(single)Is the following description correct? The key parameters of the ODN network are attenuation, insertion loss, and return loss.
(single) Which layer of the OSI reference model does the Ethernet switch workon?
(single) Is the following description correct? ONT call emulation refers to the use of the ONT test module instead of the user's phone for call testing. When the ONT POTS user cannot provide voice services, the ONT call emulation test is performed remotely through the OLT command line to help the user diagnose whether the POTS user call of the ONT is normal. ONT can be offline when performing ONT call sim-ulation

(single) If there is multiple set-top boxes under one ONT (for example, HG850) while watching a multicast program, which of the following functions is enabled for the ONT multicast user on the OLT can ensure that one set-top box switches channels while other set-top boxes are watching. The program is not affected?
(multiple) In SNMP V1, which of the following messages is a communication message between the NMS and the Agent?
(single) Regarding the ADSL rate limit in the UA5000, which of the following statements is incorrect?
(single) In the GPON network, which of the following options must be bound to the MA5680T DBA template to take effect?
(multiple) Which of the following access network products can provide ADSL access?
(multiple) Regarding the QinQ VLAN, what are the following statements correct?
(multiple) The MA5600T supports multiple traffic classification technologies. What are the currently supported traffic classification technologies?
(single) Which index range does the MA5600 extended access control list have?
(single) Which of the following boards does not belong to the narrowband service board of the UA5000?
(single) Is thefollowing description correct? The MA5600T/MA5680T GPON Internet service simplification method optimizes the number of templates and complex configurations in the template mode, reducing user configuration workload and post-maintenance costs. The simplified mode currently only supports the GPON FTTH scenario. For the newly created GPON FTTH scenario and scenarios with low QoS requirements, the simplified mode can be used for service configuration.
(multiple) About MA5600 Super vlan and Sub Vlan, what are the correct descriptions below?
(single) Is the followingdescription correct? Triple play in the MA5600T supports the triple play mode of single PVC and the triple play mode of multiple PVCs for xDSL access mode.
(single) Is the following description correct? G.SHDSL broadband access technology is suitable for hotels, Internet cafes, high-speed Internet access, video conferencing, etc., but can not provide dedicated line interconnection and dedicated line access.
(single) Whatis the maximum number of ADSL2+ users in the MA5600 single frame?
(single) Is the following description correct? When creating an ADSL line configuration template, the MA5600T can specify the template number or not. If not specified, the system automatically assigns the smallest idle template number.
(single) 1518 byte Ethernet data packets are converted into ATM cells by 1483 b format encapsulation, how many ATM cells will be converted?
(multiple) Which of the following are commonly used positioning methods for Ethernet docking faults?
(single) Is the following description correct? The MA5600T/MA5680T supports VLAN tag conversion. When an SVLAN with different attributes creates a service flow through theservice-port, if the tag-transform is set to default, the Tag conversion rules are different.
(single) The following description of the MA5680T GPBD board, which is wrong?
(Single) The UA5000 narrowband main control board PVM and the broadband main control board IPM are connected to each other to provide voice services and broadband services. The voice service is transmittedto the IPM board through the internal IP channel, and then transmitted to the upper layer by the uplink interface of the IPM board. Network, which command should be used to configure the system networking mode?
(single) Is the following description correct? The larger the return loss, the better. In general, the return loss of APC is greater than that of PC type connector.
(single) Which method does the BTV service use to send messages on the network?
(single) The value of the PROTOCOL field of the PPP protocol is 8021. What is theprotocol represented?
(multiple) What are the following aspects of the total loss of the ODN link?
(single) Is the following description correct? The mounting ears of the MA5616 are used for 19-inch cabinet installation.
(single) Among the access technologies of the access network, which of the following access modes can provide the largest access bandwidth?
(single) Is the following description correct? VDSL2 provides uplink and downlink symmetric/asymmetric transmission rates on a pair of twisted pairs, with a transmission distance of about 3 km, a maximum downlink rate of 52 M (symmetric rate), and a maximum uplink rate of 12 M (asymmetric rate).
(single) Is the following description correct? When a multicast service is configured on the MA5680T, the unicast VLAN that carries the multicast service must be the same as the multicast VLAN.
