Structuring and controlling the conference system
Large conference system with redundant ring topology
The redundant ring topology ensures that, shou
ld one conference unit or system
cable fail or be manipulated, all other conference units of the cable ring will con-
tinue to function reliably.
For setting up a large conference system with redundant ring topology, you require
one ADN CU1 central unit for controlling the conference and additional ADN PS
power supplies for powering the conference units. The conference units are inter-
connected in rings and two rings can be connected to each ADN PS power supply
(see page 60).
When connecting the conference units to an ADN PS power supply, you can
mix different cable topologies (simple cabling with cable strings or redun-
dant ring topology) as long as you ensure correct cabling and comply with
the specifications (see page 58 and page 60).
