Abstract

A terminal equipment is connected in a first optical network and connected, via a conductive path, to a predetermined one of a plurality of communication devices connected in a second optical network. The above terminal equipment includes an optical transmitter/receiver unit, a controller for controlling the above predetermined one of the communication devices in order to monitor the communication devices connected in the second optical network, and a selector unit. This selector unit transfers, via a control path coupled to the predetermined one of the communication devices, a poling signal from the first optical network to a specified one of the communication devices addressed by the poling signal, and sends back, to the first optical network, control data which shows a status of the specified one of the communication devices connected in the second optical network and which is received, via the control path, from the specified one of the communication devices.
