5.26.2009

The Model EC20S is the latest generation of the industry-standard Epsilon Clock™

ROCHESTER, NEW YORK and LES ULIS, FRANCE — Spectracom, a company of the Orolia Group (NYSE Alternext Paris – FR0010501015 – ALORO), announces the availability of a new GPS Clock to synchronize digital broadcast signals to improve quality of service and support efficient spectrum utilization for broadcasters of digital television and radio, and other communication transmissions. The Model EC20S is the latest-generation Epsilon Clock the standard in the industry for high performance and reliability.

Synchronization plays a critical role in the reliable operations of digital broadcast deployments, particularly for single frequency networks (SFN) where all transmitter sites use the same frequencies. For each instant in time, every transmission needs to broadcast the same digital data at the same exact frequency. Epsilon Clocks provide the signals required to synchronize the time and frequency throughout the transmission network.

The EC20S is a GPS-based turnkey synchronization solution that offers the lowest-cost of ownership. New features include an increased number of synchronization signals (7 each for timing and frequency, expandable to 10 each) allowing to mutualize synchronization over several transmitters on the same site, improved network management tools for ease-of-use, including SFN compliance monitoring, and a unique signal squelching function for reliability.

Spectracom business development VP, Emmanuel Sicsik-Pare said, “The transition from analog to digital terrestrial TV everywhere on the planet, the increasing demand for new services, and the need for better spectrum efficiency require improved synchronization systems to meet the requirements of standards such as DVB-T/S/H, ISDB-T, T/H-DMB, FLO, and DAB and DRM”. The EC20S is also well-suited for wireless synchronization of base transceiver stations for WiMax, CDMA, and TD-SCDMA. Mr. Sicsik-Pare continues, “We understand the needs of these standards for the success of terrestrial, satellite, mobile, and other new wireless communications systems”.

The Model EC20S Epsilon Clock joins the EBO3 Epsilon Board OEM, EC1S Epsilon Clock Module, and the EC22S Redundant Epsilon Clock in the most complete line-up to support network operators, transmitter manufacturers, and system integrators alike.
