RealPresence Collaboration Server (RMX) 1500/1800/2000/4000 Getting Started Guide
● Although PCM is successfully initiated on Microsoft Office Communications client or Lync client, since
FECC feature is not available on these clients none of the PCM options are accessible as the only
available keys are #,*,1..9 and not the navigation keys ("LEFT", "RIGHT", etc.).

System Flags

Two system flags can be used to affect PCM behavior: PCM_FECC and NUM_OF_PCM_IN_MPMX.
These System Flag must be added to the System Configuration file before it can be modified. For more
information see the Polycom® RealPresence Collaboration Server (RMX) 1500/1800/2000/4000
Administrator's Guide, Modifying System

Modifying the PCM_FECC System Flag

The PCM_FECC System Flag determines whether the DTMF Code, ##, the Arrow Keys (FECC) or both will
activate the PCM interface. In addition, this flag can be used to disable the PCM.
Possible Values: YES / NO
Default: YES.
The table below summarizes the combined effect of the DTMF Code and PCM_FECC System Flag settings
on the system.
PCM_FECC / DTMF Code
PCM_FECC= DTMF Code
YES
NO

Modifying the NUM_OF_PCM_IN_MPMX System Flag

The NUM_OF_PCM_IN_MPMX system flag determines the maximum number of PCM sessions that can
be activated from conferences per MPMx card installed in Collaboration Server (RMX) 1500/2000/4000,
depending on the system's SVC license.
● In systems with SVC-enabled license, the only possible (and default) flag value is 1.
● In systems with SVC-disabled license, possible flag values are 1 to 4. Default value is 4.
