Embodiment Construction
[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0042] see figure 1 As shown, in the EOC ONU system of the embodiment of the present invention, the ONU and the CBAT are integrated into a whole device. For EPON system, this equipment is ONU equipment, but for EOC system, this equipment is CBAT equipment. figure 1 Among them, ONU is not only limited to EPON, but also applicable to xPON.
[0043] For the EOC ONU hardware structure used to realize the line identification function in the embodiment of the present invention, refer to figure 2 As shown, the EOC function and the EPON ONU function are integrated in one device. The device contains four hardware modules: EPON chip, Ethernet switch chip, EOC chip and CPU. The management control interface of the Ethernet switch chip is connected to the CPU, the uplink port of the Ethernet switch chip is connected to the Ethernet side interface of t...
