1、The demand of center time synchronization
The requirements of party A server can provide unified time clock scheme for the 4 network system, 4 network systems including gold company server network system, server city network system, the third party payment network office OA server system and network center.

2、Solution
Based on the actual situation, choose our SNTM3015 series time device to be the main standby time source, supporting SET2000 synchronization software, with NTP network to other computer system provides millisecond time accurate to sign, at the same time to pulse, IRIG-B, serial message format, the distribution of real time intelligent protection equipment test. When the SET2000 software for the 4 network to provide on-time service, so you need a 4 port network server, virtual machine implementation plan.

Main standby clock is placed in the two computer room, each other in the way of IRIG-B signal redundancy connection (fiber channel), when the main clock failure can be switched to the standby clock. Device with GPS signal as a reference, when the GPS signal is lost, the IRIG-B signal is received, if the first two lost, the rubidium punctual module keeps the high precision self walking time. At the same time provide NTP, pulse, B code, message and other formats of time signal. (the network system to NTP way to get the time).
