SecureSync LMR Master Oscillator

  • SecureSync master oscillator for land mobile radio

The SecureSync® platform was designed for the rigors of time and frequency synchronization For Land Mobile Radio.

Simulcast systems rely on precise time and frequency to ensure the reliability of critical communications systems such as police radio. This configuration of SecureSync is a drop-in replacement for the earlier generation of Ageless® Master Oscillators (models 8194/95/97). It can be configured for the specific needs of the system.

  • Multiple, prioritized input references - GPS, PTP, internal
  • Internal precision time-keeping via OCXO or Rb oscillator
  • A wide variety of output signals supported via modularity
  • Built-in NTP server; PTP master/slave options
  • Precise frequency references for carrier accuracy
  • Synchronized CTCSS outputs
  • Configurable 1PPS offsets
  • Telecom frequency and data rate synchronization

Details

SecureSync® combines Spectracom’s precision master clock technology and secure network-centric approach with a compact modular hardware design to bring you a powerful time & frequency reference system for simulcast systems and other critical land mobile radio applications.

An important advantage of SecureSync is its unique rugged and flexible modular chassis that can be configured for your specific needs. Built-in time and frequency functions are extended with up to 6 input/output modules. Included with the base unit is an extremely accurate 1PPS timing signal aligned to a 10 MHz frequency signal without any phase discontinuity. A variety of internal oscillators (typically locked to GPS) are available depending on your requirement for holdover and phase noise.

More Info
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.

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.
