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-A 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 9
.
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-A. 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.
