Service DescriptionJuniper NetworksTCA8000 and TCA8500 Timing Servers are primary reerence

sources that provide highly accurate timing that is critical or mobile networks. Based on

IEEE1588-2008 Precision Time Protocol (PTP), these servers provide time distribution

across IP and legacy inrastructures to numerous timing clients. These appliances

implement hardware based time stamping to provide wirespeed PTP with unparalleled

accuracy, while decreasing vulnerability to distributed denial-o-service (DDoS) attacks.

The TCA8000 line o timing servers use GPS and a local oscillator to deliver Stratum 1

timing reerence and exceptional holdover.

Because they are an integrated platorm, the TCA8000 line replaces previous generations

o equipment at a lower total cost o ownership. The network timing distribution

capabilities o the TCA8000 line reduces the need or expensive Cesium timing elements

in the network. The TCA8500 has a Rubidium internal oscillator or standalone or central

oice deployments. TCA8000 and TCA8500 appliances represent industry irsts such asITU Stratum clocking over IP networks and IP-based redundancy.

Service Overview

TCA8000 and TCA8500 Timing

Servers are 19-inch rack-mountable

Primary Reerence Source (PRS)

and Primary Reerence Clock

(PRC) that provide superior time

stamping accuracy and redundant

conigurability. The TCA8000 and

TCA8500 accept a GPS signal rom

a variety o manuacturers antennas,

and provide antenna power via an

attached radio requency (RF) cable.

These servers accept a timing signalrom timing sources such as GPS, or

BITS. The TCA8000 and TCA8500

provide superior hardware-based time

stamping accuracy and redundant

configurability.
