-to-point connections (pcm2a) are equipped.with a minimum of effort is to ensure that the principle of coupling and outtake of telemetry exchange data and the digital u00fcbertragungsprinzip remain unchanged.$a in the umsetzeinrichtungen leading ends of the analog teilnehmerleitungen are bandpau00dffilter and barrier). thus, the data of the speech signals temex separately.with the bandpau00dffiltern modems connected to the analog / digital implementation. a digital / analog implementation of telemetry exchange data.the digital outputs and inputs of the modems are connected directly with the control devices of the umsetzeinrichtungen.the telemetry exchange data with the nutzdatenkanal transferred, while the speech signals in compressed form on the two nutzdatenkanu00e4len is transferred.$a with this schaltungsanordnung can existing analog telemetry exchange transmission easily afterwards with a pcm2a system.similarly, a pcm2a system equipped transmission for temex transmission are set up.
