B. Disable the OSI protocol on the three gateway NEs.

C. Disable DCC access on the three gateway NEs.

D. Delete the DCC transparent transmission bytes on the three gateway NEs.

Which of the following are false about software installation on the PC that runs the NMS?

A. Ensure that anti-virus software is installed on the PC.

SDH equipment supports many protection types. Which of the following statements is false?

A. It is recommended that the working board be removed for a TPS test two minutes after TPS protection is configured, because it takes a period of time for the protocol to obtain the physical type of the processing board.

B. When 1+1 protection is configured for the power supply, each PIU board provides 50% of the required DC power. When one PIU board fails, the other also stops providing power.

C. The 1+1 protection switching between GSCC boards is non-revertive. Services can be switched back only by removing the working board or issuing a switching command on the U2000.

D. After you insert a GSCC board back, the working GSCC board needs to synchronize data to the newly inserted GSCC board. Wait 5 to 10 minutes until the synchronization is completed. Then restore board active/standby status.
