The challenges of delivering the PTP telecom profile with the required accuracy are important in Ethernet / MPLS networks. There is also a renewed interest in time testing for both network commissioning and troubleshooting.
SONET / SDH and Ethernet serve different purposes in the realm of telecommunications, and each has its own advantages and disadvantages. While Ethernet has become the dominant technology SONET / SDH continues to be utilized in certain scenarios.
GNSS is not only critical for verifying the accuracy of protocols such as PTP, SyncE, IRIG-B, 1PPS or NTP, but it is also required for one-way delay (OWD) measurements with two testers and for generating transmission and timing protocols.
Counts, statistics, LEDs provide info about the events and how they were recorded, but they do not say much about how they are distributed in time. This information provides the logger with a representation to track the evolution of key parameters.
The use of Ethernet, MPLS, and IEC-61850 in power grid networks enables the deployment of robust and scalable infrastructures, as well as the use of standard protocols that facilitate interoperability, control, and service efficiency.
MPLS is considered a reliable and efficient technology for supporting mission-critical applications as it provides a mechanism for efficient packet forwarding,allowing for the creation of virtual private networks (VPN)
Controlling jitter in E1 and T1 lines is required for maintaining the reliability, accuracy, and quality of digital communication ensuring proper synchronization, data integrity, and performance in timing, voice and data applications.
One-Way Delay test is important for verifying IEEE C37.94-compliant teleprotection systems because it directly assesses critical aspects such as timing, fault response, coordination, compliance with standards, and overall network reliability.
Round Trip Delay test over C37.94 is critical in teleprotection applications, where timely and accurate message communication is essential for the proper operation of protective relays and the quality of the power service.
This test involves introducing simulated disturbances into the C37.94 channel to assess how the teleprotection can handle adverse conditions as it can be subject to signal distortion, noise, interference, and other that can affect its reliability.
The Through Mode test is performed to ensure that the communication equipment correctly supports the C37.94 standard, allowing data to pass through without being processed; the xGenius or Zeus tester verifies that this functionality works correctly.
