DATASHEET TCA8000 and TCA8500 Timing Servers Product Overview Juniper Networks TCA8000 and TCA8500 Timing Servers are 19-inch rack-mountable Primary Reference Source (PRS) and Primary Reference Clock (PRC) that provide superior time stamping accuracy and redundant configurability. The TCA8000 and Product Description Juniper Networks® TCA8000 and TCA8500 Timing Servers are primary reference sources that provide highly accurate timing that is critical for mobile networks. Based on IEEE1588-2008 Precision Time Protocol (PTP), these servers provide time distribution across IP and legacy infrastructures to numerous timing clients. These appliances implement hardware based time stamping to provide wirespeed PTP with unparalleled accuracy, while decreasing vulnerability to distributed denial-of-service (DDoS) attacks. The TCA8000 line of timing servers use GPS and a local oscillator to deliver Stratum 1 timing reference and exceptional holdover. TCA8500 accept a GPS signal from Because they are an integrated platform, the TCA8000 line replaces previous generations a variety of manufacturers’ antennas, of equipment at a lower total cost of ownership. The network timing distribution and provide antenna power via an capabilities of the TCA8000 line reduces the need for expensive Cesium timing elements attached radio frequency (RF) cable. in the network. The TCA8500 has a Rubidium internal oscillator for standalone or central These servers accept a timing signal office deployments. TCA8000 and TCA8500 appliances represent industry firsts such as from timing sources such as GPS, or ITU Stratum clocking over IP networks and IP-based redundancy. BITS. The TCA8000 and TCA8500 provide superior hardware-based time Features and Benefits stamping accuracy and redundant Features congurability. • Hardware-based time stamps • 100 Mbps wire speed PTP processing • Variety of antenna voltage outputs • Integrated web server • Telnet, SNMP, and MIB support • 10/100BASE-T Ethernet interfaces • OCXO or Rubidium oscillator options Benets • Ease of use • Lower OpEx • Reuse of existing antenna • Nanosecond timestamp accuracy • Storage backup and scheduling • Impervious to DoS attacks 1
