1. A method comprising:
- 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.

Abstract
An insertion apparatus receives a byte value from a signaling channel, locates a particular unused byte location within an overhead portion of a synchronous optical network (SONET) frame, and inserts the byte value from the signaling channel into the particular unused byte location. An extraction apparatus receives a synchronous optical network (SONET) frame, locates a particular byte location within an overhead portion of the SONET frame that is unused for SONET purposes, and captures a byte value from the particular byte location, wherein the byte value comprises a signaling channel.
