I just got done troubleshooting a 650 link for our landlord we are coloed with on a couple towers. I had not looked at the ptp interface since the 500.
This thing is freaking beautiful, and I never compliment anybody, especially on a web gui. Sooooo much information, so easy to find. one question though, They have atpc set to -35 on these, does that basically turn atpc off, or could it cause a problem? Im pretty sure they have a loose antenna or damaged feedhorn/patch cables (this was a lighnting replacement of a ptp500, reusing the cables/feedhorn) The system statistics showed a variation of received power ranging from -47 to -78 with a peak of -110 , -78ish being current. Transmit powers show a variation of -15dBm up to 21 dBm (I did not notice the negative value at first). This would account for the range of Received power except When the Status screenshots were taken, the transmit power on both units was at 21 dBm with a 77/78 receive power on each side. If the output power is accurate, the receive power on the remote end would be at the peak, not the mean. -- All parts should go together without forcing. You must remember that the parts you are reassembling were disassembled by you. Therefore, if you can't get them together again, there must be a reason. By all means, do not use a hammer. -- IBM maintenance manual, 1925
