New troubleshooting features in TC6

A Diagnostics section on the web interface was introduced in the software version TC6.0. if there is

a problem with your system you will see a notification in the Home screen when you first login to the

web interface. From here you can click on

problem (Figure 6).

Figure 6 - Potential Problem with Your System

Once you have clicked this link or clicked

Diagnostics -> Troubleshooting

tics run on the system with any error messages highlighted in red with Error. in the example below you

can see that the system is set to use H.323 as the default call protocol, but H.323 has been disabled

meaning all calls will fail by default.

For descriptions about warning and error messages displayed on this screen in the web interface and

possible methods to resolve these see "Appendix E – Web diagnostics and on screen error messages

Video problems

if you are having problems with the video quality there can be several reasons for this. The problem

may be your equipment, but it can also be a fault from the far-end that you are seeing and issues can

be related to multiple factors. it is important to identify the source of the problem and then troubleshoot

from there.

One of the first questions to ask is are these problems only seen in a call. if you turn on self–view outside

of a call, is the image quality stable and of good quality on your local system?

Figure 8 - Location of self-view button on Touch and remote control

if your self-view looks good, you can probably rule out hardware issues with your equipment and

should investigate:

•

"Settings effecting video quality" on page 7

•

"Network related issues" on page 8

•

"interoperability issues" on page 9

•

"Far-end problem" on page 10

if your self-view image has issues the problem is most likely with your system. Some possibilities are:

•

"Camera" on page 16

•

"Monitor" on page 11

•

"Codec – no self-view" on page 10

•

"Cabling" on page 11
