Each ONU has a concurrent upstream and downstream bandwidth of 150Mbps/300Mbps. Excluding splitting loss, the maximum link loss is 10dB. What splitting ratio should the optical splitter use in this project?
- A . 1:32
- B . 1:16
- C . 1:4
- D . 1:8
When PITP is enabled globally or in a VLAN service template on the OLT, and the service virtual port allows upstream packets to carry vendor tags, and user upstream packets carry vendor tag information, which of the following statements about the OLT’s PITP packet processing strategy is correct?
- A . OLT adds the local vendor tap to the upstream PITP message
- B . OLT directly forwards the user-side PITP message without any processing
- C . The OLT strips the vendor tag carried in the upstream PITP message and adds the local vendor tag
- D . The OLT discards the upstream PITP message
In the FTTB/C scenario, the ONU is connected to the phone as an AG device. The possible reason for the failure of no sound when picking up the phone during SIP protocol is ().
- A . Packet loss occurs in the OLT upper layer network
- B . The ONU (MG) interface status is abnormal
- C . Voice server failure
- D . ONU and IMS are unreachable.
For the message priority processing of the outgoing port, mapping or direct setting can be adopted.
Which of the following options correctly describes how priorities are handled?
- A . Regardless of how the priority is set, the corresponding priority strategy must be tag-in-package.
- B . There is a strict one-to-one correspondence between the priority mapping of outgoing and incoming packets. The outer VLAN cannot map the priority of the inner VLAN.
- C . Priority mapping can be set separately for inner and outer priorities.
- D . Priority mapping needs to match the corresponding mapping template, and the mapping relationship within the template is fixed.
