Setting Description
Near End Loop Available only out of a call. Tests the internal audio
encoders and decoders, external microphones and
speakers, internal video encoders and decoders, audio
hardware, external microphones, speakers, cameras,
and monitors. Monitor 1 displays the video and plays
the audio sent to the far site in a call.
Ping Tests whether the system can connect with a far-site IP
address that you specify. Ping returns abbreviated
Internet Control Message Protocol results. If you’ve
configured the far site for H.323, it returns H.323
information. It returns SIP information only if you’ve
configured the far site for SIP. If the test is successful,
the system displays a message.
Trace Route Tests the routing path between the local system and
the IP address you enter. If the test is successful, the
system lists the hops between the system and the IP
address.
Color Bars Tests the color settings of your monitor for optimum
picture quality. If the color bars generated during the
test aren’t clear, or the colors don’t look correct, adjust
the monitor settings.
Speaker Test A 473 Hz audio tone indicates whether the local audio
connections are correct. If you run this test during a
call, the far site hears the tone. You can test the left or
right speaker. If Start Both is displayed, you can also
test both speakers at the same time.
