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.
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
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.
Choose from a variety of configurable option cards each with a variety of input/output timing signal types and quantity, including 10 MHz, 5 MHz, synchronized CTCSS, additional 1PPS, time code (IRIG, ASCII, HaveQuick), other frequencies (1.544 MHz, 2.048 MHz), telecom T1/E1 data rates, multi-network NTP, and PTP. Modules can be installed to meet your exact requirements.
To support time synchronization, SecureSync supports the latest features of precision time protocol (PTP, IEEE-1588v2) and network time protocol (NTP).
The unit can be powered by AC, or DC, or AC with DC as backup.
SecureSync is a security-hardened network appliance designed to meet rigorous network security standards and best practices. Features can be enabled or disabled based on your network policies. Installation is aided by DHCP (IPv4), AUTOCONF (IPv6), and a front-panel keypad and display.

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.

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.
