Timelink has developped a solution for delivering time to citical network based on two equipements.
One equipement within the open world synchronizes through NTP and transmits time via IRIG-B protocol.
The other equipement within the secured world synchronizes through IRIG-B and transmits time via NTP
to the clients. This solution is typically used by banking systems preventing attacks thanks to the protocol break.
TMS2011 is the server connected to the open world and transmits IRIGB time code based on NTP information.
TMS2010 is the client connected to the secure network, receiving IRIGB time code and acting as a NTP server to the network.
