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.
