INTRODUCTION

nnnn

Symmetricom is the world's leading supplier

nnnn

of telecommunication and commercial

nnnn

Cesium synchronization and timing products.

nnnn

The Cesium III beam tube technology, pio-

nnnn

neered by Symmetricom, is now part of the

nnnn

TimeCesium™ 4-500 product (formerly known

nnnn

as the PRS 4-5). It is designed for telecom

nnnn

network operators to generate superior and

nnnn

highly reliable Stratum 1 synchronization

nnnn

signals for advanced network services.

nnnn

PLUG & PLAY IN < 45 MINUTES

nnnn

The TimeCesium 4-500's architecture uses the

nnnn

latest digital technology to provide superior

nnnn

performance and maintenance-free opera-

nnnn

tion. The TimeCesium 4-500 is easy to install

nnnn

and is fully operational in less than 45 min-

nnnn

utes. Its plug & play architecture provides

nnnn

highly reliable operation over the lifetime of

nnnn

the system.

nnnn

NETWORK APPLICATIONS

nnnn

The TimeCesium 4500 is used to equip core

nnnn

network offices with Stratum 1 synchronization.

nnnn

The deployment of TimeCesium 4500 sources

nnnn

across the network provides the following

nnnn

benefits:

nnnn

• Flattens the sync distribution hierarchy

nnnn

• Lowers the overall OAM&P (Operation,

nnnn

Administration, Maintenance &

nnnn

Provisioning) costs

nnnn

• Reduces the number of network recovery

nnnn

clocks (TSG/SSU) operating in tandem

nnnn

• Minimizes pointer adjustments caused by

nnnn

"frequency errors" in the SONET/SDH

nnnn

payload

nnnn

• Prevents up-stream network clock errors

nnnn

from propagating across the network

nnnn

• Enhances overall network performance

nnnn

• Provides total control of network synchro-

nnnn

nization source

nnnn

STANDARDS COMPLIANCE

nnnn

The TimeCesium 4500 meets industry stan-

nnnn

dards, including ITU-T, ETSI, ANSI, Telcordia,

nnnn

NEBS, and CE/AS.
