5: Network packet capture function

Connect the two RJ45 interfaces of the device in series, with one end connected to the upper end device of the network
and the other end connected to the lower end device of the network. Realize the capture of data content, including but not
limited to: link layer, network layer, transport layer, and application layer data.
Data can be continuously captured through embedded packet capture software or devices, and the saved formats of the
obtained data packets include but are not limited to PCAP format. The data packets can be fully exported through the
terminal for analysis.

6: TV simulation function

By connecting the HDMI interface of the device to the HDMI video cable of the set-top box, the HDMI signal output from the
set-top box can be received. After automatic recognition and analysis of the video source resolution, the device plays and
displays the sound and video content through the terminal.

7: Video troubleshooting function

By connecting the two RJ45 interfaces of the device in series, one end is connected to the video network port of the upper
ONU, and the other end is connected to the network port of the lower set-top box. The proprietary IPTV troubleshooting
analysis function software can be launched to analyze the IPTV network protocol and network configuration, including the
transmission protocol encapsulation format Source Mac 、Dest Mac 、Vlan priority 、IP Tos 、IP ttl 、Source IP 、DestIp 、
Source Port 、Dest Port、Rtp Type. Support service data transmission quality testing, with testing indicators including IP
packet quantity, business data transmission rate, jitter, packet loss, etc.

8: Remote control function

The device has the function of remote control of VFL and OPM, and can use WeChat mini-program to remotely control the
VFL switch, making it convenient to directly conduct relevant tests remotely.

9: Dial test function

Equipped with a dial test function, the device can be placed at the user’s home as a testing probe when there are
intermittent network issues or specific time periods of problems. Speed measurement tasks can be created, and the serial
number of the testing equipment can be entered manually or by barcode scanning. The number of tests and testing
intervals can be set, and the data to be tested for dial testing can be selected, including basic device information (MAC,serial number, chip brand, memory, RAM, terminal brand model, etc.), device status information (CPU status, battery
status, device temperature, runtime, network layer information, etc.), connected WIFI information, surrounding WIFI
information, ifconfig information, ping test information, traceteute test information, speed measurement information, etc.
Test records can be viewed.:
