normal phone is connected or disconnected
at any time.
When a 56K network is mixed among
the terminals if the connection is
made via a 64K network

cannot change to that network are regarded
as secondary terminals, and the transmission
of video is not available, although
transmission/reception of audio and
reception of video are available.
When a terminal with different audio
mode is connected and its video bit

available, although transmission/reception
of audio and reception of video are
