> It seems to also be known as a "TImeCesium". I've been looking around on the internet, and I don't find a lot of information on these other than the user document on N4IQT's site. Is anyone using one of these, and do you have the software for it?
I bet it has the same cesium platform as my Telecom Solutions, and then
the FTS-4065 software on the RS-232 port should be exactly what you want.
PRS = Primary Reference Source - the ANSI SONET term which is also
associated with Stratum 1. The two DS1 outputs is means to feed the
PDH/SONET network in the 1,544 Mb/s hierarchy.
I had a tool for pulling that datastream out of it, but it was relative
easy to write a tool from the FTS manual as I recall it, but I never got
around to do it. You do want to record the output of the RS-232 to a
log, so you can monitor the state of it and see how it behavves.
