1 Amplifier—When set to ON (enabled), the DS3 signal at the test port TX connection(s) is amplified to a
(nominal) 0db DSX level during monitor access modes. For use only when the external DS3 test equipment
requires DSX level signals (cannot receive monitor level). Please check your test equipment specifications to
determine the appropriate settings.
2 Termination Resistor—When set to ON (enabled), a line termination resistor is internally connected to the
test port TX connection(s) during split access modes. For use only when the external test equipment does not
provide line termination.
