A.OSC board must be configured in the network

B.An OA board must be configured between the FIU board at the receiving site of the OMS segment and the ROADM board or the split/multiplexer board

C.Optical amplifier boards of the same dimension can be inserted into different network elements

D.The outbound optical amplifier at the originating end of the OMS segment must be configured with an MCA board

A.The IP address of U2000 is 129.9.0.100/24, and the IP address of the gateway NE it manages is 129.9.0.2/24. If the U2000 wants to communicate with a network element with an IP address of 133.168.0.2/24 that is connected to a gateway network element through IP over DCC, the U2000 needs to be directly connected to the gateway network element.

B.Huawei transport domain network elements all support the HWECC protocol, and the default physical transmission channel is D1 to D12 bytes. When the network element ID is set, the ECC communication can be carried out without any configuration after plugging in the optical fiber.

C.Huawei transport domain network elements support three communication protocols for DCN networking, among which the HWECC protocol is a private communication protocol developed by Huawei for DCN networking of transport domain network elements.

D.The network management server and each managed network element adopt in-band networking or out-of-band networking for communication. In-band networking refers to the networking mode in which the U2000 uses the service channels provided by the managed devices to manage the devices in the network.

A.PE only needs to determine the forwarding of the Ethernet frame based on the VLAN ID in the user message without other parameters (such as the destination MAC address in the message, etc.), whether it is forwarded directly to the CE or to the PW through the PW Peer PE

B.VSI is a virtual layer 2 forwarding entity, which defines the number of members of the VPLS domain on the PE, similar to a virtual switch

C.VPLS (Virtual Private LAN Services), is a kind of service similar to LAN provided on MPLS (Multiprotocol Label Switching) network

D.Need to manually configure the split horizon group to avoid the loop of Full-mesh VPLS

A.During the commissioning period, the weather conditions are good, and there is no rain/snow/fog impact between the two sites

B.Turn on AM function

C.If the microwave link adopts a 1+1 protection configuration and uses one antenna, turn off the power of the backup ODU before switching the antenna

D.ATPC function is off
