Cascading Via Entry Queue - Polycom RMX 1500 Administrator's Manual

Cascading via Entry Queue

The link between the two conferences is created when a participant that is
defined as a dial-out cascaded link in one conference (Conference A)
connects to the second conference (Conference B) via a special cascaded
Entry Queue (EQ). When MCU A dials out to the cascaded link to connect
it to conference A, it actually dials out to the cascaded Entry Queue
defined on MCU B.

Though the process of cascading conferences mentioned in this section
refers to conferences running on two different RMX units, it is possible to
cascade conferences running between RMX units and other MCUs.
The following features are not supported by the cascaded link and
therefore are not supported in the combined conference:
• DTMF codes are enabled in cascaded conference, but only in their
local conference. The operations executed via DTMF codes are not
forwarded between linked conferences.
• FECC (Far End Camera Control will only apply to conferences
running in their local MCU).
