NetClock 9483 Overview

The NetClock 9483 has been designed specifically for these environments, and when using GPS as its timing reference, the UTC (Coordinated Universal Time) time standard is employed, thus allowing the NetClock 9483 to provide legally traceable time and frequency synchronization services for various related environments and equipment, such as the following:

    • 9-1-1 and PSAP communication center telephony
    • Computer network synchronization
    • VOIP/voice and video recording
    • CAD
    • ANI/ALI controllers
    • Radio consoles and communications equipment
    • Display clocks
    • Security & building access systems, fire alarm systems

The NetClock 9483 also includes backwards-compatibility support with all previous generation NetClock products; thus providing a bridge from legacy devices and equipment to network-based systems.

The NetClock 9483 series is a truly flexible Time Server/Master Clock, which in addition to providing highly accurate network time synchronization, also supports a variety of timecodes (including all NENA formats) and signals to synchronize specific devices. The built-in network port can be supplemented to include 3 additional Gigabit Ethernet (10/100/1000Base-T) ports for synchronizing isolated networks, or for restricting administration to a specific management network. Precise 10-MHz and 1-Pulse-per-second (1PPS) signals are standard features, and additional optional features include support for T1/E1 signals are available for synchronizing telecom systems and equipment, and Precision Timing Protocol (PTP) I/O support.

The unit is housed in a 19” rack unit chassis and offers an integrated power supply. DC power is available as back-up to AC power, or as the primary input power source.

Note: All features described are not available on all NetClock 9400 Series variants.

Initial setup of the NetClock 9483 can be done via its front panel serial port interface, and further management and configuration can be performed via NetClock’s Web-based user interface.

NENA Standards Compliance & Support

The NetClock Model 9483 is designed to meet or exceed the following NENA standards and criteria:

    • NENA PSAP Master Clock Standard #04-002
    • NENA Security for Next-Generation 9-1-1 Standard (NG-SEC) #75-001

Note: Information regarding the configuration of the NetClock’s NENA module can be found under NENA-Compliant Module.

Security Enhancements

In addition to fully supporting the NENA Security Standard #75-001, the NetClock 9400 series are security-hardened network appliances designed to meet rigorous network security standards and best practices. They ensure accurate timing through multiple references, tamper-proof management, and include extensive logging capabilities for auditing purposes. All features, interfaces, ports, and protocols can be enabled or disabled based on your network policies.
