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.
