1. When the ADSL/ADSL2+ line conditions are better, what parameters can be adjusted to increase the transmission rate?

2. The essence of the GPON system carrying TDM signals is to encapsulate the TDM into GEM frames on the ONU, decapsulate the GEM frames into TDM signals on the OLT, and then transmit them to devices capable of TDM signals on the uplink.

3. Traffic suppression on the uplink port of MA5680T suppresses multicast only for unknown multicast traffic.

4. When locating ADSL/ADSL2+ faults, which of the following may cause users to make calls but not access the Internet?

5. After the VoIP user picks up the phone, he can hear the normal dial tone, but after dialing, the dial tone is not stopped. What are the possible reasons? (Multiple Choice)

6. All H.248 commands require the receiver to send back a response.
Which of the following is used to indicate the response message?

7. ADSL PPPoE/PPPoA users of the MA5600 implement authentication and access the Internet on the upper BRAS. After the opening, there is often a service interruption, but once the interruption is over, it is possible to redial the Internet again. This problem may be caused by incorrect configuration of the interleaving delay of the port parameters.

8. MA5600T/MA5680T supports Ethernet, E1, and POTS services on the PON side and does not support ATM services.

9. How many kinds of acceptance test project are classified by MA5600T Acceptance Test Manual? (Multiple Choice)

10. The alarm level of the MA5600T can be divided into five levels: critical, major, minor, warning, and cleared.

11. According to the IEEE 802.1Q standard, where is the VLAN identification field in the Ethernet frame?

12. By default, which type of the following should be the queue scheduling mode on the MA5600T/MA5680T?

13. The MSAN is connected to the lanswitch GE or FE, the working mode of the two ports, one can be self-negotiation mode and the other is mandatory mode.

14. If the MA5680T does not start properly (non-hardware problems, the system keeps restarting), usually we can use the BIOS upgrade method to end.
What kind of uploading method does the MA5680T load the package file when using the BIOS upgrade? (Multiple Choice)

15. In the template mode of the MA5680T, where should the integration of tcont and gemport be configured?

16. The minimum transmit rate in the ADSL/ADSL2+ parameter indicates the minimum transmit rate that must be reached in the direction after the line is activated. If the maximum is set too large, the modem cannot be activated normally.

17. After installing the sybase patch, which of the following commands can display the version information of the installed sybase patch?

18. What is the command to support local loopback on the MA5600 ADSL port?

19. In GPON Networking, which of the following does not belong to MDU series products?

20. When configuring multicast services, the VLAN carrying the multicast service must be the same as the unicast VLAN ID.
