Content Area

The frame on the right is the content area, and the gray bar above the content area shows the navigational path so you can quickly identify where you are at any time.

Typing and Selecting Information in Fields

To modify information in fields, use the mouse to highlight and delete existing information. Type in new information. Some fields offer drop-down menus from which you choose settings.

Validating Information in Fields

Some Cisco TelePresence System Administration windows contain Apply and Reset buttons, which are initially disabled. Once you change or add settings in these windows, both buttons become enabled.

• Use the Apply button to apply new or modified information. When you click Apply , validation is performed for all fields in that window, and a message is displayed if there is invalid data in the fields.
• Use the Reset button to discard changes and restore the values shown when the window was first displayed.

Other Cisco TelePresence System Administration windows have fields containing information such as IP addresses, domain names, media port numbers (view only), and so on, that are validated when you exit the field. When information in a field is found to be invalid, a message describing the error is displayed.

Note View only fields such as stop and start media port numbers can be configured by going to Devices > Device Settings > SIP Profile in the Cisco Unified CM Administration interface. See the Cisco Unified Communications Manager Configuration Guide for the Cisco TelePresence System on Cisco.com for more information.

Validating Information in Windows

When you go to the navigation pane and click a task, the Cisco TelePresence System Administration software checks data in the current window and takes an action, as follows:

• If all changes are saved, the content area displays the requested window.
• If there are unsaved changes in the current window and data is valid, a message reminds you that there are unsaved changes. An OK button saves the changes, and a Cancel button allows you to continue modifying data.
• If there are unsaved changes and the data is not valid, a message explains what to do and provides OK and Cancel buttons to assist you.

Note If you change settings and click Apply in the navigation pane, the request may take a few moments to take effect. Wait until the pending request is completed before clicking a new task.

Device Test

The Device Tests tab provides the traditional Hardware Setup troubleshooting tasks for the following Cisco TelePresence System peripherals:

• Devices
• Cameras
• Speakers
• Microphones
• Presentation Devices
• Other Devices

CTX Tests

The CTX Tests tab provides acoustic tests to determine the acoustic suitability of a room for the installation of a Cisco TelePresence system. You can perform the following acoustic tests:

• Reverberation
• Noise Level

Note 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 1-5 shows the CTX Tests window.

Figure 1-5 CTX Tests

Reverberation

The reverberation test measures how long it takes for sound waves in the room to decrease by 60 decibels.

When sound waves are generated in an enclosed environment, they continue to reflect from surface to surface until the energy is completely absorbed. This reflection of sound is called reverberation. Reverberation is measured as the rate of time in milliseconds (ms) for sound to decay by 60 decibels (RT60). Ideal conditions for human speech intelligibility are an RT60 value of 300 to 500 milliseconds for all frequencies between 125 Hz and 4 kHz. An extreme in either direction - too much reverberation or too little - can be detrimental to speech intelligibility, and since Cisco TelePresence is generally located in a meeting room in which the human voice is the main source of audio, an ideal sound-quality design preserves the human range of frequencies and isolates this range from interruptions.

For a more thorough discussion of room acoustics and reverberation, and the effect on telepresence conferencing, see the Cisco TelePresence Room Design Guide .

To perform a reverberation test:

Step 1 From left panel of the the CTS Administrative UI, select Troubleshooting > Hardware Setup.

Step 2 Select the CTX Tests tab.

Step 3 Select the Reverberation radio button.

Step 4 Click Start.

The reverberation test will take several minutes to complete. Once complete, the CTS will restart. During the time of the test, and while the CTS is restarting, you will not be able to make telepresence calls.

Note It is important that the room be as silent as possible during the test.

Note The CTS will produce loud tones during while running the test. Cisco recommends exiting the room while the test is running.

After the test is complete, the CTS Administrative UI will display the results of the test, showing the RT60 in milliseconds (ms) at various frequencies. A sample of the test output is below:

In the above example, a tone at 250 Hz had an RT60 of 360 ms, a tone played at 500 Hz had an RT60 of 450 ms, and so on. If the RT60 ranges for all of the measured frequencies fall between 300 ms and 500 ms, the reverberation in the room is ideal for a Cisco TelePresence system.

Noise Level

The noise level test measures the background noise present in the room. The noise level test measures background noise in decibels with A-weighting (dBA). The Cisco TelePresence system is designed to work in rooms with background noise levels of 45 dBA or lower. Background noise levels above 45 dBA begin to compete with the intelligibility of human speech, and these noises become distracting for participants. Background noise levels over 55 dBA can cause gating or soundsuppression effects in the Cisco TelePresence audio

For a more thorough discussion of room acoustics and noise levels, and the effect on telepresence conferencing, see the Cisco TelePresence Room Design Guide .

To perform a noise level test:

Step 1 From left panel of the the CTS Administrative UI, select Troubleshooting > Hardware Setup.

Step 2 Select the CTX Tests tab.

Step 3 Select the Noise Level radio button.

Step 4 Click Start.

The noise level test will take several minutes to complete. Once complete, the CTS will restart. During the time of the test, and while the CTS is restarting, you will not be able to make telepresence calls.

Note It is important that the room be as silent as possible during the test.

Note The CTS will produce loud tones during while running the test. Cisco recommends exiting the room while the test is running.

After the test is complete, the CTS Administrative UI will display the results of the test, showing the average ambient noise level in decibels, as well as the noise level in decibels at a range of frequencies. A sample of the test output is below:

In the above example, the average ambient noise was measured at 42.06 dBA (decibels), the ambient noise at 125 Hz was measured at 46.51 dBA, the noise level at 250 Hz was 41.47 dBA, and so on. An average measurement of 45 dBA or lower indicates that the noise levels in this room are acceptable for the installation of a Cisco TelePresence System.
