is connected, this terminal is called as the secondary terminal.
When the secondary terminal is connected, some of the
function is limited as follows:
When a normal phone is connected
You can connect only one normal audio phone in the network.
If two phones try to connect, the system will disconnect its line
or reject the call.
The audio mode of the other terminals is not influenced:
• Once a phone is connected.
• After the normal phone ends a meeting.

and via 1B-channel with the 1B-channel terminals. The
meeting with the 1B-channel terminals is as follows:
• Send/receive the audio.
• Receive the video.
If 2B-channel terminals end a meeting, and only 1B-channel
terminals are in the network, the meeting holds via 1B-channel.

When holding a meeting in the 64 K network, the 56 K
terminal is connected
