L7000-PTP Master ClockPTP master clock

Product Overview

The L7000-PTP master clock is a cost-effective PTP master clock product that supports IEEE1588-2008, IEEE802.1AS-2011, GPS/BeiDou satellite timing, PPS/TOD output, NTP, and can be flexibly configured through WebUI. Its main features include providing accurate, reliable, and secure high-precision satellite time reference for network devices, terminals, and servers within firewalls, and supporting time synchronization for tens of thousands of clients that support standard Network Time Protocol (NTP, including V1/2/3/4) and Simple Network Time Protocol (SNTP). The PTP master clock has been widely used in various fields such as finance, transportation, securities, electricity, mobile communications, petroleum, industry, e-commerce, industrial automation, cloud computing, security, smart cities, IoT, energy, and national defense.

Suitable for systems with strict requirements for time synchronization accuracy and requiring high-precision timing, it can continuously provide timing services after GPS/BeiDou system failure or antenna failure, with 24-hour timing accuracy better than 300 nanoseconds and 1-year deviation better than 3 milliseconds. It provides a refund guarantee, three-year warranty, and free technical support for life.

port configuration

Packet configuration description:

• Port: Displays the port name and is non-editable.

• Protocol: Select the transmission protocol, which can be UDP/IPv4, UDP/IPv6, or L2.

• Delay Mechanism: Selection of delay mechanism, with options including End to End or Peer to Peer.

• Announce Interval: The interval for Announce messages, which is a power of 2 of the configured value, measured in seconds.

• Announce Receipt Timeout: The number of Announce message reception timeouts. Since the last received Announce message, if the number of unreceived Announce messages exceeds this value, it is considered a timeout.

• Sync Interval: Sync message interval, with the interval time being a power of 2 of the configured value, in seconds.

• Min Delay Interval: The minimum allowable interval for Delay_Req messages, where the interval time is a power of 2 of the configured value, with the unit being seconds.
