NTP server operation
The GPS Network Time Server is a level 1 time server, according to the definition of time
broadcasting and synchronization given in the NTP recommendation.
It operates in conformance with the NTP version 3 described in recommendation RFC 1305.
It delivers time information over the network in the server mode, only in response to client
polling. It supports communication through routing networks. It handles selection of up to
five bridges connecting its local network to other networks.
When the system maintains a UTC time acquired by synchronization on GPS, the information
broadcast over the network is identified as broadcast level 1. Such information is maintained
as long as the clock is locked on information reception from GPS satellites.
A loss of locking is indicated by the "LOCKED" indicator going red, the broadcast NTP level
is 16, which indicates that the message or its synchronization is invalid.
When locking is restored, the server automatically returns to level 1.
Control is fully automatic.
The addresses of the bridges and adjacent networks can be entered via the remote control
interface. A specific sub-menu is provided in the GPSNTSTP software.
