Sync-E 1588v2 E1/T1/ToD MPLS-TP NTP CES OAM

As Ethernet sweeps in to address the huge capacity expansion requirements for mobile backhaul, it brings completely new methods of synchronisation. Network performance depends on proving overall synchronisation quality and probing its underlying packet-layer and physical layer mechanisms. Calnex Solutions’ range of Paragon test sets are the definitive testers for Sync-E, 1588v2 PTP and NTP synchronisation mechanisms as well as E1/T1/ToD sync interfaces and Ethernet OAM. Now, the Paragon-m brings together all the measurements you need for field deployment and troubleshooting test on Ethernet backhaul synchronisation.

As in all telecoms technologies, the successful deployment of Sync-E and PTP/NTP depends on rigorous standards to allow interworking and satisfactory network performance. It’s therefore vital to measure in accordance with those standards at all interface points in the network, in particular, correlating measurements from the packet and recovered timing domains. And because today’s standards will evolve to include

Calnex Paragon emulates live network

Capture delay profiles from live Mobile Backhaul networks and replay the same profiles back in the lab

Capture and analyse PDVs then store the delay profile

Field teams using the Paragon-m can send their test files back to their labs or to the system vendors. In the lab, these same files can be replayed on the Calnex Paragon or Paragon-x platform to reproduce exact network conditions for precise troubleshooting.
