A method, system, and computer program for implementing TDD in an EPoC network. Multiple PHY-layers for coax or HFC segments operate cooperatively to establish a constant delay for an upstream path, and a constant delay for a downstream path, resulting in a constant RTT rangeable by either: an EPoC CLT (116); or an EPON OLT with an EPoC OCU. The delay for at least one PHY-layer is not established as constant, but suffers variable delays (100), while at least one other PHY-layer establishes delays which are Complementary (102) to said variable delays. |
