INTRODUCTION
The TimeCesium™ 4400 is an autonomous
Primary Reference Source based on the latest
Cesium III technology from Symmetricom. It
is designed for telecom network operators
to generate superior and highly reliable G.811
synchronization signals for advanced
network services.
PLUG & PLAY IN < 45 MINUTES
The 4400’s architecture uses the latest digital
technology to provide superior performance
and maintenance-free operation. The 4400
is easy to install and is fully operational in
less than 45 minutes. Its plug & play architecture provides highly reliable operation
over the lifetime of the system.
NETWORK APPLICATIONS
The 4400 is used to synchronize core network
offices, which are equipped with TSG/SSU
recovery clocks – also known as BITS
concept clocks.
The deployment of TimeCesium 4400
sources across the network provides the
following benefits:
• Flattens the sync distribution hierarchy
• Lowers the overall OAM&P (Operation,
Administration, Maintenance &
Provisioning) costs
• Reduces the number of network recovery
clocks (TSG/SSU) operating in tandem
• Minimizes pointer adjustments caused
by “frequency errors” in the SONET/SDH
payload
• Prevents up-stream network clock errors
to propagate across the network
• Enhances overall network performance as
TSG/SSU’s sync rearrangements due to
clock failures are minimized through sync
status messaging (SSM)
• Provides total control of your network
synchronization source
