Data Flow

3-114
In a dial-out conference (Figure 3-1), the MCU dials the number of the
endpoint. This number is transferred via the switch (which is connected to the
ATM network) to the V-Gate. The V-Gate translates the dialed number to the
appropriate UNI address and sends it back to the MCU. The MCU now
connects to the endpoint.

In a dial-in conference (Figure 3-2), the endpoint dials the MCU number. This
number is transferred via the switch (which is connected to the ATM network)
to the V-Gate. The V-Gate translates the dialed number of the MCU to the
appropriate UNI address and sends it back to the endpoint. The endpoint now
connects to the MCU.
