Product Description
The T600-BDOCB NTP Time Server supports the NTP and SNTP network synchronization protocols and is a high-precision, high-capacity, and highly secure clock product. The device hardware features a redundant architecture design, with high-precision clocks directly sourced from the B3P code signals of the BeiDou-2 B3 satellite. It tames the local clock source through signal analysis to achieve precise clock maintenance even after satellite signal loss. The device software incorporates various interference detection and identification algorithms developed by Beidou Bantai to detect signal anomalies caused by interference and malicious attacks on satellite signals.
With its unique embedded hardware design and efficient Linux operating system, it allows for flexible expansion of multiple clock signal outputs. It fully supports the latest NTP time synchronization protocols, MD5 secure encryption protocol, and certificate encryption protocol, with network time accuracy reaching the microsecond level. It also supports TOD, 10MHz, 1PPS, log recording, USB port for upgrade downloads, and dry contact alarm functions. When combined with the proprietary network-wide time monitoring software developed by Beidou Bantai, it enables easy network time synchronization and effective monitoring.
The T600-BDOCB Standard Time Synchronization Clock supports the reception of BD2 B3 frequency signals, with each frequency supporting up to 16 channels simultaneously. After the welding of the RPM chip, it can support the reception of B3P code on all 16 channels simultaneously.
