| Abstract: |
| In order to analyse the effect of the switch technology on time unific
ation system, the structure and signal process of time unification system using
centralized switch technology and distributed switch technology are given,t
he reliability models of frequency signal and time-code signal based on the two
switch technology are established,and the reliability is computed respectively.T
he results show that distr
ibuted switch technology can improve the system reliability of frequency signal
and time-code signal over 40 percent. The technology can provide
reference for the reliability design of time unification system. |
| Key words: time unification system distributed switch reliability model failure rate |
