It may be also used by 2G, 3G and LTE service providers which provide a time of day reference to their customers over their wireless networks. VCL-3048 locks to a GPS/GNSS reference to provide an NTP time reference on a 10/100BaseT Ethernet Port which can be used to serve various types of assets in the networks. The VCL-3048 is equipped with a highly accurate, TCXO to provided a high stability holdover clock in the event of unavailability of the GPS/GNSS antenna failure, or a temporary loss of reception in a totally isolated network without any external reference. The VCL-3048 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 transfert) capabilities. VCL-3048 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.
