GPS / GNSS Time Servers
GPS Receiver and Time Distribution Unit

VCL-3086 is equipped with a highly accurate, TCXOto 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 systemmanageability. Other features include DHCP for installation convenience and support concurrent IPv4/IPv6 networks to provide NTP time and frequency synchronization.

Performance:

The VCL-3086 provides a 10/100 BaseT Industrial Ethernet NTP Port that meets and complies with EN61000-4-5 Level 3 specifications making it suitable for the equipment to be installed in harsh industrial environments which include Electric Sub-Stations, Railway and Metro Networks. VCL-3086 is capable of servicing up to 3,000 NTP requests per second.

Monitoring and Management:

The VCL-3086 can be managed by Graphical User Management Interface. A text based and menu driven setup utility is also available via Telnet or SSH. An optional Graphical User Network Management Interface (NMS) allows multiple systems installed on a network to be monitored and configured from a single or multiple management locations.
