Symmetricom Announces Support for ITU's New Sync-E Standard: Company Unveils Guidelines to Help Telecom Service Providers Cost-Effectively Deploy Synchronous Ethernet (Sync-E) in Next Generation Networks

Share Article

Symmetricom, Inc. (NASDAQ: SYMM), a worldwide leader in precise time and frequency technologies that accelerate the deployment and enable the management of next generation networks, today announced its support for the International Telecommunication Union's (ITU) new Sync-E (Synchronous Ethernet) standards G.8261-G.8263. The company also released a comprehensive set of materials designed to help telecommunications service providers cost-effectively deploy Sync-E in their networks.

Synchronization is one of the largely misunderstood and often overlooked aspects of network service providers in their quest for deploying next generation solutions

    "Synchronization is one of the largely misunderstood and often overlooked aspects of network service providers in their quest for deploying next generation solutions," said Frank J. Bernhard, managing principal and advisory economist for OMNI Consulting Group. "The capability to harness timing quality in the network translates to a direct return on asset (ROA) improvement for the carrier, and protection against subscriber dissatisfaction. The concentrated effort on quality of service delivered over Sync-E represents a smart business decision for those expanding their service footprint."

Sync-E is gaining interest as a cost-effective alternative to SONET/SDH as carriers transition to providing advances services, including voice, video and data applications over packet-based next generation networks. Deploying Sync-E allows an upgrade to next generation networks while driving cost out of such implementations. Symmetricom provides the cost-effective technology required to support network needs for timing and synchronization.

The second phase of standardization will be completed in the first quarter of 2008. The standard G.8264/Y.1364, distribution of timing through packet networks, will be completed in the first half of this year. Products that enable Sync-E began appearing in 2007. Symmetricom, along with other major equipment manufacturers, are actively working in ITU study groups to standardize different aspects of Sync-E to enable backward compatibility with SONET/SDH and harness the power of packet networking.

Symmetricom's newly available materials to help telecom service providers cost-effectively deploy Sync-E to support advanced services include:

-- "Preparing Your Network for Sync-E," guidelines for Sync-E deployments

-- Audio interview with Symmetricom Sync-E experts

-- Streaming Flash presentation

-- iPod video presentation
