Network Timeserver with TCR synchronized time base

LANTIME (Local Area Network Timeserver) provides a high precision time base

to a TCP/IP network (Stratum-1-Server). The NTP (Network Time Protocol) is used
to synchronize all NTP clients with the reference. The several LANTIME variants
differ from each other by the time reference. A GPS receiver, a DCF77 receiver or an
IRIG time code receiver can be integrated as an internal reference as well as a
combination of these references (hybrid system). External references are also
possible. LANTIME/TCR is a set of equipment composed of a IRIG Time Code
Receiver TCR510, a single-board computer with integrated network board and a
power supply, all installed in a metal 19" modular chassis and ready to operate. A
simplified LINUX operating system is installed on the single-board computers flash
disk. Four push buttons and a 2 x 40 character LC display can be used to configure
and monitor the time server. After the network connection has been established the
time server can also be configured and monitored remotely from a workstation via
TELNET or FTP. An integrated HTTP server enables access to the LANTIME by
using an ordinary WEB browser.
