VCL-3086, IRIG-B to NTP Time Server
The VCL-3086, IRIG-B to NTP Time Server is designed to provide an NTP time source that is locked to a IRIG-B input reference to provide NTP / SNTP time synchronization to private networks such as Railways and Metro (ticketing and platform) networks, Airports and Air-Traffic Control facilities, Electric Sub-Stations, Power Distribution and Transmission companies, Oil and Gas Utilities, ISPs, Cable TV and Campus networks that are required to maintain a complete isolation from public networks for security reasons.
VCL-3086 locks to an IRIG-B (Un-Modulated IRIG-B 004) input to provide NTP time output on a 10/100BaseT Ethernet Port which can be used to serve various types of NTP / SNTP clients / slaves in the network.
VCL-3086 is equipped with a highly accurate, TCXO to provide a high stability holdover clock in the event of unavailability of the Input IRIG-B signal failure, or temporary loss of reception in a totally isolated network.
VCL-3086 provides remote management and monitoring facility with a password-based access using SSH as well as MD5 authentication to ensure operational reliability and security. Additional features include remote login and remote firmware upgrade (file transfer) capabilities.
VCL-3086 includes complete SNMP monitoring as well as support for enterprise directory services for user authentication, internal and external logging and monitoring of alarm and error messages through Syslog ensures a high level of system manageability.
Other features include DHCP for installation convenience and support concurrent IPv4/IPv6 networks to provide NTP time and frequency synchronization.
