The following diagram shows an example of a digital conference.

Figure 2.24: Digital conference

Configuring a digital conference

See Figure 4-26.

The DTE of sub-station 1 in node 2 must be connected to interface 5 of the

DSK module.

Using the "STANDARD" function, converter 5 of this interface must be

connected to another converter (converter 6 n the above example) of the

module.

In the central card slot data of the module, this converter 6 must be defined

as "Digital conference converter 6". Converter 6 then sends its data via the

AND link to converter 1 of the module and thus to the main station.

Converter 1 of the module receives the main station signals and passes

them on to the other sub-stations. In the transmit direction, this converter 1

is used to send the signals from the sub-stations to the main station.

There is a channel link between converter 1 and channel 6 of port 1. The 2

Mbit/s connection is used to transmit channel 6 to node 1.

In node 1, there is a channel link between channel 6/port2 and converter 4

of the DSK module. The main station is connected to interface 4 of the DSK

module.

Channels from another node, e.g. channel 9 / port 2, are applied to a

converter available on the module by means of the "STANDARD" operating

mode. In the example described, channel 9 is applied to converter 4.

Converter 4 must be defined as "Digital conference converter 4" in the

central card slot data.
