Protect critical infrastructure networks

Issue 7 2021 IT infrastructure

Infrastructure communication networks – 5G mobile, utilities, cable, transportation, defence and data centres – acquire and maintain signals for precise timing from Global Positioning Systems (GPS) or other worldwide satellite constellations. These networks require redundant backup systems when Global Navigation Satellite System (GNSS) signals are unavailable.

The TimeProvider 4100 Release 2.3 precision timing grandmaster available from Microchip Technology meets this requirement with the industry’s latest IEEE 1588 v2.1 2019 security standard for protection of timing systems, while also providing an increased level of deployment flexibility and scalability.

Microchip’s TimeProvider 4100 Release 2.3 grandmaster introduces an ultra-resilient multi-client Precision Time Protocol (PTP) optional licence, providing customers with up to three connections to other grandmasters in the operator’s network. This capability can be used as a backup for time and phase input. This new option implements the latest IEEE 1588 2.1 standard majority vote mechanism to select the best input for Assisted Partial Timing Support (APTS) backup protection.

Additionally, TimeProvider 4100 Release 2.3 provides more deployment flexibility with support for two PTP server profiles on every Ethernet port. Customers can now optimise usage of these ports without additional hardware investments. TimeProvider Release 2.3 also allows PTP server, PTP client and in-band management to be used on a single port.

As a software update, TimeProvider 4100 Release 2.3 is available for new and already-deployed systems.
