Eight Port PTP Grandmaster Clock

The PTP-8080 is a GPS Network Time Server (NTS) for NTP or PTP IEEE 1588 that provides secure, accurate and reliable time synchronization for networks and offers integrated fully managed switch capabilities for 8 (10/100/1000BASE) Gigabit Ethernet ports. The PTP-8080 can be used for data centers, test facilities, military installations, federal or municipal agencies, financial services and technology firms, and many other enterprises which need precision timing to support their network operations.

(*) Accuracy per network hop.

The PTP-8080 provide exact time over Ethernet either based on the well-established NTP/SNTP protocol or PTP according to IEEE 1588 Std 2008. It not only provides NTP and PTP timing capabilities, but also a variety of other time codes and signals, such as GPS emulation and IRIG-B. The unit also provides backwards compatibility for older timing systems. Such interfaces are normally provided on the network boundaries integrated on relevant SNTP clients or PTP Slave Clocks platforms.

The PTP-8080 is used for applications that require reliable timing to accurately synchronize networks, systems, and devices and to log events with legally traceable time. The PTP-8080 Series offers a broad portfolio of features, including network master clocks (NTP or PTP), monitoring and management capabilities, and a complete software package to deliver high performance timing for network applications and devices. The PTP-8080 is easy-to-install and is full configurable to customize its features, interfaces, ports and protocols to your needs. These features include remote login and file transfer capabilities, which provide the utmost security using industry standard interfaces. A full-suite of network protocols includes SNMP capability, support for enterprise directory servers to authenticate users, internal and external logging and monitoring of error messages through Syslog, DHCP for installation convenience, and IPv4.

The PTP-8080 is a reliable and accurate NTP and PTP Grand Master Clock fulfilling the IEEE 1588 Std 2002 (v1) and IEEE 1588 Std 2008 (v2). The PTP-8080 contains a built-in state-of-the-art GPS receiver that is used as the time base for the GMC clock. The PTP-8080 platform supports 2-step clock modes and either E2E or P2P as the delay mechanism. This means that all possible PTP profiles can be supported. The platform maximizes PTP performance since all critical PTP functions are implemented in hardware. The switch functionality in the PTP-8080 series offer full management based on HTTP, telnet, CLI or SNMP. Network Redundancy is achieved based on the NSTP protocol. The unit offers a wide operating temperature range: [-40°F to 158°F] / [-40°C to 70°C].
