tSyncIfTimingAdmRefOrder1
1.3.6.1.4.1.6527.3.1.2.2.8.2.1.1.2
The value of tSyncIfTimingAdmRefOrder1 specifies the most preferred
timing reference source.
The synchronous equipment timing subsystem chooses a timing reference
based on priority.
The user can configure the priority order of the following timing
reference inputs ('bits', 'reference1', 'reference2', and 'ptp').
If the platform does not support that timing reference input, it
cannot be configured in the reference priority order. For example,
the 'bits' timing reference cannot be configured on a 7750 SR-c12
system.
Other values of TmnxSETSRefSource (e.g. 'bits2') cannot be configured
in the reference order.
