Besides the clock type, each interface can have themaster (M) or slave (S) role. The master sends timing information, and the slave synchronizes itself. Depending on the clock type, an interface can have the master or slave role. It’s also possible that a clock has the master role on...
Clock Types and Operation Modes The types of clocks available are as follows: Grand Master Clock (GMC)—the reference time source derived from an accurate clock such as a GNSS driven clock (i.e. GPS, GLONASS, GALILEO) Boundary Clock (BC)—a network device that acts as slave to its ...
What are the various types of clock entities referred to in PTP? Answer: There are 5 basic clock roles in PTP networks. - PRTC stands for Primary Reference Time Clock. This could be GNSS based or a direct connection to an international time keeping facility. - T-GM stands for Telecom ...
Transparent Clockis the device that has multiple ports connected to boundary clock and ordinary clocks as a bridge between them. It does not behave either clock source or client. Transparent clock updates the correction field within PTP event messages to compensate for the transmit delay. Generally,...

IR8340 supports the following PTP device types: OC-slave , boundary clock, and transparent clock on Default Profile/IEEE 1588. Boundary clock and transparent clock on Power profile. Boundary clock on Dot1as profile. Note Currently all above profiles support two-step mode ...
Clock Type: G.8275.2 profile supports the following clock types: Telecom Grandmaster (T-GM): Provides timing for other network devices and does not synchronize its local clock to other network devices. However, T-GM can be connected to a GPS or GNSS for...
BC(Boundary Clock,边界时钟):有一个以上PTP通信端口的时钟。 TC(Transparentclock,透明时钟):与BC/OC相比,BC/OC需要与其它时钟节点保持时间同步,而TC则不与其它时钟节点保持时间同步。TC有多个PTP端口,但它只在这些端口间转发PTP协议报文并对其进行转发延时校正,而不会通过任何一个端口同步时间。TC包括以下两种类型...
