  • receiving a byte value from a signaling channel;

    locating a particular unused byte location within an overhead portion of a synchronous optical network (SONET) frame, wherein locating the particular unused byte location comprises;

    switching to an interface buffer storing the byte value when the particular unused byte location is available to be written, said interface buffer being one of a plurality of interface buffers corresponding to a plurality of signaling channels, said plurality of interface buffers being switched to match the plurality of signaling channels to corresponding byte locations at a data rate of a SONET service comprising the SONET frame; and

    inserting the byte value from the signaling channel into the particular unused byte location.
