Voice Option Testing
Option Module Test
It is only possible to fully test the voice module if the installation of the AC and the backhaul
connections to the switch are in place. Netspan also needs to be connected. The card is set
for 120ohm or 75ohm dependant on the type of backhaul selected on Netspan. When
connected to the AC using the correct impedance port the relevant LED should be green. A
red LED signifies link disconnection, and an amber LED signifies link present but faulty.
Check that the module responds to disconnection of a link. If a switch test is to be undertaken
the CT should be connected to a DACU and a voice call made from the DACU to the switch.
