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.
