What is the method used to multiplex low-order ODUx signals into high-order ODUk signals?
- A . Wavelength Division Multiplexing
- B . Frequency Division Multiplexing
- C . Time Division Multiplexing
- D . Space Division Multiplexing
What are the reasons why the ODUk_PM_OCl alarm statement is correct? (Multiple choice)
- A . The board corresponding to the upstream site has an ODUk_PM_OCl alarm
- B . The corresponding board of the peer station is set up with loopback
- C . The corresponding board of the opposite micro station is not configured with cross-connection and the non-intrusive monitoring function is enabled on this end.
- D . This alarm will cause the service carried by the optical interface to be interrupted
Which of the following statements about OTN multiplexing and overhead is wrong?
- A . Client signals (e.g., IP/MPLS, Ethernet, SDH signals) are mapped to ODUk as ODU payload plus ODU overhead.
- B . ODUk is combined with OTU overhead and FEC overhead and mapped to the standardized optical channel transmission unit, which constitutes OTUk
- C . OTN optical layer overhead is non-channel overhead and is transmitted by an independent optical supervisory channel OSC.
- D . The overhead of the OTN electrical layer unit is the channel overhead, which is transmitted together with the payload.
NG-SDH data boards can expand their functions through software upgrades
- A . True
- B . False
Mapping is the process of adapting branch signals into () at the boundary of the SDH network.
If the site location is appropriate, ROADM sites and OTM sites composed of M4OV/D40 back-to-back can play the role of OEQ sites for pass-through wavelengths.
- A . True
- B . False
Which of the following statements about traffic regulation and traffic shaping is correct?
- A . Traffic policing can only be used in the inbound direction, and traffic shaping can only be used in the outbound direction.
- B . Traffic policing can only be used in the outbound direction, and traffic shaping can only be used in the inbound direction.
- C . Traffic policing can be used in both inbound and outbound directions, while traffic shaping can only be used in the outbound direction.
- D . Traffic policing can be used in both outbound and inbound directions, while traffic shaping can only be used in the inbound direction
An intelligent clock subnet can realize automatic tracking and automatic switching of clocks by simply configuring the reference clock, thus avoiding clock interlocking.
- A . True
- B . False
In an ASON network, if the control channel between two network elements is blocked, which of the following options is impossible?
- A . The logical board of the network element is not created or is created wrongly.
- B . The other end does not have the intelligent feature enabled
- C . DCC between two network elements is not working
- D . The DCC byte is not allocated to the corresponding resources of the 9-byte mode
For Huawei equipment, NODE ID is the unique identifier of the intelligent network element in the control plane. After the network is configured with intelligent services, the NODE ID will no longer be modified.
- A . True
- B . False
