Notes on Secondary Terminals
If there is a terminal that is not adequate for the settings set by this system, that terminal is called the secondary terminal.
Communication capabilities between the secondary terminal and this system are shown below.
•Sending/receiving audio
•Receiving video from the secondary terminal
•Disables transmission of video to the secondary terminal
For details on the secondary terminal, see the glossary on page 224.
When a normal phone is connected
The audio mode of the other terminals is not affected if a normal phone is connected or disconnected any time.
When terminals with “Far End Camera Control” set to “On” and “Off” are mixed
As the bit rate of video signals differs depending on the setting of “Far End Camera Control”, the picture is not displayed on some terminals.
When a 56K network is mixed among the terminals if the conference is held via 64K network
The conference automatically changes to that via 56 K network. Terminals that cannot change to that network are regarded as secondary terminals, and the transmission of video is not available.
When a terminal with different audio mode is connected and its video bit rate is different
The conference is conducted in the video mode according to the terminal with the lowest video bit rate. A terminal that cannot fit this rate is regarded as a secondary terminal, and the transmission of video is not available.
When a terminal whose video mode is QCIF standard only
The system does not send video to the QCIF terminal.
