- Stratum (disambiguation)
* A
stratum (plural: "strata") is the basic unit of lithologicstratigraphy .* In
telecommunications , the term "stratum" is used to describe the quality of a clock used for synchronization. The ANSI Synchronization Interface Standard T1.101 defines profiles for clock accuracy at each stratum level, as does ITU standard G.810, and Telecordia/Bellcore standards GR-253 and GR-1244.* The term "stratum" is also used to define the levels in the hierarchy of clocks defined by the
Network Time Protocol . There is no direct relationship between the NTP synchronization stratum levels and those of the ITU or ANSI-defined synchronization hierarchy: in NTP, stratum numbers are incremented each time a clock is passed from one device to another, while in telecommunications, the same stratum level can be passed from device to device.*
