Abstract
An apparatus comprising an optical line terminal (OLT) configured to transmit a bandwidth map (BWmap) for a plurality of burst signals to be transmitted by a plurality of optical network units (ONUs), wherein the BWmap comprises a plurality of allocations, and wherein each allocation comprises a start time for the allocation, a grant size for the allocation, and a header error correction (HEC) for the allocation.
Claims18
A method, comprising:
- receiving a bandwidth map (BWmap) from an optical line terminal (OLT), wherein the BWmap comprises a plurality of allocations for a plurality of burst signals;
- and
- transmitting at least one of the burst signals to the OLT in response to the BWmap,
- wherein each allocation comprises a start time for the allocation, a grant size for the allocation, and a header error correction (HEC) for the allocation, and
- wherein the start time and the grant size are both measured in four bytes.
