The present invention relates to the introduction of an outstation into an optical network. The optical network has a central station, and a plurality of previously introduced outstations which are optically connected to the central station. The network is operable in: a normal operating state in which data traffic is received from previously introduced outstations at a normal data rate; and, a set-up state in which the transmission of data traffic from the previously introduced outstations is restricted relative to the normal state, the method including the step of: when the network is in the set-up state, performing a set-up operation for introducing the outstation into the optical network, the set-up operation involving the transmission of set-up data from the outstation being introduced, wherein the set-up data is transmitted at a reduced rate relative to the normal operating rate.
A method of introducing an outstation into an optical network, the optical network having a central station, and a plurality of previously introduced outstations which are optically connected to the central station, the network being operable in:
An outstation for use with an optical network having a central station, the outstation having a normal operating state in which the outstation transmits data at a normal bit rate, and a set-up state in which the outstation transmits data at a reduced bit rate relative to the normal bit rate, wherein the outstation is configured to respond to a set-up message from the central station with a return messaged at the reduced rate.
A method of introducing an outstation into an optical network, the optical network having:
