CALNEX BREAKS NEW GROUND IN 1588v2 TESTING

Successful 1588v2 Boundary Clock Interop and Performance Public Test

 

Amsterdam – 11 October 2011. Calnex Solutions demonstrated the successful completion of testing a 1588v2 Boundary Clock at the Carrier Ethernet World Congress event here today. The test was part of the EANTC Multi-Vendor Interoperability Test showcase at the event.

1588v2 Boundary Clocks are recognised as a vital element in delivering accurate synchronisation via Carrier Ethernet networks. This is a mandatory requirement of revenue-critical networks for application such as LTE backhaul, High-Frequency Trading and Data Centre connectivity.

The Ericsson Mini-Link SP310 was shown by the Calnex Paragon-X to deliver accurate synchronisation within the limits specified by the revenue-critical applications above.

Calnex’s Paragon-X is an all-in-one solution for validating 1588v2 clock equipment, acting as both a network emulator and a clock quality measurement tool.

In the EANTC test, the Paragon-X was placed between a 1588v2 Grand Master and the Ericsson MINI-LINK SP 310 to add network impairments. The SP310 acted as Boundary Clock, which provided clocking to an Ericsson MINI-LINK SP 110. The Paragon-X was then used to measure the 2MHz frequency and 1PPS phase stability, both recovered by the SP 110. The test results showed good interoperability and performance by the Ericsson systems.

Carsten Rossenhoevel, Managing Director of EANTC said “We are always keen to test the very latest developments in a technology and the IEEE 1588v2 Boundary Clock is such a development. The Calnex Paragon-X allowed us to measure and verify that clock performance delivered by the Boundary Clock was within the standards-based frequency and phase performance limits.”

Details of the tests and the platforms are in the Multi-Vendor Interoperability Test White Paper, which can be downloaded at www.eantc.com/cewc2011.
