Which of the following access network products can provide ADSL access methods?

What are the fiber types connected to the MA5680T GPBD port?

Is the following description correct? The access network upgrade loading file transfer can use FTP, TFTP, or SFTP, and FTP is recommended.

Regarding EPON, which of the following descriptions is incorrect?

A.In the upstream direction from the ONU to the OLT, each ONU uses the broadcast mode to share the upstream bandwidth.
B.The downstream data stream from the OLT to the ONU is encapsulated as an Ethernet message, and the corresponding LLID is attached and sent in the tree PON network. The optical splitter in the ODN broadcasts the data stream to each branch, and all ONUs can receive the downlink Ethernet data frame, and selectively receive their own data according to the LLID.
C.The EPON standard is one of many TDM-PON standards and has the basic characteristics of a TDM-PON network: a tree topology network is composed of OLT, ONU and ODN (Optical Distribution Network).
D.In the logical topology, the EPON protocol establishes a logical link for the OLT to each ONU, and the leading byte of the Ethernet data frame carries the logical link identity, that is, LLID (Logical Link Identity).

What are the incorrect statements about Type B protection for GPON networks?

A.Protection based on PON port and backbone fiber
B.Support OLT inter-board and intra-board port combination protection pair
C.Service configuration data only needs to be configured to the main port, no need to configure two copies
D.Switching trigger conditions: 1) branch fiber failure, 2) OLT single board failure, 3) component failure
