Contents

You may want to periodically test system components using the hardware and software tests available in the Cisco TelePresence System (CTS) Administration Troubleshooting window. This chapter contains information about troubleshooting TX1310 65 hardware and software.

Before You Begin

1. Obtain your IP address:

From the Cisco TelePresence Touch 12 tap the following:

More > Status > System Status

2. Make a note of the IP address.

3. Enter the IP address in your laptop’s browser window.

4. Click Yes to accept all security connection messages.


Note You cannot perform diagnostics during an active Cisco TelePresence system call.


Proceed to the following sections to troubleshoot system components:

Managing TX1310 65 Hardware Setup

You can manage and test the following Cisco TelePresence System components:

Before You Begin

Before you begin testing and troubleshooting your system, check the system displays. All of the Cisco TelePresence System Administration interface Hardware Setup features require the use of the displays in the meeting room. Therefore, we recommend the following:

1. Verify that the displays work by using the Hardware Setup > Displays tests in this section.

2. If the displays are showing the correct images, you can proceed to testing the cameras, speakers, and microphones, as needed.


Note You must test the speakers before testing the microphones because the microphone test depends on speakers that are functioning properly. See the “Testing Speakers” section.


 


Note CTS initial setup is also performed using the Hardware Setup fields. For information on how to configure CTS for the first time, see the Cisco TelePresence System TX1310 65 Assembly, Use & Care, and Field Replacement Unit Guide.


Configuring the TX1310 65 Table

Before you can set up the cameras in a Cisco TelePresence System TX1310 65 (TX1310 65) conference room, the Cisco TelePresence System (CTS) software needs to know the size and shape of the table in the room. A drop-down menu is provided that allows you to specify the shape of the table in the room and where participants will be seated.


Note The TX1310 65 is designed to be used in any type of multipurpose room. However, to ensure that you have the best conferencing experience, Cisco recommends that you optimize your room by using the guidelines and recommendations in Cisco TelePresence System TX1310 65 Room Recommendations chapter in the Cisco TelePresence System TX1310 65 Assembly, First-Time Setup, and Field-Replaceable Unit Guide.


Specifying the Table Size and Shape

Figure 1-1 shows the TX1310 65 table configuration menu.


Note You must specify the table shape before you can perform camera and microphone testing on the TX1310 65.


Figure 1-1 Cisco TX1310 65 Table Configuration Menu

 

 


Note If you log out of the Cisco TelePresence System Administration interface at any time during the camera testing procedure, you must re-select the table type.


For information about configuring the TX1310 65 table type, refer to the “ Configuring the TX1310 65 for Use With a Rectangular or Racetrack Table” section in the First-Time Setup chapter of the Cisco TelePresence TX1310 65 Assembly, Use & Care, and Field-Replacement Unit Guide.


 

Managing Displays

A display is set up successfully when the color on the display has been adjusted for the lighting in the meeting room.


Note Each display must be adjusted individually.


Use the information in the following sections to adjust the display for your system:

Selecting the Light Level

When adjusting the images on the CTS display screens, you must take the color temperature of the ambient light in the room into consideration.

Sources of light in most rooms are produced by fluorescent fixtures or incandescent light bulbs that use tungsten filaments. Each of these light sources, and the amount of light in terms of lumens or watts, produces a different color temperature. This color temperature is sometimes expressed using terms such cool , warm , or daylight , but can be expressed more precisely in kelvins (K) as a numeric value.

The following temperatures can be selected for adjusting the image on the Cisco TelePresence display screens:

  • 3500 K
  • 4000/4100 K (recommended)
  • 5000 K
  • 6500 K
  • 7500 K

Tip In many cases, the color temperature is printed on the light bulb. If you are unable to ascertain the type and color temperature of light bulbs in the meeting room, experiment with color temperature settings until the color and images on the display screen look lifelike.



Tip It is OK to try a few different color temperatures to see what looks best in the room. Remember, the Color Temperature setting only effects how the local participants see the display, it does not effect the way the room looks to remote participants.


Proceed to Adjusting Your Display.

Adjusting Your Display

To adjust a display:


Step 1 Log in to the Cisco TelePresence System Administration interface.

Step 2 Choose Troubleshooting > Hardware Setup.

Step 3 Click the Displays radio button. A test image appears on the screen.

Step 4 Click Start in the Testing box to start the adjustment process.The Current Color Temperature test screen appears, as shown in Figure 1-2.


Note Each display in the meeting room should be showing a set of horizontal grey bars and that display's relative position. The current color temperature setting is displayed.


