+Service include 12 monthly certificates of calibration, automated data transfer (in and out), data processing, technical support on a 8x5 basis, maintainance and data monitoring. This service is intended to provide the user's local frequency standard with a frequency traceability to UTC via the french national reference UTC(OP) at 1x10<sup>-13</sup> level (after 30 days). This service can be found in our [[http://www.cofrac.fr/annexes/sect2/2-06.pdf|2-06 accredited scope]] (internal procedure PT-54).
