966 NOXX10 KWBC 302034 DATA MGT 09-02.22 UPLINKING OF THE SATELLITE BROADCAST NEWTWORK /SBN/ DATA STREAM WAS TRANSFERRED TO THE BACK UP MASTER GROUND STATION /BMGS/ LAST WEEK. SINCE THE BMGS USES THE FASTER LINUX-BASED COMMUNICATION PROCESSORS EVERYONE HAS NOTICED AN INCREASED THROUGHPUT ON THE NWSTG AND GOES CHANNELS UNFORTUNATELY THIS INCREASED THROUGHPUT HAS CAUSED SOME PROBLEMS AT SOME NON-AWIPS SITES. THE NCF WILL MAKE SOME CHANGES AT THE BMGS TO THROTTLE BACK ON THE SBN DATA STREAM TO INSURE NON-AWIPS SITES DO NOT LOSE PRODUCTS. THESE CHANGES WILL RETURN THE SBN THROUGHPUT TO ABOUT THE SAME LEVELS AS EXPERIENCED WHEN OPERATING FROM THE FT MEADE MGS. . THE CHANGES WILL BE IMPLEMENTED AT APPROXIMATELY 12 30Z 1 OCT 02. THERE MAY BE A VERY SLIGHT INTERRUPTION TO THE DATA FLOW ON THE NWSTG CHANNEL BUT THE AUTOMATIC TRANSMISSION CAPABILITY WILL ENSURE ANY MISSED PRODUCTS ARE RETRANSMITTED. THE CHANGES ON THE GOES CHANNEL WILL TAKE PLACE BETWEEN VOLUME SCANS AND NO DATA INTERRUPTION IS EXPECTED. THE THROTTLED DATA STREAM WILL REMAIN IN PLACE FOR APPROXIMATELY 45 DAYS TO ALLOW THE NON-AWIPS SITES TO UPGRADE THEIR EQUIPMENT. WEATHER PERMITTING THE PRIMARY MGS AT FT MEADE WILL BE UPGRADED TO THE FASTER LINUX-BASED COMMUNICATIONS PROCESSORS ON OCTOBER 1 02. THESE PROCESSORS WILL ALSO BE THROTTLED BACK TO ACCOMMODATE THE NON-AWIPS SITES FOR THE REMAINDER OF THE 45-DAY PERIOD. ---------- End Forwarded Message ----------
