Abstract: Various embodiments of the present invention disclose a DOCSIS protocol-based access method, apparatus, and system. A first PON physical layer module is disposed inside or outside a CMTS device; the CMTS device receives DOCSIS protocol-based data, converts the DOCSIS protocol-based data into PON physical layer format-based data by using the first PON physical layer module, and sends the PON physical layer format-based data to a CMC through an optical distribution network; and the CMC receives the PON physical layer format-based data, converts the PON physical layer format-based data into DOCSIS physical layer format-based data, and sends the converted data to a terminal device. The solution provided by various embodiments of the present invention is applicable to a DOCSIS system.

Abstract: The present invention discloses a data transmission method, apparatus, and system, which are used to reduce a delay of user uplink data and improve network performance in an HFC network. The method includes: determining, by a cable modem termination system physical layer CMTS PHY layer according to uplink resource assignment information configured by a cable modem termination system Media Access Control layer CMTS MAC layer separately for each cable modem CM of multiple CMs, a time slice that needs to be occupied when uplink data sent from a CM connected to the CMTS PHY layer, is forwarded to the CMTS MAC layer; and forwarding, by the CMTS PHY layer to the CMTS MAC layer on the determined time slice, the received uplink data that is sent, by using the uplink resource assignment information configured by the CMTS MAC layer, by the CM connected to the CMTS PHY layer.
