11.9.4 SSU Types V & VI
11.9.4.1
At Constant Temperature Expressed as MTIE
Standard: Draft ITU-T Recommendation G.812 (09/97)
File name: WANDER GENERATION SSU V&VI G812.mti
Object to which the specification applies: Synchronisation Supply Unit (SSU) Types
V & VI
Specified quantity and measurement conditions: The wander at the output of a
Synchronisation Supply Unit of Type V or VI must meet this mask when the input is
connected to an ideal reference signal and when the ambient temperature is
constant (+ 1 K).
Mathematical description (as specified in the standard):
MTIE [ns]
1000
Observation Interval [s]
τ > 100
Template (circles = points stored in the WinSTS template file):
MTIE [s]
1.00E-05
1.00E-06
1.00E-07
1.00E-08
1.0E-01
1.0E+01
1.0E+03
Observation Interval [s]
Comments: For testing, the reference signal applied to the input of the clock must
have a stability level that is at least 10 times better than the above output
requirement.
