Field Name	Description


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.
