A school uses POL with GPIOI access. Initially, due to low bandwidth requirements for each CNU, a 1:22 optical splitter was used to connect 32 information terminals. The customer plans to upgrade the bandwidth of the information terminals, doubling the concurrent bandwidth of each ONU. Which of the following operations are correct for this network upgrade? (Multiple choice)
- A . For this type of expansion scenario, it is recommended to reserve sufficient fiber optic resources from the OLT to the optical splitter in the early stages of project construction to avoid rewiring and termination during expansion.
- B . On the OLT, corresponding service flows must be added and removed for the migrated information terminals.
- C . Expand the PON board on the OLT, or use an unused PO port to connect a newly deployed optical splitter.
- D . Add a 1:16 optical splitter at the location of the original 1:32 optical splitter, and migrate the 16 information terminals on the original 1:32 optical splitter to the new 1:16 optical splitter.
- E . The original 1:32 optical splitter can no longer be used and should be replaced with two 1:16 optical splitters.
Under the H.248 protocol, when a local digitmap is configured using the local-digitmap add command, the MG device will prioritize matching the local digitmap when receiving numbers. If the matching fails, it will continue to match the digitmap issued by the MGC.
- A . TRUE
- B . FALSE
Poor voice call quality (noise, intermittent playback, or echo) C what are some of the possible reasons? (Multiple choice)
- A . Voice gain setting error
- B . Phone malfunction
- C . Grounding fault
- D . User loop fault
Which of the following options is incorrect?
- A . Jitter is caused by unequal end-to-end latency for each data packet.
- B . Packet loss rate is the percentage of packets lost during network transmission.
- C . Latency refers to the time it takes for information to be sent from one network node to another.
- D . After receiving a resource request from an application, a differentiated services model network needs to reserve resources for each information flow.
Which of the following statements about 10G EPON is correct? (Multiple choice)
- A . 10G EPON and EPON frame protocols are compatible.
- B . 10G EPON/EPON compatibility, that is, 10G EPON ONNU can coexist with 1G EPON ONU in the same ODNT.
- C . 10G EPON technology complies with the IEEE 802.3av standard, supports asymmetric transmission rates of 10Gbit/s downlink and 2.5Gbit/s uplink, meeting the needs of high-bandwidth services.
- D . The MPCP protocol of 10G EPON is completely the same as the IPCP protocol of EPON.
For SIART type VLANs, by default, Layer 2 communication is not possible between virtual ports of the same VLAN service.
- A . True
- B . False
What metrics are included in the QoS of a GPON system? (Multiple choice)
- A . Packet loss rate
- B . Bandwidth
- C . Shaking
- D . Delay
Enabling the anti-ipattack function on the OLT will prevent the device from being remotely managed via telnet.
- A . True
- B . False
Which of the following products are information access points in a POL ODN network? (Multiple choice)
- A . FDT
- B . ATB
- C . FMC
- D . CTB
