Spectracoms Skylight System


Skylight Indoor GPS Timing System
Even though synchronizing network master clocks and time servers to GPS is well-known as the standard for the most time-sensitive applications, some data centers and critical server locations are not conducive to traditional roof-top GPS antenna installation.

Spectracom 9483 NetClock Time Server

Spectracom NetClock 9483Model 9483 NENA-compliant GPS Master Clock

The NetClock 9483 continues Spectracom's legacy of highly accurate and reliable GPS master clock technology that is easy-to-install and manage backed by NetClock's industry-leading 5-year warranty. While maintaining strict compliance to the National Emergency Number Association's (NENA) Master Clock Standard #04-002, the new NetClock has added features to support Next-Generation 911 initiatives, and has been tested against NENA’s Security for Next Generation 9-1-1 Standard #075-001.

Applications such as emergency communications centers require reliable timing to accurately synchronize networks, systems, and devices and to log events with legally traceable time. Spectracom’s NetClock Model 9483 is ideally suited for delivering worldwide, split-second timing to mission critical systems. The 9483 is the latest generation NetClock that has set the standard for the highest reliability synchronization.

Easy Set-up and Administration

The NetClock is simple to install and easy to manage. Front panel controls allow for network configuration and other set-up parameters. A full-suite of network protocols includes SNMP capability, support for enterprise directory servers to authenticate users, internal and external logging and monitoring of error messages through Syslog, DHCP for installation convenience, and IPv4/IPv6 dual stack for future network modernization. A new browser-based user interface allows for easy monitoring and configuration changes.

The Most Secure NetClock Ever

Enhanced security features meet and exceed the National Emergency Number Association (NENA) standard for the security of next-generation 9-1-1 systems. All features, interfaces, ports and protocols can be enabled and disabled based on your needs. These features include remote login and file transfer capabilities, providing the utmost security using industry standard interfaces.

A Truly Flexible Master Clock

The model 9483 offers a bridge from legacy equipment to network-based systems. In addition to network synchronization, a variety of timecodes (including all the NENA formats) and signals provide synchronization to specific devices. Precise 10 MHz and 1 pulse-per-second signals are standard, and T1/E1 signals are available for syncing telecom systems. The built-in network port, can be supplemented by an option to include 3 additional network ports that support Gigabit Ethernet for synchronizing isolated networks, or for restricting administration to a management network.

Enhanced Reliability

An integral oven-stabilized crystal oscillator (OCXO) is available to provide at least 30-days of accurate synchronization in case of loss of GPS. An optional Rubidium oscillator is available the most-critical applications. The 9483 NetClock can be ordered with integral AC or DC power, or both for redundancy.

Improve emergency response performance and record-keeping accuracy with time synchronization

Accurate time-of-day is important in communications centers and public safety answering points (PSAPs) for time stamping events. Without accurate time, different equipment and systems display and record different times. There is no certainty of start/end times for events and tasks and you are left vulnerable to potential litigation. Time synchronization with Legally Traceable Time® is critical for records accuracy and to support legal evidence in court.

  • Improves interoperability and overall operational quality
  • Prevents conflicting records and displays
  • Establishes time and event stamps as legally traceable
  • Protects your municipality against potentially costly litigation
  • Fully automated; eliminates manual errors

Saving Time. Saving Lives.

A prime focus of Public Safety is on the critical “response time” for life-threatening events such as heart-attacks – in essence suggesting that it is a matter of minutes that determine the fate of victims. Studies have shown when dispatch and other recording systems employ synchronized time, the improved records data has resulted in measurable life saving differences to their communities.
