1.1 Getting Started
1.1 Getting Started
Welcome to the NetClock User Reference Guide.
Where to start:
First-time users: "Introduction" below.
Users with some knowledge of Time and Frequency Servers: "Overview" on page28.
If your unit is up and running and you want to change a setting: "MANAGING TIME"
on page145, or "SYSTEM ADMINISTRATION" on page223.
1.2 Introduction
The NetClock®9400 Series combines Spectracom’s precision Time Server/Master Clock tech
nology and secure network-centric approach with a compact modular hardware design to
bring you a powerful time & frequency reference and synchronization system at the lowest cost
of ownership.
The NetClock 9400 product series is ideally suited for a variety of communications applic
ations such as Emergency Communications Centers that require extremely accurate timing and
frequency synchronization for their mission-critical systems, networks, and devices. The NetC
lock 9400 product series consists of two variants: The model 9483 is fully compliant with the
National Emergency Number Association (NENA) master clock standard, and the model 9489.
1.3 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 syn
chronization services for various related environments and equipment, such as the following:

CHAPTER 1 • NetClock User Reference Guide Rev. 16
1.3 NetClock 9483 Overview
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 networkbased 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 vari
ants.
Initial setup of the NetClock 9483 can be done via its front panel serial port interface, and fur
ther management and configuration can be performed via NetClock’s Web-based user inter
face.
1.3.1 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" on page348.

1.4 NetClock 9489 Overview
1.3.2 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 stand
ards 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.
1.4 NetClock 9489 Overview
Spectracom’s NetClock Model 9489 delivers the same high precision timing benefits of the
NetClock 9483, and is ideally suited for delivering highly precise NTP timing for syn
chronizing systems, devices, and other communications equipment and devices.
In addition to providing a secure, high precision NTP platform, NetClock 9489 also provides
one (1) 1PPS output, two (2) RS-485 outputs, and (1) RS-484 input.
There are a number of commonly shared features between both the NetClock 9483 and 9489
models. However, the NetClock Model 9489 is designed to function primarily as an NTP
server, and therefore is somewhat less complex than the NetClock Model 9483. Also, NetClock
9489 is not fully compliant to NENA master clock technical requirements. As such, a majority of
this document applies to the NetClock Model 9483, except where otherwise noted.
1.5 Inputs & Outputs
Spectracom NetClock provides multiple outputs for use in networked systems and devices. GPSequipped NetClocks can track up to thirty-two GPS satellites simultaneously and synchronize to
the satellite’s atomic clocks. This enables NetClock-equipped computer networks to synchronize
all elements of network hardware and software over LANs or WANs – anywhere on the planet.
