Which of the following are prerequisites for self-healing networks?
A, C, D
Subnetwork connection protection (SNCP) requires the APS protocol.
B
When configuring 1+1 optical line protection, you can select RI1/TO1 or RI2/T02 as the working
channel according to the actual situation.
A
The working and protection ports of a linear MSP group must be on the same board.
B
When ODUk 5NCP is configured, common WDM services can be converted into SNCP services, but
SNCP services cannot be converted into common WDM services.
A
When an OTU board works with an OLP board, the optical power difference cannot be used as a
trigger condition for intra-board 1+1 protection switching.
A
Self-healing refers to the capability of a network to automatically recover its services within a short
period from a fault without any manual intervention. Users are unaware of the network fault. A
network with this self-healing capability is a self-healing network.
A
Two PIU or APIU boards of an OpCXtrans E6616/OptiX OSN 1800V Pro are used to supply power for
the system In hot backup mode. When either of the two PIU or APIU boards is faulty, the system can
still function properly.
A
Hitless protection switching (HPS) provides the dual fed and selective receiving function for fiber
differential protection services and aligns the end-to-end latencies of the working and protection
paths, improving service reliability.
A
The OTUCn signal rate does not include the FEC overhead area.
B
According to the formula "OTUk rate = 255/(239 - k) x STM-N frame rate", the OTU3 signal rate is
255/236 x STM-N frame rate.
A
The nominal rate of OTU4 signals is 111,809,973.568 kbit/s. Generally, the line rate is 112 Gbit/s.
A
In the OTN standard system, which of the following protocols defines optical transport network
interfaces?
B
Which of the following statements about OTN advantages is false?
D
Which of the following is the main networking type of a transmission network?
B
