Abstract:
1. A configuration method for use by a substation to be coupled to a main station in an optical access network, said configuration method comprising: predefining for said substation a plurality of types of protocol; after being coupled to said main station, determining by said substation a bit-rate and a line-coding for a bit-stream transmitted over said optical access network by said main station, thereby providing a downstream line-rate and a downstream line-coding; and based upon at least one of said determined downstream line-rate and said determined downstream line-coding, selecting by said substation according to predefined rules and conditions a type of protocol out of said plurality of predefined types of protocol for said bit-stream; and activating said selected type of protocol and thereby enabling said substation to communicate with said main station according to said selected type of protocol, wherein the substation comprises an optical network terminator (ONT) of the optical access network and the main station comprises an optical line terminator (OLT) of the optical access network.
