INTRODUCTION
Welcome to the NTS 03-G+ user manual! This document contains everything you need to know
about the key features, hardware, and installation process for the NTS 03-G+.
Product Overview
The Network Time Server 03-G+ (NTS 03-G+) is a precision time reference with multiple
independently addressed Ethernet ports and optional high drive IRIG-B outputs.
The NTS 03-G+ has three Ethernet ports and two alarm ports on the base unit with two
different optional expansion options:
•
Expansion 1 (6 port expansion) - Three additional Ethernet ports and two alarm ports
•
Expansion 2 (4 port expansion) - One additional Ethernet port, two alarm ports, four DC
IRIG-B (copper or fiber) and two DC/AM IRIG-B ports.
The NTS 03-G+ can be ordered with no expansion (NTS 03-G+ 3 port), or with either of the
expansion options above (NTS 03-G+ 4 port, NTS 03-G+ 6 port).
Hardware
All NTS 03-G+ Ethernet ports can function as Stratum 1 (NTP) and Grandmaster (PTP) sources.
Each unit has a built-in GPS/GLONASS synchronized master clock which provides the reference
time used by all Ethernet ports. In addition, the NTS 03-G+ can be fitted with either a high
precision OCXO or Rubidium oscillator, which increases holdover from hours to days.
With a dual redundant power supply option (not just dual power input connectors), the NTS 03-
G+ product is ideally suited for use in industrial environments and can provide NTP and PTP
server functions to multiple independent Ethernet networks.
Front Panel
The NTS 03-G+ features a front panel display (see Figure 1), giving visual feedback about the
time data being generated on the outputs. LED indicators provide “at a glance” status
information.
