2.6.2.4 Examples
The following EDC examples show a pure 8-subscriber conference and a
mixed 8-subscriber and 2 x 4-subscriber conference.
Example of an 8-subscriber conference
All subscribers in this example participate in conference A. The subscribers
of conference A are connected via a module configured for an 8-subscriber
conference by means of the central card slot data.

Main line
The main line of the conference is routed from node 1 (Central Station) via
nodes 2, 3, 5 and 6 in channel 10. For main line routing, converters 1 and 2
of the modules are connected to the corresponding ports (64 kbit/s
channel). Along this main line, subscribers A-1 to A-3 as well as A-4 to A-7
are involved in the conference.
Sub-line
Subscriber A-4 is connected to the conference in node 3 via a sub-line. For
this purpose, channel 14 (subscr. A-4) is switched through transparently in
node 2 to node 3. In node 3, this channel 14 is then applied to a free
converter.
