DMA OperationsGuide MCUs
124 Polycom, Inc.
Busy Out Stops the Polycom DMA system from creating new
conferences on the selected MCUs, but allows existing
conferences to continue and accepts new calls to those
conferences. A dialog box asks you to confirm.
If any of the MCUs are ISDN gateways, the system stops
using them for simplified gateway dialing.
This gracefully winds down the system’s use of the MCU as
a conferencing resource. It has no effect on the MCUs
themselves, which continue to accept any calls from other
sources.
Quarantine Allows the selected MCUs to register (or remain registered),
but not to make or receive calls.
If the selected MCUs are quarantined, this becomes
Unquarantine.
Block Prevents the selected MCUs from registering.
If he selected MCUs are blocked, this becomes Unblock.
Note In the recommended high security mode, the Polycom DMA system uses only
HTTPS for the conference control connection to MCUs, and you must configure
your MCUs to accept encrypted connections. We recommend doing so. When
unencrypted connections are used, the MCU login name and password are sent
unencrypted over the network.
The Polycom DMA system knows only what resources an MCU has currently
available. It can’t know what’s been scheduled for future use.
If you have a Polycom CMA system and want to use the same RMX MCU (v6.0 and
above) for both reservationless and scheduled conferences, determine how many
ports you want to set aside for scheduled conferences and designate those as ports
reserved for the CMA system. This feature is not available for Cisco Codian MCUs
or for use with a Polycom RealPresence Resource Manager system. The
RealPresence Resource Manager system must have exclusive use of any MCUs
on which it directly schedules conferences. Those MCUs should not be added to
the DMA system’s conferencing resources.
The Automatic Password Generation feature, introduced in RMX version 7.0.2, is
not compatible with the Polycom DMA system. On Polycom RMX MCUs to be used
with the Polycom DMA system, disable this feature by setting the system flags
NUMERIC_CONF_PASS_DEFAULT_LEN and
NUMERIC_CHAIR_PASS_DEFAULT_LEN both to 0 (zero).
