Port Select the port whose MLT statistics you wish to see from the
list. Ensure that this Port number matches the Port number
in the upper part of this screen to view the results of a test
you just performed. When you switch between ports, click the
Refresh button to update the information to that of the new
port.
Test Item This section shows the statistics derived from the last test
performed on this port.
AC Voltage (Vrms) This is the port’s alternating current shown in volts root mean
square (Vrms)
DC Voltage (Volts) This is the port’s direct current voltage shown in volts.
Loop Resistance (Ohms) This is the port’s load resistance (between TIP and RING)
shown in Ohms.
Isolation Resistance
(Ohms)
This is the port’s isolation resistance shown in Ohms.
Capacitor (µF) This is the port’s capacitance shown in millifarads.
Ring Voltage (Vrms) This is the port’s ring voltage shown in volts root mean
square.
Metering Voltage (Vpeak) This is the port’s metering peak voltage.
REN Value This is the port’s ringer equivalent number.
Test Result This section shows the result of the test or tests you
performed.
Refresh Click this to reload the information in the Test Result
section. Do this when you change the Port number to see the
statistics for the new port.
