According to the Huawei official documentation, a gNodeB supports up to 4 OM channels at most. These channels can be used to monitor and manage the gNodeB remotely. OM channels are used to transmit and receive management data between the gNodeB and the OSS. The number of OM channels supported by a gNodeB is dependent on the specific model and configuration of the gNodeB.
Question 2
Which of the following actions will trigger SgNB release by the MeNB?
Options:
A.
The UE inactivity timer on the NR side expires.
B.
An inter-SgNB cell change occurs.
C.
The MeNB detects that the X2 link is abnormal.
D.
The air interface link on the NR side is abnormal, and a UE reports SCG Failure Info to the eNodeB.
Answer:
A, D
Explanation:
Explanation:
The UE inactivity timer on the NR side expiring and the air interface link on the NR side being abnormal, and a UE reporting SCG Failure Info to the eNodeB, can both trigger the MeNB to release the SgNB. Other actions, such as an inter-SgNB cell change or the MeNB detecting an abnormal X2 link, may also lead to SgNB release, but are not the trigger for it.

Question 3
In IEEE 1588V2 frequency synchronization, all intermediate transmission devices must support the IEEE 1588V2 protocol.
Options:
A.
True
B.
False
Answer:
A
Explanation:
Explanation:
In IEEE 1588V2 frequency synchronization, all intermediate transmission devices must support the IEEE 1588V2 protocol. This means that all devices that are involved in transmitting the synchronization signal, such as routers and switches, must be able to process and pass on the IEEE 1588V2 messages. If any device in the path of the synchronization signal does not support the IEEE 1588V2 protocol, it will not be able to process and forward the messages, and the overall synchronization will be affected.
