Hello everyone, Monday morning at 13Z (8 AM CST), the new DVB-S2 NOAAport broadcast begins (see below). NIU Weather is planning on remotely switching our Novra S-300 to the new broadcast after I'm half awake...probably around 14Z (9 AM) or so.I'll be using the new CMCS 1.8 Linux version that Novra gave me to do the switchover. If all goes well, I'd be up and running in 30 minutes or less. If I can't figure things out or mess things up, I've allotted an 8 hour maintenance window to clean up the mess.
WeatherX.admin.niu.edu all have IDD backup, and as such, no products should be lost. This will be done even if Monday is a severe weather day for us locally, unless it's bearing down on our area in an immediate threat Monday morning.
Thanks for your patience. ******************************************************************************* Gilbert Sebenste ******** (My opinions only!) ****** Staff Meteorologist, Northern Illinois University **** E-mail: sebenste@xxxxxxxxxxxxxxxxxxxxx *** web: http://weather.admin.niu.edu ** ******************************************************************************* NOUS72 KNCF 151421 ADMNCF ATTENTION: NOAAPORT/EXTERNAL CUSTOMERS WHAT - SBN/NOAAPORT EXPANSION AND HARDWARE UPGRADE DATE - APRIL 15, 2011 NOTICE - 006 -------------------------------------------- SBN ACTIVATION INFORMATION APRIL 18, 2011 ------------------------------------------- THE NEW -SBN NOAAPORT- SIGNAL HAS BEEN SCHEDULED FOR ACTIVATION THE MORNING OF 04/18/11 1300Z -------------------------------------------- -------------------------------------------- PLANNING DATES 1. PLANNED IMPLEMENTATION DATE - APRIL 18 2. DUAL ILLUMINATION DATES - APR 18 TO MAY 17 3. DECOMMISSION OLD DVB-S DOWNLINK - MAY 17 -------------------------------------------- AS EVERYONE IS AWARE, THE AWIPS PROGRAM IS IN THE PROCESS OF EXPANDING THE BANDWIDTH ON THE AWIPS SATELLITE BROADCAST NETWORK -SBN/NOAAPORT- FEED FROM ABOUT 10MBPS TO ABOUT 30MBPS. AS PART OF THIS EXPANSION, THE FEED WILL BE TRANSITIONING FROM A DVB-S TO A DVB-S2 STANDARD. ACCORDINGLY, ALL SITES WILL BE REQUIRED TO UPGRADE THEIR HARDWARE TO SUPPORT THE DVB-S2 STANDARD. ALL TECHNICAL SPECIFICATIONS AS WELL AS UPDATES ON THE PROJECT ARE AVAILABLE ON THE FOLLOWING WEB PAGE ------------------------------------------ WWW.NWS.NOAA.GOV/NOAAPORT/HTML/NOAAPORT.SHTML ------------------------------------------ A 30 DAY WINDOW OF DUAL ILLUMINATION IS PLANNED TO ALLOW NWS SITES AND NOAAPORT CUSTOMERS TIME TO COMPLETE THE TRANSITION. DURING THIS PERIOD, THE FULL -SBN/NOAAPORT- FEED WILL BE DISSEMINATED IN BOTH DVB-S AND DVB-S2. INTERNALLY, NWS PLANS TO USE BACKWARDLY-COMPATIBLE RECEIVE-SIDE HARDWARE TO ENABLE THE EQUIPMENT TRANSITION TO COMMENCE PRIOR TO THE DUAL ILLUMINATION PERIOD. AFTER MAY 17TH, THE ONLY SIGNAL DISSEMINATED OVER THE -SBN/NOAAPORT- WILL BE IN DVB-S2. THIS NEW AND INCREASED -SBN/NOAAPORT- BANDWIDTH WHICH WILL HELP TO ENABLE DISSEMINATION OF THE NEW PRODUCTS THAT ARE ON THE HORIZON FOR OUR CUSTOMERS WILL MAKE THIS A VERY EXCITING CHANGE FOR EVERYONE. IF YOU HAVE ANY QUESTIONS, WE ENCOURAGE YOU TO CONTACT US VIA EMAIL AT THE FOLLOWING ADDRESS NWS.NOAAPORT.SUPPORT@xxxxxxxx THANK YOU