Figure 1-2 Color Temperature Test Screen

 

 

Step 5 Select the color temperature of the lighting in the meeting room from the drop-down menu. The Apply button is activated.

Step 6 Click Apply .

Step 7 Click Stop to stop the test.

For information about configuring the TX1310 65 table type, refer to the “ Configuring the TX1310 65 for Use With a Rectangular or Racetrack Table” section in the First-Time Setup chapter of the Cisco TelePresence TX1310 65 Assembly, Use & Care, and Field-Replacement Unit Guide.

Saving Your Settings

When you have configured all your settings:


Step 1 Click Apply to register new or modified settings.

Step 2 Click Reset to restore the original settings.

For more information about testing and troubleshooting the TX1310 65, see the Setting Up the Camera section in the First-Time Setup chapter of the Cisco TelePresence TX1310 65 Assembly, Use & Care, and Field-Replacement Unit Guide.


 

Arranging the Seat Alignment Guides

Conference participants should be seated in an area that is completely within the field of view of one of the three cameras. To ensure this requirement, Cisco provides you with Seat Alignment Guides. After you set up the cameras, you place these guides on the table; these guides show the field of view for each camera.

To place the seat alignment guides on the table, complete the following steps:


Step 1 Using a supported Internet browser, log in to the Cisco TelePresence System administration GUI.

Step 2 Select the correct table type by completing the following steps:

Step 3 Navigate to Troubleshooting > Hardware Setup > Cameras .

Step 4 Click Start to display the image of the cameras in the displays.

Step 5 Note the field of view for each camera.

Step 6 Using non-marking tape (for example, masking tape), tape a mark on the table that denotes the edge of the field of view for each camera.

Place this mark approximately 18 inches (46 cm) from the edge of the table, and point the line of tape at the camera.


Tip If you cannot determine the camera range, use this guide for marking the table: The focal range of the center segment is approximately 5 feet (152 cm) wide from where the participants sit. The focal range of each side segment is approximately 4 feet 6 inches (137 cm) wide.


Mark the table in four places:

  • Edge of camera view, left camera
  • Edge of view between left and center camera
  • Edge of view between center and right camera
  • Edge of camera view, right camera

Note If your table is narrow, omit the two markings on the outer edges.


Figure 1-5 Measuring and Installing the Seat Alignment Guides

 

Step 7 Place another piece of tape 18 inches (46 cm) from the edge of the table where the participants sit to form a tape cross on the table.

Step 8 Remove the seat alignment guides and (if required) anchors from their packaging in carton 14.

Step 9 Place the seat alignment guides on each of the crosses on the table. See Figure 1-5 for more information.

Step 10 Arrange the seat alignment guides so that the line on top of the guides point directly toward the camera.

Step 11 Fasten the guides to the table using one of the following methods:

  • Remove the adhesive backing from the underside of the guide and stick it to the table, making sure that the line on the guide points directly at the camera.
  • Attach the seat alignment guide anchor to the table, and place the guide on the anchor, by completing the following steps:

a. Using a 1/4-inch drill bit, drill a 1.125 inch deep hole into the center of each tape cross.

b. Remove the tape.

c. Screw the seat alignment guide anchor into the hole that you drilled, using the key that is included with the anchor.

d. Place the seat alignment guide on top of the anchor.

e. Rotate the anchor until the line on top of the seat alignment guide points directly at the camera.


 

Understanding Camera Setup Choices for Room Lighting

If your room has windows that contribute a significant amount of natural light, you can set your CTS to automatically compensate for variable lighting conditions. This compensation is an average adjustment and will not be as accurate as the color settings you select for a room that uses fixed, artificial room lighting.

Table 1-2 contains recommendations for desirable display and camera settings when you set up the display and camera. See the “Testing the TX1310 65 Cameras” section for more information.

  • Check that the red and black pronged ends of the speaker cable are securely fastened under their corresponding connectors on the speaker.
  • Check that the speaker cable is plugged into the correct receptor on the primary codec.
  • Tug on the plug to see if it is fully plugged in. Push the plug in firmly until a click is heard.

Sound heard at wrong speaker.

Speaker cable is not connected in the correct connector.

Check that the speaker cable is plugged into the correct receptor on the primary codec. Plug all speakers into the primary codec.

Sound is not synchronized with video.

Contact Cisco technical support.

Choppy audio during double-talk (when both sides are talking simultaneously).

Audio Echo Canceller (AEC) very briefly mistakes one of the speech patterns for noise and cancels it, resulting in choppy audio.

