Basic Cascading using ISDN Cascaded Link

Automatic Identification of the Cascading Link

In both dialing methods, the system automatically identifies that the dial
in participant is an MCU and creates a Cascading Link and displays the
link icon for the participant (
randomly defined by the MCUs during the negotiation process of the
connection phase.
ISDN connection can be used to link between two MCUs or MCU and
gateway and create a cascading conference. Content can be sent across the
ISDN Cascading Link.

Network Topologies Enabling H.239 Content Over ISDN

Cascaded Links

ISDN Cascaded links that support H.239 Content can be created between
two gateways, gateway-to-MCU or between two MCUs in the following
network topologies:
• Gateway to Gateway
RMX Gateway A
Figure 4 Gateway to Gateway Topology
In this topology, an IP participant calls another IP participant over an
ISDN link between two gateways.
