SecureSync PTP Grandmaster

  • SecureSync master oscillator for land mobile radio

PTP Grandmaster Overview

As methods of data transfer evolve, so too does the need for increased speed in information transmission.

Precision Time Protocol (PTP), as defined by the IEEE 1588 standard, provides the most advanced method of synchronization over Ethernet networks. Spectracom supports Precision Time Protocol Version 2 (PTP v2) in its SecureSync PTP Grandmaster Clock system. The standard configuration includes up to 6 PTP ports to operate various PTP deployments, allowing for maximum scalability to handle the expansion of your network infrastructure.

  • PTP grandmaster 1 GbE port via copper and fiber optic interfaces (SFP module)
  • Industry-best ±4ns time stamp resolution (HW time stamping)
  • Better than 25 nanosecond time stamp accuracy to UTC
  • Supports default, enterprise and telecom PTP profiles
  • STL Option - add STL to GPS or GNSS input references to improve resilience, or use STL alone for indoor applications.
  • Provides multicast, unicast, and hybrid mode addressing
  • Available time code reader/ generator options
  • High bandwidth PTP performance
  • Ethernet 10/100 Base-T communications port for set-up and management
  • Other PTP configurations are available

Details

Equipped with the latest and most innovative 10/100/1000 Base-T Gigabit PTP Option Card on the market, the SecureSync High-Speed PTP Grandmaster Clock boasts industry-leading packet throughput and data processing power. The installment of an optional slave-ready 10/100 Mb PTP Option Card creates a powerful master-slave combination to satisfy even the most rigorous timing requirements.

Standard RF and fiber optic interfaces via SFP modules provide the ability to select between either of the two media relative to your specific needs, greatly reducing the effects of distance limitations within your system architecture.

Typically, applications for timing use GPS as a precise, traceable, high availability, and free source of synchronization. But GPS is not the only satellite in the sky. More and more Global Navigation Satellite Systems (GNSS) are being developed and deployed. This white paper describes the trend to multi-GNSS using the example of the Russian GLONASS system as a complement to GPS.

More Info
NTP (Network Time Protocol) and SNTP (Simple Network Time Protocol) are very similar TCP/IP protocols in that they use the same time packet from a Time Server message to compute accurate time. The procedure used by the Time Server to assemble and send out a time stamp is exactly the same whether NTP (i.e. full implementation NTP) is being used, or if SNTP is being used.

More Info
Large-scale NTP deployments require consideration for the network’s time synchronization architecture. Network time deployments are usually driven by considerations for reliability, scalability, manageability and security. The capability of modern NTP servers, such as Spectracom SecureSync® and NetClock® time servers, is such that capacity does not impact the design of the synchronization architecture.

Success Stories

More Info
Thesys Technologies solved these requirements: (1) a highly reliable and accurate GPS-source of time; (2) The ability for the GPS time server to distribute time to multiple networks and physical locations; (3) Sub-microsecond synchronization between company servers and the GPS time server; (4) Eliminate any potential backward time adjustment that was observed with a PTP client as correctly sequenced events is a must.
