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 included 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.
