When one MCU is down (for example, power shortage), the gatekeeper will 
identify that one MCU (A) is unavailable and will automatically forward the 
calls to the second MCU (B). The participants are connected to the 
conference that was copied from MCU A with the same name.
When the first MCU (A) is up and running again, the gatekeeper will connect 
the participants to conferences running on MCU A. If a conference with the 
same ID is now running on both MCUs (for example, if MCU A recovered 
quickly, participants that connected later were connected to MCU A), the 
system will automatically cascade both conferences (using the Auto Cascade 
feature) to create one conference. This will eliminate the need to disconnect 
and reconnect participants to a single conference.
If the origin conference is terminated on one MCU its backup conference will 
be automatically terminated on the second MCU.
In the same way, if ISDN PBX is configured to route calls from one MCU to 
another according to MCU availability, the same behavior will occur.
Redundancy Guidelines
ISDN and IP Network Services must have the same configuration (for 
example, MCU Prefix in gatekeeper, dial-in numbers range, etc.) on both 
MCUs.
Conference Profiles, Entry Queue and IVR Services must be identical on 
both MCUs.
Entry Queues must be identical on both MCUs.
The following conference parameters are copied from the source MCU 
to the target MCU (backup):
Conference duration
Passwords (chairperson and conference entry)
User Defined fields 
Billing Code
Lecture Mode parameters
Layout and Auto Layout
The Central Server Service is disabled in Secure Mode.
