external microphones and speakers, the internal video
encoders and decoders, audio hardware, and the
external microphones, speakers, cameras, and
monitors.
Monitor 1 displays the video and plays the audio that is
sent to the far site in a call.
This test is not available when you are in a call.
Tests whether the system can connect with a far-site IP
address that you specify.
PING returns abbreviated Internet Control Message
Protocol results. It returns H.323 information only if the
far site is configured for H.323. It returns SIP
information only if the far site is configured for SIP.
If the test is successful, the system displays a
message.
Tests the routing path between the local system and
the IP address entered.
If the test is successful, the system lists the hops
between the system and the IP address you entered.
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.
Tests the audio cable connections. A 473 Hz tone
indicates that the local audio connections are correct.
If you run a test during a call, people on the far site also
hear the test tone.

microphones, far-site audio, and any device connected
to the audio line in.

the room system.
