Clock Admin State The administered clock synchronization state of the
M-SPS module. Possible states are:
• enable - Clock synchronization is enabled on
the device.
• disable, use Internal Clock - Clock
synchronization is disabled on the M-SPS
module. The M-SPS module uses its internal
low accuracy (
± 20 ppm) oscillator.
Clock Status The status of clock synchronization on the device.
Possible statuses are:
• locked - The M-SPS module is using a clock
which is locked to the input timing source.
• holdover - The M-SPS module is simulating a
clock to which it was previously locked. This
state will last until the clock source is fixed.
• free_running - The M-SPS module is using its
±4.6 ppm oscillator to generate timing. This only
occurs after a reset when there are no healthy
timing sources available or when all four
sources are configured with a priority of 0.
• internal - Clock synchronization is disabled and
the M-SPS module is using its low accuracy
(±20 ppm) internal oscillator to generate timing.
Configuration Symbol For Module Configuration: The version of the
module. The version is updated whenever there is a
functional modification to the module.
For Agent Configuration: The version of the
hardware and firmware of the agent.
Connected To The DomainX to which the selected module is
connected - DomainXL for the left DomainX and
DomainXR for the right DomainX.
Current Source The current source clock used for clock
synchronization. Possible sources are:
• ATM A/B - An ATM port on the device.
• SYNC A/B - An external source connected to the
front panel of the M-SPS.
• none - No recognizable clock source.
