Abstract
Global seismic network is one of the powerful means for research of earth interior's dynamics. IFREE install and operate broadband seismic network in western pacific region. For the purpose of recording high quality data, station should be operated stably without any suspensions. IFREE upgraded the recording system and installed IP communication line for latest five years. Therefore we constructed real time data archive and station's status monitoring systems. The rate of operation is much higher due to upgrade to telemeter station than off line recording period. It is realized that full length seismic data set is archived with minimum interruption.
