The CoBox Network Time Servers are compact and stand-alone devices which can
receive standard world time information from a GPS source and make that timing
information available to other network nodes. Each CoBox Network Time Server
supports NTP and time/udp protocols for communicating time information to
other devices. Models supporting Ethernet or Token Ring are available.
