Abstract
An automatically configurable optical connection system for connecting customer premises networks to a switching center of a telecommunication network includes an optical distribution network connecting all central office termination equipment optical senders to all customer premises network optical receivers and connecting all customer premises network optical senders to all central office termination equipment optical receivers. A control unit assigns a different wavelength to each customer premises network communicating at a given time, this wavelength representing an available central office termination equipment which is not the control central office termination equipment. To enable automatic system configuration each central office termination equipment sends cyclically an identification message and each inactive customer premises network listens out cyclically at each wavelength available to the central office termination equipments and memorizes the relationship between the wavelengths and the central office termination equipment identities, marking the control central office termination equipment wavelength. The system is for use in broadband telecommunication networks.
