ABSTRACT:
A technique for delivering bursted native media data flows over an Ethernet physical layer between a head-end and an outstation is disclosed. In one embodiment, the technique is realized by operating a device in a default bypass mode at the outstation; receiving a first command wherein the first command is one of a directed command and a multicast command to an address for exchanging Ethernet frames with an Ethernet physical layer; and receiving a second command wherein the second command is one of a multicast command and a directed command for exchanging native data flows with the Ethernet physical layer. The bursted native media data flows may be TDM data flows and the device may be a TDM device wherein the commands may be pause signals or burst signals.
