Product Overview

KMTS receives synchronization signals from GNSS or higher-level offices, including 2.048 MHz synchronization, E1/T1, PTP, ToD, and external clock inputs.

Based on these reference signals, it generates frequency synchronization outputs such as E1, T1 and distributes them to various digital communication equipment and lower-level offices.

In addition, KMTS provides PTP Grandmaster and Stratum-1 NTP Server functions for packet network synchronization, delivering highly accurate timing information to PTP Slaves and NTP Clients.
