Notes On Secondary Terminals - Sony PCS-1500 Operating Instructions Manual

Notes on Secondary Terminals

If the terminal that is not adequate for
the setting on this system 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.
When the slave terminals via 1B-
channel and 2B-channel are
mixed when NUMBER OF LINES
is set to 2B
Holds a meeting via 2B-channel with
the 2B-channel terminals 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. This
1B-channel meeting can send/receive
the audio and video.
When holding a meeting in the
64 K network, the 56 K terminal
is connected
The system automatically changes the
transfer rate to 56 Kbps. The slave
terminal that cannot change the rate
becomes the secondary terminal.
The meeting with the secondary
terminal is as follows:
• Send/receive the audio.
• Receive the video.
When the different audio mode
terminal is connected, and the
video mode is different
The system automatically changes the
video rate to the lowest one. The slave
terminal that cannot change the video
rate becomes the secondary terminal.
The meeting with the secondary
terminal is as follows:
• Send/receive the audio.
• Receive the video.
When the terminal whose video
rate is lower is connected
Broadcasts the picture to all the
terminals with the lowest frame rate in
the network.
When the terminal whose video
mode is only QCIF is connected
Does not broadcast the picture to the
QCIF terminal.
When VIDEO MODE is set to
H.263
The H.263 mode is only available
when all the terminals are in H.263
mode. If there is a terminal in H.261
mode, the meeting will be held in
H.261 mode.
