Abstract

An optical connection system for connecting customer premises networks to a switching center of a telecommunication network providing interactive and non-interactive services includes a switching center comprising central office termination equipments, a connection network, a control unit, an optical distribution network and customer premises networks. Non-interactive services are connected to the control central office termination equipment so that non-interactive service signals are sent to all customer premises networks on standby at the control central office termination equipment wavelength. These customer premises networks can therefore use these services without having to set up a call individually and so without having to busy a central office termination equipment for each customer premises network. Each customer premises network which requests a non-interactive service during an interactive call retains the same wavelength and the same central office termination equipment assigned to it for the interactive call. The system finds an application in broadband telecommunication networks.
