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)
