6. TIME MONITORING
SVR-DS monitors the clocks of OIS-DS's, SVR-DS's, and PCS-DS's connected to the Ethernet
Control LAN of the TOSDIC-CIE DS system in a certain period (more than one munute). If the
allowable time difference (within five seconds) is exceeded, clocks are synchronized to the
system clock of own SVR-DS. If multiple SVR-DS's are connected to the TOSDIC-CIE DS
system, one of them is used for this purpose.
