摘要： An Ethernet-PON that accommodates real-time broadcast/image signals and provides security for broadcast/image signals, allows user authentication without a CAS. An OLT in the Ethernet-PON switches digital broadcast/image data signals from a broadcaster according to respective broadcast/image selection information of users, and scrambles the switched broadcast/image data on a user-by-user basis. The scrambled data is multiplexed and converted to a broadcast/image optical signal, which is transmitted, combined with a communication signal from an IP network, to ONTs through an optical splitter. The ONTs select broadcast/image data from the broadcast/image signals according to the respective broadcast/image selection information.

摘要： MAC (Media Access Control) for an EPON (Ethernet Passive Optical Network system) defined in an IEEE (Institute of Electrical and Electronics Engineers) 802.3ah EFM (Ethernet in the First Mile) standard is implemented using general MAC based on an IEEE 802.3 standard. LLID (Logical Link ID) information is inserted at a predetermined position of a frame outside its preamble and the frame containing the LLID information is transferred to a higher layer so that general MAC can be used as MAC for the EPON system. A physical layer of the EPON system contains LLID information within a preamble and transfers the preamble containing the LLID information. An RS (Reconciliation Sublayer) configures a new Ethernet frame by inserting the LLID information at a predetermined position of the Ethernet frame outside the preamble. The RS transfers the new Ethernet frame to a higher data link layer of the EPON system. The data link layer transfers the new Ethernet frame containing the LLID information.
