SUBJECT: AWIPS SBN STATUS UPDATE
.
ON SUNDAY DECEMBER 5TH AT APPROXIMATELY 2100Z, THE AWIPS
NCF MOVED ALL AWIPS NWS SITES TO A TEMPORARY FREQUENCY
DUE TO SBN INTERFERENCE PROBLEMS THAT WERE FOUND ON THE
ORIGINAL AWIPS SBN FREQUENCY.
.
DURING THE PAST 24 HOURS, THE NCF HAS WORKED WITH THE
SATELLITE PROVIDER, GLOBECOM, TO ENSURE ALL INTERFERENCE
PROBLEMS EXPERIENCED THROUGHOUT THE WEEKEND HAVE BEEN CORRECTED. TODAY
BETWEEN 1930Z AND 2000Z, GLOBECOMM WILL
PERFORM INTRUSIVE TESTING ON THE ORIGINAL AWIPS SBN SIGNAL.
ALL AWIPS OFFICES ARE STILL CURRENTLY USING THE TEMPORARY
AWIPS SBN FREQUENCY AND WILL NOT BE IMPACTED BY THE INTRUSIVE TESTING THAT IS
TAKING PLACE. EXTERNAL NOAAPORT USERS THAT
ARE CURRENTLY USING THE ORIGINAL AWIPS SBN FREQUENCY MAY
EXPERIENCE BRIEF DATA OUTAGES WHILE TESTING IS TAKING PLACE.
.
TOMORROW, DECEMBER 8TH BETWEEN 1400Z AND 1500Z, THE NCF WILL
RE-POINT ALL NWS OFFICES BACK TO THE ORIGINAL AWIPS SBN
FREQUENCY. THE SWITCH BACK TO THE ORIGINAL AWIPS SBN
FREQUENCY WILL BE DONE REMOTELY BY THE NCF AND SITES
SHOULD NOT SEE ANY DOWNTIME AS A RESULT OF THE SWITCH
BACK TO THE ORIGINAL FREQUENCY. ONCE ALL SITES HAVE BEEN
RE-POINTED BACK TO THE ORGINAL AWIPS SBN FREQUENCY,
ANOTHER ADMIN MESSAGE WILL BE SENT.
.
ON DECEMBER 8TH AT 1600Z, THE TEMPORARY AWIPS SBN FREQUENCY THAT
WAS ESTABLISHED WILL BE TERMINATED. ANY EXTERNAL NOAAPORT
USERS POINTED TO THE TEMPORARY AWIPS SBN FREQUENCY WILL
NEED TO SWITCH BACK TO THE ORIGINAL AWIPS FREQUCNCY BEFORE
1600Z ON DECEMBER 8TH.
.
THANK YOU FOR YOUR CONTINUED PATIENCE WHILE THESE ISSUES
ARE BEING RESOLVED.
