Optisches System zum Anschluss der Teilnehmereinrichtungen an eine Vermittlungszentrale eines Telekommunikationsnetzes mit interaktiven und nichtinteraktiven Diensten

摘要

An illustrative embodiment includes: - an exchange (EX) including junctors (ET0, ... ET31), a connection network (CN), and a control unit (CU); - an optical distribution network (DN); - and subscriber installations (CPN0, ..., CPN255). The non-interactive services (SD, CY) are connected up to the control junctor (ETE0), so as to transmit non-interactive service signals to all the subscriber installations (CPN0, CPN10, CPN20) which are monitoring the wavelength (Lc) of the control junctor. These installations may therefore benefit from these services without each having to establish a communication, and therefore without occupying one junctor per subscriber installation. Each subscriber installation (CPN255) which requests a non-interactive service during an interactive communication retains the wavelength (Ld) and the junctor (ETE31) which were allocated to it for the interactive communication. Application to wide band telecommunications networks.
