By Andreja Jarc. The timing industry is anxiously waiting for the unavoidable Leap Second Insertion which is announced for this year on June 30, 2015 at UTC midnight. The Leap Second has been introduced by The International Earth Rotation Service … [Continue reading]
By Andreja Jarc. Introduction Meinberg LANTIME servers with a fw 6.17.004 or higher are enhanced with a new NTP monitoring feature. This feature enables monitoring of NTP performance of up to 100 external NTP nodes (servers and clients) attached in … [Continue reading]
Five Minute Facts About Packet Timing By Doug Arnold. The IEEE Standard for Synchrophaser Measurements for Power Systems (IEEE C37.118.1 -2011) recommends that phase measurement equipment in power systems by synchronized to UTC to within 1 μs. … [Continue reading]
By Andreja Jarc. At this time I will grant you a short summer break from all the theory :-) and we will do some hands-on refreshment instead! Let’s check if PTP messages between a GM (Grandmaster) and a slave clock both configured with the Default … [Continue reading]
By Andreja Jarc. In my last post I promised to show you how to configure the IEEE 1588 Default Profile on a grandmaster (GM) via a web interface. This is what we will do right now. We will use the same PTP master device M600/GPS/PTP from … [Continue reading]
By Andreja Jarc. The theory on IEEE 1588 PTP its functions and features have been extensively covered in our previous blog posts. To refresh your knowledge you can refer here. As you may have noticed the PTP environment is exceptionally complex due … [Continue reading]
Five Minute Facts About Packet Timing By Doug Arnold. The Precision Time Protocol Telecom Profile for Frequency Synchronization was created by International Telecommunication Union, or ITU, for the transferring precise frequency through a … [Continue reading]
By Andreja Jarc. Finally good news on the subject of measuring asymmetric delays in LAN and WAN networks using packet timing technologies. Meinberg Radioclocks provides a reliable solution for measuring asymmetry in NTP as well as IEEE 1588 PTP … [Continue reading]
Five Minute Facts About Packet Timing By Doug Arnold. So far in this column we have talked about multicast PTP. Multicast is clearly critical to the working of the standard Best Master Clock Algorithm, since all the clocks need to discover who the … [Continue reading]
By Andreja Jarc and Doug Arnold. The Simple Network Managment Protocol Most network connected devices support a number of management options including the Simple Network Management Protocol, or SNMP. SNMP is a network protocol which allows a single … [Continue reading]
