Abstract
One embodiment of the present invention provides a system for accommodating time-division multiplexing (TDM) traffic in an Ethernet passive optical network (EPON). During operation, the system receives data from an upstream TDM channel at a remote node and stores received data in a segmentation buffer. The system encapsulates the data stored in the segmentation buffer into a packet. The system receives a message from the central node granting a TDM transmission window starting at a designated time. The system further communicates the packet to an upstream transmission mechanism within the remote node before the designated time, and transmits to the central node an upstream frame containing the packet at the designated time.
