ABSTRACT:
A method for determining a status of a buffer for use in converting between a standard SONET and a non-standard SONET frame is presented. The method determines the buffer's almost empty or almost full status based on a length of a transport gap of the non-standard SONET frame, wherein the standard SONET frame is formatted as a STS-N, and the transport gap of the non-standard SONET frame has been rearranged to provide a longer non-data region at the beginning of the non-standard SONET frame. The method then uses the buffer's almost empty or almost full status to trigger positive or negative stuffing. The method is used for maintaining communications when using asymmetrical gapping structures.
