ABSTRACT:
A local area network is used to interconnect media equipment, such as telephones, VoIP telephones, a media server, etc., located at geographically distributed sites of an optical communication system. The local area network may be implemented within an optical services channel carried by a WDM optical communication link. This may provide the needed connectivity at low costs and may allow conference calls to be accommodated.
