ITU-T O.172-2005 发布历史
This Recommendation specifies test instrumentation that is used to generate and measure timing jitter and synchronization wander in digital systems based on the Synchronous Digital Hierarchy (SDH). This Recommendation also specifies requirements for the measurement of SDH tributaries operating at PDH bit rates. The test instrumentation consists principally of a jitter/wander measurement function and a jitter/wander generation function. Measurements can be performed at the physical layer of SDH systems. A bit-error rate test set may also be required for certain types of measurements; this may be part of the same instrumentation or it may be physically separate. Test instrumentation for the generation and measurement of jitter and wander in digital systems based on the Plesiochronous Digital Hierarchy (PDH) is specified in ITU-T Rec. O.171 [18]. It is recommended that ITU-T Recs G.783 [6], G.812 [9], G.813 [10], G.825 [13] and G.798 [15] be read in conjunction with this Recommendation.
