Stratum3 and 3E Oscillator Requirements

Stratum 3 and Stratum 3E oscillators have two frequency stability specifications (Free Run and Holdover). Bellcore has somewhat defined a third requirement, Drift. The Drift requirement is not per say a Bellcore specification. However Bellcore suggests that the Drift be used for calculating the Holdover specification and suggests Drift values.
