The Access server time synchronisation takes place via a time server in the local network or via the Internet. In this case, the DHCP options 4 and 42 configured in the Access server point to the IP address of the Access server which acts as time server (NTP/Time Server) for the Access end devices. Note: When installing the Access system on the customer’s own server hardware or virtualisation solution, the time server service (NTP/Time Server) in the server operating system must also be configured, otherwise a time server cannot be provided for the Access end devices.NTP serverNTPAccess ServerNTPAccess end devicesBenefits • Time deviation cannot arise between Access server and Access end devices. • Stable Access system operation, even if the Internet or a time server is down.
