Clock Quality:
Clock Accuracy: A number describing the accuracy of the oscillator in the Master
relative to its UTC reference (see IEEE Standard 1588-2008, Section 7.6.2.5).
Offset Scaled Variance: A constant value based on the variance of the oscillator
installed in the SecureSync unit.
Clock Class: A number describing the state of the time and 1pps references of the
PTP Clock.
See table below for Clock Class definitions (see also: IEEE Standard 1588-2008,
Section 7.6.2.4, Table 5).

Clock Class Definition
6 13 Time and 1pps references are synchronized with the host references and PTP
clock shall not be a slave to another clock in the domain.
7 14 Time and 1pps references are in holdover state, within specifications and PTP
clock shall not be a slave to another clock in the domain.
52 58 Time and 1pps references are in holdover state, not within specifications, and PTP
clock shall not be a slave to another clock in the domain. Then, applied to Master
Clocks who have just powered on and have not yet achieved a suitable TFOM
value.
187 193 Time and 1pps references are in holdover state, not within specifications, and PTP
clock may be a slave to another clock in the domain.
255 255 Class assigned to “Slave-Only” clocks.
248 248 “Unknown” class.
Ethernet Status
Current IP Address: The IP address currently being used by the PTP interface.
Note: If the PTP Module is set up for DHCP but fails to obtain an IP address,
it will use the Static IP instead. To reacquire a DHCP address, reset the
module via the Main tab in the PTP settings window.
