Product overview
SYN2138 The CDMA time server obtains the standard time signal information from the CDMA network, that is, getting the Beijing time from the CDMA base station. It can be conveniently deployed in any place with CDMA signals, especially suitable for deploying occasions where it is not convenient to install the GPS/ Beidou antenna. It is equipped with the output of 1 NTP network timing ports, which can be extended to 4 roads at most, and each path is independent and backup each other.
The clock synchronization server has the functions of password authentication, firewall protection, SYN-flood defense, encrypted communication, heartbeat detection, redundant backup, remote maintenance and real-time monitoring. Many time servers or multiple network ports can be set up as the same IP, which is redundant backup each other.After many iterations, the time synchronization server integrates WiFi wireless management function on the basis of wired management, so that users can directly manage the time synchronization server with mobile phones.
Key word : clock synchronization server, PC time synchronization server, time synchronization server.
