CTX Tests (Not Available on All Systems)
The CTX Tests tab provides the following troubleshooting tasks for the CTX:
•Reverberation
•Noise Level
Note Running a test will not end a call but may temporarily change what is shown on local and remote displays.
Because the test stops and then starts various services, if you decide to stop the test before it completes, it might take a few minutes before your system is usable. Do not perform any actions on the system while the test is running, and do not switch to another test while the test is running.
Figure 2-2 shows the CTX Tests window.
Figure 2-2 CTX Tests
Reverberation
During this test, the Cisco TelePresence System collects sound pressure levels and noise criteria for each frequency. Once the test is completed, the results are shown in the Test Results.
Tip Ensure that the room is silent while you perform these tests. Any external noise will interfere with the testing process.
Step 1 Select the Reverberation radio button and then click Start.
The system issues the following information:
"Test Running: Test is running. Please wait until the test completes; if you stop the test, no results will be recorded."
The test takes a few minutes to complete. When complete, system reverberation information is displayed in the Test Results window, as shown in Figure 2-3.
Figure 2-3 Reverberation Test Results
Step 2 If desired, click Download Log.
The system asks whether you want to open or save the .txt file. This completes the reverberation test.
Noise Level
During this test, the Cisco TelePresence System plays audio chirps and collects the average sound decays for each frequency. Once the test is completed, the results are shown in the text field.
Tip Ensure that the room is silent while you perform these tests. Any external noise will interfere with the testing process.
Step 1 Select the Noise Level radio button and then click Start.
The system asks you if you want to continue with the test.
Step 2 Click OK in the dialog to begin the test.
The system issues the following information:
"Test Running: Test is running. Please wait until the test completes; if you stop the test, no results will be recorded."
The test takes a few minutes to complete. When complete, system noise level information is displayed in the Test Results window, as shown in Figure 2-4. If you have already run a reverberation test, the noise level test will appear at the top of the window.
