Test Descriptions

TEST_19 - RXA FVC Order Message Error Rate

Description

This test simulates a Forward Voice Channel (FVC) order message

being sent from a cell site to the cellular radio and measures the Order

Message Error Rate.

The test works as follows:

• A Forward Voice Channel (FVC) audit message is sent 100 times and

the number of acknowledgments from the MSUT is counted.

• The RF level is set by parameter 25. RXA FVC Message Error Rate

RF Level (dBm).

• If the MSUT misses 10 acknowledgments in a row the test

terminates.

FVC order message error rate is expressed in %.

This test is not specified by TIA/EIA standards.
