Automatic Identification Of The Cascading Link; Basic Cascading Using Isdn-Video Cascaded Link; Network Topologies Enabling Content Sharing Over Isdn-Video Cascaded Links - Polycom RealPresence 1800 Administration Manual

Once the DTMF codes are entered and forwarded to the Entry Queue on MCU B, the IVR session is
completed, the participant moved to the destination conference and the connection between the two
conferences is established.

Automatic Identification of the Cascading Link

In both dialing methods, the system automatically identifies that the dial in participant is an MCU, 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.

Basic Cascading Using ISDN-video Cascaded Link

ISDN-video 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-video Cascading Link.
Network Topologies Enabling Content Sharing Over
ISDN-video Cascaded Links
ISDN-video Cascaded links that support content sharing can be created between two gateways,
gateway-to-MCU or between two MCUs in the following network topologies:
● Gateway to Gateway
Gateway to Gateway Topology
In this topology, an IP participant calls another IP participant over an ISDN-video link between two
gateways.
● Gateway to MCU
Gateway to MCU/ MCU to Gateway Topology
In this topology, an IP participant calls a conference running on an MCU via a gateway and over an
ISDN-video link.
