A.The TE link is flooded to the entire network by the LMP protocol. Each intelligent network element saves the TE link information of the entire network.

B.The verification of the TE link occurs before the control channel is established between adjacent nodes.

C.The TE link path is a resource concept. It can be understood as an optical fiber with bandwidth information and protection attributes, but it does not correspond to the optical fiber. One fiber may correspond to multiple TE links.

D.The intelligent network element sends its own bandwidth and other information to other intelligent peers in the network through the LSA in the form of a trace. Provide teaching support for routing and planning.

A.First locate external and then location transmission

B.First advanced, then low level

C.First single wave, followed by multiple waves

D.First two-way, then one-way first

B.Configure QoS

C.Configure the UNI port

D.Configure port DCN

A.Automatic mode

B.Near-end mode

C.Manual mode

D.Intra-office mode

A.Set the lock or forced switch command

B.Waiting for the recovery time to be set too long
