Question #47

Which of the following descriptions are correct in daily maintenance?

A. Unplug and plug the board with the customer's consent

B. During the cutover process, it is found that other unrelated network elements report an alarm, but the customer does not know that it will be processed directly

C. Without the authorization of the customer, the network management performs configuration data operations

Question #48

When planning AM, you need to consider the priority planning of E1. Which of the following options are the planning principles of E1 priority (multiple choice)

A. The priority of the E1 service has nothing to do with the time slot number of the IF board it occupies, but the priority is specified when the cross-connection of the E1 service is configured. There are two types of E1 priority: high and low.

B. The E1 priority function is mainly used in the scenario of Hybrid microwave transmission IMA service. At this time, the guaranteed E1 capacity should be equal to the E1 capacity required by IMA to transmit high-priority services; the full-capacity E1 capacity should be equal to the E1 capacity used by IMA.

C. The priority set when an E1 service passes through a multi-hop microwave link can be different.

D. When the E1 priority function is enabled, E1 service bandwidth under full capacity ≤ full capacity service bandwidth-guaranteed capacity service bandwidth + E1 service bandwidth under guaranteed capacity.
