Standard time service serve

  (1) Automatically receive upstream time, gps/ Beidou time service source;
(2) 10/100m adaptive Ethernet interface with 2 independent IP addresses;
(3) VFD display screen, displaying clock source information, signal strength, time, date and data validity;
(4) Efficient Linux system, high-performance industrial motherboard, shockproof, no hard disk and fan design, stable and reliable, mtbf> 80000 hours;
(5) The client supports WINDOWS9X, windows nt/2000/xp/2003, Linux, UNIX, sun Solaris, IBM AIX and other operating systems as well as Cisco routers and switches;
(6) 1 channel PPS output, 1 channel differential B code output, 1 channel TTL B code output
These output controls need to be configured remotely through the browser;
(7) Built in temperature compensated crystal oscillator, the time error within one year shall not be less than 1 second under the condition of no time source;
(8) Management port: 10baset/100baset Ethernet interface /rj45 for management;
(9) Comply with rfc2030 (simple network time protocol (SNTP) version 4) and provide time query service to terminals on the network;
(10) Support NTP V1, V2, V3, V4, SNTP (RFC 2010), MD5 and authentication (RFC 1321) to automatically obtain the time of level-1 master clock and update the system time in the absence of satellite signal;
(11) Network time synchronization accuracy: NTP on tcp/ip network: 1-10ms;
It has the functions of data security recognition and peer-to-peer timing; The server recognizes the identity of the clock terminal through tcp/ip protocol, and the time service server time can be output if the server recognizes the identity
If the server does not recognize the identity, the clock terminal is illegal and unsafe, and the server cannot provide time service
(12) User capacity: 20000;
(13) NTP request quantity: 1000 times / S;
(14) Environmental requirements: working temperature: 0 ~ ＋ 50 ℃;
(15) Power supply voltage: 220v± 15％；
(16) Power frequency: 50hz± 5%；
(17)19‘& rsquo; 1U chassis
