Randy answers that they are ALL on-air monitors at the Cox facility.

We were treated to a tour of the amazing new COX facility by Robert Lonn
and our own Randy Phillips. It is one of nine buildings that pipe fibre optics to Cox customers,
has the largest of Sprint PCS cell sites in the world, was built to meet
Bell standards of 99.999% reliability as well as supply UPS for all of this @ -48/+24 dc.
Commercial insertion is also accomplished in the video half of the facility.
If thats not enough we were treated to a demonstration of the video-on-demand feature.
Phone, cell, video and web service on cable is coming soon, very soon.

Marcy Rose of Trompeter set the fare then Dale Reed of Trompeter
fed us the skinny on piping uncompressed HDTV through coax. He brought us up to speed
by explaining the emerging SMPTE 292M spec requirements (1.485 Gbps is the data rate
but using Alternate Mark Inversion coding and the 3rd harmonic extends the uncompressed
maximum required frequency to 2.25 GHz). At this frequency RF effects like line loss
(attenuation) and impedance mismatch (return loss) become critical. A Trompeter BNC plug
tests 8dB better than "Brand X" and "Brand Y." As we all know digital doesnt Òfade awayÓ
like analog so the importance of a couple of dB on HDTV signal transmission was driven home.
Trompeter has a full line of broadcast coax connectors and patchjacks for
these elevated frequencies. To download info, go to www.trompeter.com and download the video catalogue.
