Telecom Primary Reference Sources

 In the operation of Carrier-Class communication networks, secure and accurate timing is absolutely vital. When something means this much to your business and meeting the needs of your customers, compromise is simply not an option.

TimeSource Enhanced PRTC (ePRTC)

TimeSource Enhanced PRTC (ePRTC) (Datasheet)

The TimeSource Enhanced PRTC (ePRTC) is designed to meet the newly consented ITU-T Recommendation G.8272.1 for enhanced Primary Reference Time Clocks and provides a unique solution to help protect telecom and mobile networks against GNSS vulnerabilities. Using an innovative approach to "generate time" by producing its own timescale which is driven by high performance Cesium frequency standards and aligned with GNSS time, the TimeSource ePRTC delivers an autonomous, secure and fault tolerant reference for time, phase and frequency synchronization.


TimeSource 3X50 ANSI shelf1

TimeSource 3550

The newly-introduced TimeSource® 3550 is a standalone Primary Reference Source (PRS) which provides Stratum 1 performance in GPS hostile environments via external wall mount or roof mounts. Its new highly integrated rubidium oscillator maintains extended holdover spec with reduced footprint.

TimeSource 3×00 can easily be upgraded to TimeSource 3550:

TimeSource 3050

The TimeSource® 3050 with a high quality Oven Controlled Crystal Oscillator (OCXO) provides your network Stratum 1 performance when locked to GPS or up to 72 hours if GPS signals are interrupted.


TimeSource 3000 (Discontinued)

TimeSource™ 3000 is a standalone office Primary Reference Source (PRS) with an integrated GPS receiver that allows your network to meet GR2830 requirements.

*Product has been Manufacturer Discontinued and Replaced by the TimeSource 3050 and TimeSource 3550

PRODUCT NOTICE: GPS Week Number Rollover in TimeSource 3×00 products


TimeCesium 4500

TimeCesium 4500

Formerly known as the PRS 45, the TimeCesium 4500 uses Cesium III beam tube technology to enable telecom network operators to generate superior and highly reliable Stratum 1 synchronization signals.


TimeCesium 4400

TimeCesium 4400

Based on the latest Cesium III technology from Symmetricom our TimeCesium™ 4400 is an autonomous Primary Reference Source designed for telecom network operators to generate superior and highly reliable G.811 synchronization signals for advanced network services.

DCD-LPR (Discontinued)

The DCD-LPR is a front-end primary reference source used in conjunction with the DCD bits clock platform for synchronizing digital telecommunications networks. The entire DCD timing platform is still a very widely utilized system and due to tight current-day budgets many of these clocks are expected to serve into the foreseeable future. Syncworks has the legacy clocking experience and surplus of parts needed to keep your system running as long as possible.

PRR-10 (Discontinued)

Originally produced by Austron, which then became Datum, the PRR-10 was and continues to be a widely deployed Primary Reference Source for digital switches. The PRR-10 is designed to provide highly reliable Stratum 1 synchronization signals. It can be used as a Stratum 1 PRS for digital switches, cross-connect systems, SONET, and SDH transmission systems. The Datum PRR-10 can be effectively used as a PRS system in small and medium-sized offices, and can successfully provide the complete timing requirements of remote sites and Controlled Enivronmental Vaults
