  • Management of units housed in subtended equipment shelves
    Patent number: 9008130
    Abstract: A remote enclosure houses multiple subsystems. A first subsystem is coupled to a central office over a high-speed communication channel such as an OC-3 channel. The first subsystem extracts a downstream message from a first embedded operations channel included in the high-speed communication channel. The first subsystem also, when the downstream message is targeted to a first unit included in the first subsystem, forwards the message to a unit that processes the message for the first unit. When the message is not targeted to any unit included in the first subsystem, the first subsystem forwards the downstream message to another subsystem housed within the remote enclosure via a second embedded operations channel included in a second communication channel. The second subsystem is subtended from the first subsystem and is connected thereto by the second communication channel.
