Accedian Networks^™— the number one provider of High Performance Service Assurance^™ solutions for Carrier Ethernet mobile backhaul networks, and Symmetricom®, Inc. (NASDAQ:SYMM) – a worldwide leader in precision time and frequency technologies, today announced Accedian’s participation in Symmetricom’s SyncWorld™ Ecosystem Program. The program was launched earlier this year to support precise timing and synchronization requirements for 4G LTE deployments that ensure seamless integration for service provider networks.

To qualify as a member of SyncWorld, Accedian Networks conducted detailed interoperability testing to validate synchronization distribution scenarios leveraging Symmetricom’s carrier-class Timesource^® 3000 NTP server as the Accedian NTP client in its High Performance Service Assurance platform consisting of the EtherNID^®, MetroNID^® and MetroNODE 10GE™ demarcation and OAM aggregation devices.

“Accurate timing and precise synchronization in mobile backhaul networks is critical to measuring and maintaining QoS and performance as mobile users travel between cell sites,” said Craig Easley, V.P. of Marketing and Product Management at Accedian Networks. “By combining Symmetricom’s world-leading precision time and frequency technologies with Accedian’s Ethernet demarcation devices, we can jointly deliver a fully-interoperable solution that includes the timing and synchronization services required to support the rapid deployment of 4G LTE networks.”

“One-way delay measurement relies on carrier grade synchronization,” said Manish Gupta, vice president marketing at Symmetricom. “We’re delighted to welcome Accedian Networks to SyncWorld so operators can benefit from these performance metrics using many synchronization technologies including NTP, GPS, SyncE and IEEE 1588.”
