Connection Examples of a Multipoint Connection
Multipoint connection for up to 3 points is available by using the optional
PCSA-B384S or PCSA-B768S ISDN Unit.
Notes on the number of ISDN lines used and number of remote
parties for a multipoint connection
You can select the number of ISDN channels to be used for the remote point
connected first using “ISDN Bandwidth” on the ISDN: Mode page of the
Communication setup menu (page 61).
However, if the number of remote points connected increases as a result of
dialing from the main terminal, some of the channels used for the first point
will be cut off and used for newly connected points instead. For example,
if you use six ISDN lines (up to 12B channels available), 12B channels will be
used for the first remote point only when no other points are connected. When
the system connects to a second point, the number of channels for the first
point decreases, and 6B channels will be used for both the first and second
points.
Even if one of the remote points in a multipoint connection is disconnected, the
number of channels used for the remaining points will not increase.
When you are called from a remote party and the remote party has set up a lower number
of ISDN channels than that in your terminal, the setting on the remote party’s terminal
has priority.
