Network Protocols:
Quartz model Sigma Oxo combines precision master clock technology and secure network approach with a compact modular hardware design to bring you a powerful time & frequency reference system. Applications will benefit from its extreme reliability, security, and flexibility for synchronizing critical operations. • Internal high precision time-keeping via TCXO, OCXO or rubidium oscillator. • Multiple, prioritized input time references. • Modular design with a wide variety of input/output signals supported. • High bandwidth NTP performance : Ethernet 10/100 Base-T.
• Secure network management: enable or disable protocols for encryption, authentication, authorization and accounting. • Alarms notifications via SNMP, Traps and e-mail. • Stratum 1 master clock unit as for primary reference clock (PRC).
Built in time and frequency functions are extended with up to 6 input/output modules. Included with the base unit is an extremely accurate 1PPS timing signal aligned to a 10 MHz frequency signal. Variety of option cards to add to your confi guration of timing signals, including additional PPS, 10MHz, time code (IRIG, ASCII), multinetwork NTP, and PTP outputs.
An optional multi-port NTP configuration allows for operation across 4 isolated LAN segments. For security, system management can be restricted to a dedicated management LAN. Security-hardened network appliance designed to meet rigorous network security standards and best practices. Ensures accurate timing through multiple references, tamper-proof management. Installation is aided by DHCP (IPv4), AUTOCONF (IPv6), and a front-panel keypad and display.
