Abstract:
1. A telecommunication port testing apparatus comprising: a first power interface; two first telecommunication ports; a first impedance stabilization network (ISN) comprising an input, an output, and a signal detecting pin; a first impedance matching network, wherein the first power interface is connected to the input of the first ISN through the first impedance matching network and one of the two first telecommunication ports in that order; a second impedance matching network, wherein the output of the first ISN is grounded through the other one of the two first telecommunication ports and the second impedance matching network in that order; a second ISN comprising an input, an output, and a signal detecting pin; a first switch; a second switch; and two second telecommunication ports respectively connected to the input and the output of the second ISN, wherein the first switch is operable to switch the first impedance matching network to selectively connect to the corresponding first and second telecommunication ports, the second switch is operable to switch the second impedance matching network to selectively connect to the corresponding first and second telecommunication ports.
