Installing/troubleshooting RS-485 synchronized TimeView digital display clocks
When Spectracom Model TimeView® digital display clocks are synchronized via RS-485 normally, all six digits will be present, with the correct time displayed and no portion of the display will be flashing. This document provides tips on
Time Synchronization’s Role in Real-Time Trading
GPS-enabled network time synchronization enables real-time trading of financial instruments by providing secure, accurate, and reliable time for events across the trading network. When an event occurs and is logged into the realtime database, the time associated with the event is accurate to national and international time standards. Synchronizing the time at which a transaction…
Student Records—Increased Security and Authentication with Time Synchronization
Synchronizing a network to one time source immediately improves an education institution’s ability to authenticate and verify the creation and alteration of documents – critical for protecting student records. Synchronizing time across a network produces verified time stamps, on which the authenticity of digital signatures depends. The time stamp must be secure, accurate, and reliable—both…
Clock Accuracy in 911 Dispatch Centers
Accurate time-of-day is important in Public Safety Communications Centers for time stamping of event records to provide legal evidence of emergency response times in court. Spectracom’s NetClock products automatically keep all the clocks in a center running exactly on time relative to the worldwide time standards.
NTP over Anycast
Orolia NTP services, implemented in its SecureSync and NetClock 9400 platforms, are compatible with an Anycast routing scheme. The NTP over Anycast feature is a combination of the time server’s ability to associate one of its network ports to an Anycast IP address and to remove itself as an available time source if there is…
Differences Between NTP and SNTP
NTP (Network Time Protocol) and SNTP (Simple Network Time Protocol) are very similar TCP/IP protocols in that they use the same time packet from a Time Server message to compute accurate time. The procedure used by the Time Server to assemble and send out a time stamp is exactly the same whether NTP (i.e. full…
Routing of Data Across Multiple Networks
This technical note provides a general description of the software routing scheme of a single Spectracom unit with multiple network ports and offers alternative timing hardware deployments if software isolation is insufficient.
Email Notification Setup for SecureSync and NetClock 9400
This document is designed to help you configure Email Alerts to generate automatic emails when certain events occur on an Orolia time server with 5.1.x software.
