WDM-to-switch interface unit
First Claim
1. A WDM-to-switch interface unit comprising a WDM multiplexer/demultiplexer (mux/demux) for interfacing to a WDM optical network, a switch interface element for interfacing to an external switch unit, and a first conversion component disposed between the WDM mux/demux and the switch interface element for converting one or more layers of a management protocol in the optical network into corresponding layers of a management protocol of the external switch unit.

23. A method of interfacing between a WDM optical network and a plurality of external switch units having different switching platforms, each external switch unit having at least one associated conversion element connected to it, the method comprising the step of selectively directing optical signals to the conversion elements connected to the respective switch units, and, at the conversion elements, converting one or more layers of a management protocol in the optical signals directed to the respective conversion elements into corresponding layers of a management protocol of the external switch unit connected to the respective conversion elements.
