Vitesse recently reported network performance results to the ITU-T documenting VeriTime’s under 3ns per hop accuracy over a nine-hop IEEE1588v2 Transparent Clock (TC) network, making it the industry’s only solution that fulfills TD-LTE and LTE-Advanced requirements in real-world tests today, according to the manufacturer. Network equipment OEMs now have a viable upgrade path for IEEE1588v2 with the SynchroPHY and other VeriTime-enabled solutions. Vitesse’s IP Edge portfolio, comprised of Carrier Ethernet Switch Engines and the SynchroPHY family, enables the industry’s highest accuracy, all-hardware IEEE1588v2 implementation, critical for 4G/LTE/LTE-Advanced (LTE-A) mobile network deployments. This low-cost upgrade is achievable simply by replacing existing PHYs with Vitesse’s SynchroPHY devices, with minimal or no other changes to the rest of the system. The SynchroPHY family enables sub-10 nanosecond accurate timing through a simple upgrade of PHYs in existing routers and switches. The SynchroPHY portfolio includes the VSC8572/VSC8574 dual/quad 1GE PHYs, the VSC8487-15/VSC8488-15 single/dual 10GE PHYs and the VSC8492/VSC8494 dual/quad universal or 10GE OTN PHYs.

Vitesse’s carrier-specific Ethernet IC portfolio is fully standards-compliant and interoperable with other solutions like Boundary Clocks (BC) and software filtering solutions.
