METHOD OF INTRODUCING AN OUTSTATION INTO AN OPTICAL NETWORK AND OUTSTATION THEREFOR
First Claim
1. 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:
- 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 that is being introduced, wherein the set-up data is transmitted at a reduced rate relative to the normal rate.

Abstract
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.

12. 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.

13. 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, wherein the network has a normal operating rate at which the previously introduced outstations transmit data to the central station, the method including the steps of;
transmitting set up data from the outstation being introduced to the central station; and
, using the set up data to perform at least one set-up operation for introducing the outstation into the optical network, wherein the set up data is transmitted at a reduced rate than is lower than the normal operating rate.
- a central station and a plurality of previously introduced outstations which are optically connected to the central station, wherein the network has a normal operating rate at which the previously introduced outstations transmit data to the central station, the method including the steps of;
