Symmetricom Deploys PackeTime® Systems Enabling IEEE 1588v2 Precision Time Protocol In More Than 150 Networks Globally

SAN JOSE, Calif., June 11, 2012 /PRNewswire/ --  Symmetricom®, Inc. (NASDAQ: SYMM), a worldwide leader in precision time and frequency technologies, today announced that it has deployed its PackeTime® Systems providing IEEE 1588v2 Precision Time Protocol (PTP) in more than 150 networks worldwide. This milestone demonstrates strong momentum for IEEE 1588 as the standard for distributing synchronization for operators and carriers over Ethernet network infrastructures. Symmetricom has supported 50+ deployments in 2012 since it had announced the 100 deployment mark in October 2011.

IEEE 1588 is a synchronization protocol developed for IP-based networks that delivers both frequency and phase synchronization, and is being deployed to support carriers worldwide transitioning their networks to Ethernet backhaul. According to Heavy Reading's Ethernet Backhaul Quarterly Tracker Service published March 2012, IEEE 1588 is expected to be the primary synchronization solution in over 1 million Ethernet cell sites by 2015.  Symmetricom is working with key industry players such as Nokia Siemens Networks, an early adopter of IEEE 1588, to deploy and develop PTP technologies. Nokia Siemens Networks has already deployed the standard in more than 80 networks.

"Rollouts of IEEE 1588 have definitely picked up as more carriers move to Ethernet backhaul," said Giuseppe Targia, head of MBB Packet Networks product management, Nokia Siemens Networks. "Precise timing and synchronization within the network are critical to operations, and our partnership with Symmetricom has enabled a reliable migration to packet based infrastructure."

To further support the adoption of IEEE 1588 and next generation networks, Symmetricom's SyncWorld® Ecosystem Program is enabling interoperability and cooperation among members of the mobile ecosystem to ensure seamless integration to service provider networks.  Nokia Siemens Networks was a founding member of the SyncWorld Ecosystem Program launched in March 2011.

"IEEE 1588 is becoming a key synchronization standard as networks transition from TDM to packet-based to support 4G/LTE network requirements," said Manish Gupta, vice president of marketing and business development for Symmetricom. "We see this trend continuing and we look forward to supporting the transition with a comprehensive portfolio of IEEE 1588 solutions."
