  • TimePictra can present monitoring results as well as graphs for ePRTC and chains of high performance boundary clocks

Multiple Operation Modes

Mode of Operation is an essential capability focused around which of the multiple inputs can be used as synchronisation reference. The unit can still behave as a fully functional grandmaster from an outputs standpoint and also has the capability to monitor various kinds of inputs, but a key set of specific inputs can be used as reference for a specific Operation Mode. Various Operation Modes will be introduced over time on TimeProvider 4100. TimeProvider 4100 now supports three Operation Modes:

Gateway Clock Mode

  • New class of synchronisation device with multiple inputs and fan out capabilities for distribution of timing flows to multiple end points
  • Translation of PTP timing profiles
  • No license, Gateway Mode is the default of the TimeProvider 4100 device

High Performance Boundary Clock Mode

  • High Performance Boundary clock meets Boundary Clock Class C (10ns cTE) and Class D (5ns Max |TE|)
  • Single Domain (SD) or Multi Domain (MD)
  • MD HP BC is typically used for redundant, resilient and high-accuracy distribution of phase over long distance on optical networks (DWDM)
  • Key element of virtual PRTC (vPRTC) end to end solution
  • Leverages Optical Timing Channel (OTC) : hop-by-hop deployment of TP4100 HP BC at every optical node, with dedicated lambda for time distribution
  • HP BC does not require hardware change, HP BC is enabled by a software option

Enhanced PRTC Mode

  • No hardware needed, ePRTC is enabled via software license
  • TP4100 ePRTC mode meets ITU-T G.8272.1 30ns
  • Flexibility to use a standard Cesium (Time Cesium 4400/4500) or a high performance Cesium (5071A)

  • Holdover Gas Gauge and extended holdover (beyond the 14-day requirement by the standard)
  • Commissioning guidance and recommendations

TimeProvider 4100 Applications

  • Ethernet backhaul-midhaul-fronthaul networks, cable, remote PHY

The Chronos difference

A new generation of communications demands a new generation of timing systems. The TimeProvider 4100 has several “personalities” to suit evolving applications, whether that be a standalone GNSS PRTC clock with support for legacy frequency sync, or as a vPRTC network delivering sub 100ns across your whole network in a scalable, resilient, autonomous, and deterministic way. This one platform performs many timing functions, and Chronos can reuse and redeploy TimeProviders in your network as its demands grow.
