Title: Remote Down at Particular time
Post by smlt_vsat on Feb 22^nd, 2009 at 7:29am

Dear

Last 3-4 days i noticed that one of our terminal going down in between 8 AM - 9 AM . all these days it starrted almost on the same time. monitoring this i found out that Dn Stream was gradually falling down and later outage. but late in 9 AM it came automatically back to the network. During the total outgae of this remote , i send a CW and couldnt see anything transmit. so i assume that RX is compltely lost. This is situated in an Market . what could be the possible reason

regards

I think we are a little early for the spring equinox (solar conjunction) so it is doubtful that is the cause.

1. Do you have other remotes in that network? �What are they reporting? � Are they experiencing and downstream falls around the same time?
2. Is this a C-Band link? �
3. Is the downstream SNR slope gradual or abrupt when it falls off? �If gradual it is possibly weather related.