  • The audio from the remote side is slightly attenuated before it is played out the of the speaker.
  • The echo cancellation feature removes some of the sound from the talkers during the double talk.

Check whether there has been a change in the echo path (someone has moved the speaker or microphone, or maybe a laptop directly in front of a mic). Otherwise, this is expected behavior. The existing filter parameters should be enough to cancel out the sound from the speaker. However, during double-talk, echo cancellation will always remove some sound from the talker.

For more information about setting up and testing speakers, see the Cisco TelePresence System TX1310 65 Assembly, Use & Care, and Field Replacement Unit Guide.

For more system troubleshooting information, see the Cisco TelePresence System Troubleshooting Guide on Cisco.com.

Testing Microphones

The microphones are set up successfully when each microphone registers sound. You must supply sound at each microphone to complete this test.


Note The number of audio meters that are shown on the test screen is determined by the number of microphones that have been configured in Unified CM and the version of Unified CM that you are running.


The Microphone Troubleshooting screen displays the number of microphones available for testing:

  • TX1310 65—3 “fixed” table-top microphones, 3 “positional” microphones that are mounted behind the top front cover above the display screen: left, right, and center. These microphones establish where the person who is speaking is seated to determine voice-activated camera switching.

By default, Cisco TelePresence uses 3 microphones for a conference that uses video. If you install more than three microphones, Cisco TelePresence uses those microphones for audio conferences only. Each microphone has a corresponding number of audio meters displayed on a single test screen. You can install up to 6 microphones on a TX1310 65.

Testing Microphones

Go to the following sections to test microphones:

Testing Microphones on the TX1310 65

To test microphones on the TX1310 65:

Note The room must be completely quiet to calibrate microphones. You may want to leave the room and close the door to carry out the calibration process to ensure complete silence in the room.


Each display in the meeting room should show an audio meter showing the audio level being picked up by that display's microphone.

  • The center display should show three microphones. A microphone that is not connected has a red slash.
  • The left and right displays should show three microphones unless the room is configured for seven microphones. If microphones at the far left or right are connected, they appear on the display with a yellow question mark.

Step 7 Click Ok to proceed with the calibration.

Step 8 Test each microphone by tapping gently with one finger.

Step 9 Click Stop to end the test.


 

Configuring Additional Microphones for Audio-Only Conferences

Cisco TelePresence uses three microphones for a conference that uses video. You can configure up to three additional microphones to use during audio-only conferences. Cisco TelePresence uses these additional microphones for audio conferences only.

To configure additional microphones for audio-only conferences, complete the following tasks:


Step 1 Connect the microphones normally to the audio/video extension unit.

You can connect one to three additional microphones (four to six microphones total).

Step 2 Log in to the Cisco Unified Communications Manager Administration GUI

Troubleshooting Other Devices

Use the information in Table 1-7 to troubleshoot problems with Other Devices.

 

Table 1-7 Troubleshooting Other Devices

Problem
Possible Cause
Possible Solution
Presentation Devices
  • Local presentation audio is not playing during a call.

The Secondary Audio Input Source setting may be wrong.

  • Check to see that the Secondary Audio Input Source setting matches the physical cabling.
  • Presentation fails to display in some resume scenarios.

This is expected behavior.

In early CTS software releases, a CTS with its presentation device plugged in would always ask to present when it did a resume.

Presentation device functionality is changed. When a CTS goes on hold, the presentation device takes note whether or not it was the active presenter:

  • If the presentation device was the active presenter when it went on hold, it will ask to present again when taken off hold and the presentation will be shown when the meeting resumes.
  • If it was not the active presenter, it will not ask to present and the presentation will not be shown when the meeting resumes.
  • Administration login can be slow when presenting during point-to-point secure calls.

This is expected behavior.

Administration CLI login can take as much as 60 seconds during point-to-point secure calls when a hold/resume is performed while presenting.


Tip Other devices automatically shut off when there is no longer a video signal to that device. An on-screen timer counts down the remaining time to shut-down. The amount of time that it takes a device to shut down depends on your Unified CM configuration. Most CTS devices that support PiP shut down in 10 to 15 seconds after the video signal is removed. Devices on the CTS 3000 and CTS 3200 series that have black boxes associated with the auxiliary control take 5 minutes to shut down. See the Product Specific Configuration Layout section of the Cisco Unified Communications Manager Configuration Guide for the Cisco TelePresence System for more information about controlling presentation devices and associated displays.
