A.Directioned scenes are applied to networks that are not ASON.

B.If the current path needs to be adjusted, you must inbound to adjust the fiber connection of the network.

C.The wavelength carrying the local service can be transmitted to fixed direction.

D.When the service needs to be adjusted, or the working path is faulty, the optical crossover can be manually configured to implement flexible scheduling of services.

A.If there are multiple clock sources with the highest quality level, the network element selects the clock with the highest clock priority as the synchronization source.

B.The network element broadcasts the clock quality information and the clock source ID of the synchronization source to the downlink site through the S1 byte, and reverse notices the uplink site that the clock quality from the local network element is "not available for synchronization" by the S1 byte in the direction of the synchronization source.

C.According to the clock source priority table, the network element first selects the clock with the highest quality level from the available clock sources as the synchronization source.

D.The network element broadcasts the clock quality information of the synchronization source to the downlink site through the s1 byte. And reverse notice the uplink site by the S1 byte in the direction of the synchronization source that the clock quality from the local network element is "not available for synchronization".

A.U2000

B.Anti-static gloves

C.Fiber extractor

D.Shielding bag

A.L is in standard Ethernet frame length with a minimum value of 64Bytes

B.M is the frame gap, and the minimum IFG (minimum frame gap) is 8 bytes.

C.Rate indicates the line rate of the physical layer. If the device port is FE, then Rate=100Mbit/s.

D."8" outside the brackets is 1 Byte containing 8 Bits
