DMA Operations Guide MCUs
122 Polycom, Inc.
Signaling Type The type of signaling for which the MCU is configured:
H.323, SIP, or both.
Ports Reserved The number of video and voice ports on the MCU that are
reserved for the Polycom CMA system and therefore
off-limits to the Polycom DMA system. Applies only to MCUs
that are enabled for conference rooms (available as a
conferencing resource for the Polycom DMA system’s
Conference Manager).
Reserving a portion of an MCU’s capacity for the Polycom
CMA system enables that portion to be used for scheduled
conferences (where MCU resources are reserved in
advance).
This feature is available only on RMX v. 6.0 or later MCUs
and with a Polycom CMA system. It’s not available for use
with a Polycom RealPresence Resource Manager system,
which can’t share MCUs with the DMA system.
Prefix The dialing prefix assigned to the MCU, if any. MCUs without
a prefix are unavailable for direct prefix-based dialing.
MCUs don’t need a prefix to be used as conferencing
resources by the Conference Manager.
Registration Status The registration status of the device:
• Active — The device is registered and can make and
receive calls.
• Inactive — The device’s registration has expired.
Whether it can make and receive calls depends on the
system’s rogue call policy (see “Call Server Settings” on
page 221). It can register again.
• Permanent — The device’s registration never expires.
• Quarantined — The device is registered, but it can’t
make or receive calls. It remains in Quarantined or
Quarantined (Inactive) status until you remove it from
quarantine.
• Quarantined (Inactive) — The device was quarantined,
and its registration has expired. It can register again,
returning to Quarantined status.
• Blocked — The device is not permitted to register.
Whether it can make and receive calls depends on the
system’s rogue call policy. It remains blocked from
registering until you unblock it.
A device’s status can be determined by:
• An action by the device.
• An action applied to it manually on this page.
• The expiration of a timer.
• The application of a registration policy and admission
policy (see “Registration Policy” on page 248).
