| 摘要 |
Embodiments of the present invention provide a method for transmitting data, a Coaxial-cable Line Terminal (CLT) and a Coaxial-cable Network Unit (CNU). The method, applicable to a coaxial network including at least one Coaxial-cable Line Terminal (CLT) and multiple Coaxial-cable Network Units (CNUs), the CLT being connected with each of the CNUs through a shared coaxial medium, includes: transmitting, by the CLT, a control message to each of the CNUs. The control message contains information of an uplink transmission period of time that can be occupied by each CNU during one period, and uplink transmission periods of time for the CNUs are not overlapped with one another so that uplink data transmitted by the CNUs do not collide with each other. The embodiments of the present invention allocate a shared transmission medium in an EPCN system, and guarantee normal physical layer communications of the EPCN system.
