GENERAL INFORMATION
1.1 INTRODUCTION
1.1.1 This manual provides the user of the NTS-100 Network Time Server all of the
information necessary to properly install, operate and utilize its features.
1.1.2 The information in this manual includes any normal maintenance and adjustment data
that may be required to facilitate field repairs.
1.1.3 The purpose of the Model NTS-100 is to provide Internet Protocol (IP) network time
synchronization, over Ethernet connected networks, via the Network Time Protocol
(NTP) developed by Dr. David Mills at the University of Delaware. In providing this
synchronization, the NTS-100 operates as a “server”. The NTS-100 currently supports
versions 2.0, RFC 1119 and 3.0, RFC 1305 of the NTP, as well as the Simple Network
Time Protocol (SNTP), RFC1361. In addition, the NTS-100 will respond to TIME
protocol requests, RFC868. Refer to Appendices A and B of this manual for details
regarding these protocols.
1.1.4 The NTS-100 obtains its timing information from one of four synchronization source
options: User 1PPS, User IRIG-B, Internal GPS, or the Automated Computer Time
Service (ACTS).
1.1.5 In addition to performing the functions of an NTP Server, the NTS-100 provides optional
timing and frequency outputs whose accuracy’s are commensurate with the
synchronization source being input to the NTS-100. These optional outputs include
1PPS, IRIG-B and 10MPPS.

This one year Limited Warranty does not apply to any software or to any product not

1.2.2 If on-site warranty repair or replacement is required, the customer will be charged the
then current field service rate for portal-to-portal travel time plus actual portal-to-portal
travel charges. There is no charge for on-site warranty repair labor.

peripherals, options) are warranted for 90 days, or longer as provided by the original
equipment manufacturer, from date of shipment.

express or implied, of merchantability, fitness for purpose or of any other kind or
