An IPTV user reported that they could not receive television signals. Upon turning on the debugging switch on the OLT side, the following debugging information was printed: huawei (config). The query results indicate that ().
- A . Insufficient PON port multicast bandwidth
- B . The user does not have permission to watch the program.
- C . IGMP Sakamoto mismatch
- D . User bandwidth verification failed.
By default, when DHCP Option 82 is globally enabled only on the OLT device, the OLT’s handling of received DHCP messages will change. Which of the following descriptions is correct?
- A . When receiving a DHC message from the user side, if it carries Option 82, the OLT will strip the Option 82 information from the message and add the local user information.
- B . When receiving a DHCP message from the network side, if it carries Option 82, OLT will forward it directly.
- C . When a DHCP message is received from the user side, the OLT will capture the message and add local user information.
- D . When receiving a DHCP message from the network side, if it does not carry Option 82, the OLT will add local user information.
The SIP protocol is an asymmetric protocol, and all actions of a SIP phone require control commands to be issued by the SIP server.
- A . True
- B . False
The simplest ODN networking method is to directly connect the OLT to the optical splitter, and then directly connect the optical splitter to the ONU.
- A . True
- B . False
Enabling the fast-leave feature for multicast users can provide a better user experience when switching channels.
- A . True
- B . False
Which of the following descriptions of the key technologies of XGS-PO]N is incorrect? (Multiple choice)
- A . The dynamic threshold adjustment function allows the OLT to adjust the value at once when it receives an optical signal to ensure signal integrity.
- B . To avoid potential data collisions during uplink data transmission, the OLT will activate the ranging function to allocate equalized latency to 0 when the ONU registers for the first time, and will maintain this parameter value thereafter.
- C . To ensure data security, XGS-PON supports the use of the A-SuperS encryption algorithm to encrypt the entire transmitted message.
- D . To avoid signal superposition and distortion, the OLT-side optical module needs to have burst transmission capability.
