Detection principle for GPON type B single-homing protection switching: The standby port received transmits optical signals. If the standby port fails to detect upstream optical signals for four consecutive dynamic bandwidth assignment (DBA) allocation periods, an upstream optical signal interruption occurs, triggering automatic protection switching.

If multiple users connected to the same PON port of the OLT go offline, the possible cause is:

If the configuration issued by an OLT to an ONU exceeds the capability of the ONU, the configuration status of the ONU changes to failed.

An IPTV user can go online normally, but no multicast program is played for a long time and the screen is black. The possible causes include.

A PC connector cannot be connected to an APC connector, but a PC connector can be connected to a UPC connector.

Which one of the following conditions does not trigger GPON type B single-homing protection switching?

DRAG DROP -
Please, drag the types of ports on the control board to the corresponding functions. (Score only when all the answers are correct.)

In the FTTB/C scenario, an ONU functions as an AG to connect to an IP phone. If the voice protocol is set to SIP, which of the following is a possible cause if no tone is played after a phone is picked?

When the coverage radius of the OLT is ( ), the comprehensive cost is optimal.

Which of the following statements about terminal selection principles are correct? (Choose all that apply.)

When planning VLANs, you need to consider: (Choose all that apply.)

Which of the following measures can be taken to control the GPON traffic? (Choose all that apply.)

The QoS should be planned according service requirements. Generally, a service with a higher priority adopts the ( ) scheduling mode.

Which of the following about the connection of fiber connectors are correct? (Choose all that apply.)

In a project, the maximum split ratio is 1:64. If three-level splitting is used, the split ratios are 1:2, 1:2, and 1:8 respectively.

Centralized splitting uses more optical cables, and distributed splitting uses more connection devices, such as fiber distribution boxes.

Which of the following statements about the connection of fiber connectors are incorrect? (Choose all that apply.)

Which of the following attributes is used by the NMS VLAN?

At present, people pay more and more attention to the network reliability, and have raised various reliability requirements on access devices, from single-node reliability to end-to-end reliability. These requirements include: (Choose all that apply.)

The passive optical LAN (POL) campus network architecture is the same as the traditional switching network architecture. Full-fiber access replaces the aggregation and access switches on the traditional switching network. OLTs function as the aggregation layer devices and are closer to core-layer devices. They can be deployed together with core-layer devices. ONUs functions as access layer devices and are closer to information points, enabling more flexible access to information points.

During DBA planning, which of the following types of DBA should be used if a user wants to apply for the Internet access service?

Which one of the following statements about NCE (Access Domain) HSI service configuration is incorrect?

On Network Cloud Engine (NCE), both manual dump and automatic dump allow you to dump the performance data that meets the criteria to a file on the local disk.

The eSight provides automatic discovery modes based on the network segment, ARP, and routing. In addition, you can create an exclusion list of network segments or IP addresses of devices that do not need to be connected. During automatic device discovery, the system automatically skips the network segments or IP addresses configured in the exclusion list.
