A. The protection configuration of each site on the ring network must be completed before starting the protocol

B. ODUk ring network protection is mainly applied to the ring network configuration of distributed services, and realizes the protection of multiple distributed services between all sites by occupying two different ODUk channels

C. Enhanced ODUk ring network protection does not need to set up a management node. If setting the management node has no effect on protection

D. Ordinary ODUk ring network protection does not need to set up a management node.

A. True

B. False

A. B1 is Bit Interleaved Parity-8 (BIP-8). This byte is used to monitor the regenerator part layer for bit errors

B. JO is the regenerator section trace byte. This byte is used to repeatedly send the segment access point identifier so that the receiving end can verify its continuous connection with the designated sending end

C. E1 and E2 are wired bytes. These bytes are used to provide voice channels for order line connections.

D. A1 and A2 are framing bytes. These bytes are used to separate STM-1 frames in the signal stream

A. OSS system (Operation Support System) refers to a software system that provides operators with functions such as communication equipment performance management, inventory management, business management, and fault management.

B. The U2000 supports multiple northbound interfaces such as SNMP, TL1, XML, and DCORBA, which can realize rapid integration with the operator's OSS system.

C. The OSS system is mainly used to improve the work efficiency of equipment maintenance personnel

D. The network layer of the OSS is above the NMS, and the management of network element devices is generally implemented through the NMS.

A. Hardware Loopback

B. Soft reset service board

C. Software Loopback

D. Hard reset service board

A. Reflect the performance of network equipment, usually not compared with bit forwarding equipment

B. The first bit of the data frame appears at the output port and ends the timing

C. The last bit of the data frame enters the device to start timing

D. The first bit of the data frame enters the device to start timing

A. True

B. False

A. Enhanced 40-wave multiplexer/demultiplexer board

B. The board supports online optical power monitoring

C. Single board supports application in dual-fiber bidirectional system
