AC Impedance Test
SARVAM UCS supports the AC Impedance Test for clear, audible and echo-free speech over the CO Trunks. This
test helps you to set the most appropriate values for the CO Trunk parameters —AC Impedance, CO Termination
and CO Line Type— to correct the line impedance mismatch between the AC Termination Impedance presented by
the CO port of SARVAM UCS to the line and the CO Termination Impedance presented by the Central Office to the
line.
Conducting AC Impedance Test
You can conduct an AC Impedance Test,
• by making an outgoing call
or
• on an ongoing incoming call
To conduct the AC Impedance Test you will need,
• a telephone with a valid number. You are recommended to use - a mobile phone with Mute function.
• the CO Trunk which you want to test.
The DSS Key assigned to this CO Trunk will display status as busy to all the user, for the duration of the
test.
Configuring Using Jeeves
You can conduct the test after you have set the relevant test parameters. To do this,
• Login as System Engineer.
• Under Basic Settings, click CO Trunks. Select the desired CO Trunk.
