4 Test methods
4.1 Equipment
4.1.1 General
See 5.1.1 of GB/T 31723.405-2015 and Figure 1 of this part.
For the jumper test, two test sockets for the hardware module and extension cable are required to measure the jumper (see 4.1.3). These two tests
The ports are called the near-end test port and the far-end test port.
