Type This field applies when you select the Ring Voltage, Pulse and DTMF Digit, or All MLT
tests.
If you selected All tests, use 0 to perform all tests or 1 to test AC voltage, DC voltage,
isolation resistance, and capacitance.
If you selected the Ring Voltage test, use 0 to have the system automatically start and
stop ringing or use 1 to manually start the ringing and 2 to manually stop the ringing.
If you selected the Pulse and DTMF Digit test, use 0 for automatic testing or 1 for
manual testing. With 1, use the Count field to specify how many manual inputs are
required to finish the test.
Count When performing the Pulse and DTMF Digit test with Type set to 1 (manual testing),
select the number of manual inputs required to finish the test.
All Perform all the MLT tests.
AC Voltage Test the line’s AC voltage.
DC Voltage Test the line’s DC voltage.
Load
Resistance
Test the line’s load resistance.
Isolation
