Multipoint Switching
In a multipoint configuration the communication between different stations is done by using a
common media. In a PBX system this can be achieved by connecting all stations to one (or more)
time-slots and transmitting the information back. Multipoint switching is a special form of
conferencing for data communication. In contrast to audio conferences terminals broadcast data to
the MUSAC which are only “or-connected”. That is, at each bit time, the “conference sum” is “1” if
the input of one or more terminals is “1”; otherwise, the result is “0”. A simple example of such a
system using Siemens VLSI switching devices is shown in
figure 8
.
ISDN subscribers are connected via line cards and PCM highways to a multipoint switching matrix.
The data from different terminals are summed up in the multipoint switching matrix and transmitted
back to all stations. The switching matrix is build by using just one MUSAC. Every combination of
subscribers may be switched to the same transport media (time-slot), in this way enabling a number
of powerful multipoint communication systems.
