Product Overview

STS-96 receives synchronized signal of 1 level from GNSS or higher rank office and generates frequency synchronized signals, such as E1, T1, 2M, CC, RS-422 etc., to all kinds of digital communication equipment and lower rank office. In Addition, PTP GrandMaster and Stratum1 NTP Server function for time synchronization in the Packet network, supplying precise time information to PTP Slave and NTP Client. Also, it is capable of generating various time synchronization signals such as IRIG-B (000.120), ToD (Time of Day), and 1PPS (Pulse Per Sec.) for time synchronization of power systems and other systems.
