¿µ¹®³»¿ë¿ä¾à This standard allows for proper network operation for phase/time synchronization distribution when a network equipment embedding an APTS or a PTS clock is timed from another telecom boundary clock (T-BC) or a telecom grandmaster (T-GM). This standard specifies the minimum requirements for APTS and PTS clocks in network elements (NEs). This standard includes noise generation, noise tolerance, noise transfer, and transient response for APTS and PTS clocks.
