Overview
The VIAVI SecurePNT EdgeGM 7000 series is an edge Grandmaster clock built into a half-19", 1U unit. It brings together timing from multi-orbit space sources and terrestrial sources with high-speed PTP Grandmaster and NTP time server functions. It is designed for critical infrastructure that must keep working through PNT disruptions, such as jamming, spoofing and meaconing attacks on GPS/GNSS antennas, and cyberattacks on NTP/PTP network timing.
TrustedPNT technology
The EdgeGM 7000 uses VIAVI TrustedPNT technology. It authenticates, verifies and qualifies multiple orbital and terrestrial timing sources, so it can switch smoothly to a trusted timing reference. The approach follows a zero-trust principle of "never trust, always verify". As GNSS backup, it can use the optional SecureTime altGNSS GEO-L or LEO-S services.
Models and ports
The series has three receiver configurations. The EGM-7000 has a multi-band GNSS receiver. The EGM-7000L adds a GEO-L receiver and the EGM-7000S adds an STL (LEO-S) receiver. All three have 8-hour holdover. The unit has six Ethernet ports for PTP and one out-of-band management port. Ports 1 and 2 run at 1/100/1000 Mbps. Ports 3 to 6 run at 1 or 10 Gbps.
Software license options
The 25G PTP Software License Option upgrades Ports 5 and 6 to 25 Gbps, in addition to 1 or 10 Gbps. The unit can then connect directly to 25 GbE networks without speed conversion. As standard, the EGM-7000 supports PTP for 256 unicast clients at the full message rate of 128 packets/second. The 1024 Client Software License Option raises this to 1024 unicast clients at the same rate.
