Notes
for clocking
MPI The network clock is enabled
only when the span coming from
the DCE to the MCU is active
(i.e. handles a call). Therefore,
the spans defined as primary
and backup clock must be
connected first when starting a
conference, and disconnected
last when terminating the
conference.
MPI The network clock is enabled
only when the span coming from
the DCE to the MCU is active
(i.e. handles a call). Therefore,
the spans defined as primary
and backup clocks must be
active at all times (i.e. leased
mode).
