TimeProvider® 4100 Version 2.2

TimeProvider 4100 is a best-in-class IEEE 1588 grandmaster with extensive port fanout for PTP, NTP, SyncE and legacy ports such as E1/T1, 10 MHz, ToD and 1 pps. TimeProvider 4100 is a family of devices that offers a choice of oscillators, expansion modules (E1/T1 or 10GE/1GE) and operation modes. Operation Modes are configurations with specific capabilities, all based on the same device, which can act as a:

  • Gateway Clock
  • High-Performance Boundary Clock
  • Enhanced Primary Reference Time Clock (ePRTC)

TimeProvider 4100 v2.2 expands on three key core capabilities that are necessary for operators of critical infrastructure:

  • Redundancy via a software schema and direct Ethernet connections between two units
  • Resiliency with new GNSS multiband support as well as a new super OCXO oscillator option for enhanced holdover and timekeeping
  • Security via new TACACS+ and RADIUS authentication mechanisms as well as additional anti-jamming and anti-spoofing measures

TimeProvider 4100 is a key element of the virtual PRTC (vPRTC) end-to-end solution composed of Cesium atomic clocks, BlueSky™ GNSS Firewall, TimeProvider 4100 ePRTC, TimeProvider 4100 chain of high-performance boundary clocks, TimeProvider 4100 gateway clocks and TimePictra® Synchronization and Management System.

BlueSky™ Technology Now Inside the SyncServer S600/S650 Time Server

The new SyncServer with BlueSky technology detects GPS jamming and spoofing re­lated anomalies in real-time to protect essential time and frequency outputs. When unexpected changes are detect­ed and trust is compromised, alarms are sent and the BlueSky detectors respond to protect the ongoing integrity of the SyncServer’s timing operations.

  • Protection from localized GPS jamming and spoofing
  • Automatic failover to alternative time sources or holdover on alarm
  • Graphical tools for site survey, historical performance and event analysis 

BlueSky™ GNSS Firewall – Software Release 2.0

The BlueSky GNSS Firewall is a cost-effective overlay solution that is installed between existing Global Navigation Satellite System (GNSS) antennas and GPS systems. Similar to a network firewall, the BlueSky GNSS Firewall protects already-deployed GPS systems inside the firewall from untrusted, sky-based signals outside the firewall. Software Release 2.0 includes charting and advanced threshold settings of GNSS observables such as satellites-in-view, carrier-to-noise, position dispersion, phase time deviation and Radio Frequency (RF) power level to simplify system turn-up and deployment.

  • Protects GPS systems from spoofing and jamming
  • Hardened GPS output provides secure signal that is isolated from live-sky interference
  • Optional internal Miniature Atomic Clock (MAC) for extended holdover and enhanced detection
  • Seamless integration of BlueSky performance monitoring within TimePictra® software suite

TimePictra® Synchronization Monitoring and Management System

Reliable packet-based networks require powerful, dependable and intelligent management tools. The TimePictra software suite provides control and visibility of the entire end-to-end synchronization network including the virtual Primary Reference Time Clock (vPRTC).

  • Web-based multi-tier software architecture
  • Intuitive web Graphical User Interface (GUI) for easy management
  • Scalable architecture for future expansion
  • Northbound Operations Support System (OSS) integration
  • End-to-end Precision Time Protocol (PTP) management

Featured Applications


 Virtual Primary Reference Time Clock


The virtual Primary Reference Time Clock (vPRTC) is a highly secure and resilient network-based timing architecture that has been developed to meet the expanding needs of modern critical infrastructures. It blends proven timing technologies into a centralized and protected source location and then uses commercial fiber optic network links and advanced IEEE® 1588 Precision Time Protocol (PTP) boundary clocks to distribute 100 ns PRTC timing where it is needed in end points that might be hundreds of kilometers away.
