This document describes a recommended methodology for modeling and measuring the performance of slave stratum clock equipment in telecommunication networks. This methodology has been developed by the T1X1.3 Synchronization Working Group of ANSI accredited committee T1 Telecommunications based on an ongoing study of the performance of slave clocks in actual network environments. It is recognized that current slave clock standards are not adequate to ensure acceptable timing performance in future networks. The methodology presented here may be the basis of enhancing the current stratum clock specifications in ANSI T1.101-1987
