Has anyone written a tool to turn the contents of S71, S73, and S76 into plot(1) input or perhaps PostScript?

The Telebit Demonstation System (TDS), which is based on a water-down version of HyperACCESS for DOS, has the capability of charting the S70/S71/S72/S73 and S76 registers. The plotted output first gives you the noise level plotting of S76 (ie usable bandwith) then superimposes the Transmit Bits Per Channel (S71) OR the Receive Bits Per Channel (S73). The axis of the plot are: | | Bits | | Noise level Per | | (dbm) Channel l | (2,4,6) | | |_______________________________| Bandwith (0-4000Hz) Unfortunately, this TDS software is only for use with the a PC-DOS HyperACCESS system running the full-blown host end of the Telebit Demon- stration System (which is normally not made available to the end users, only to us Telebit distributors...:-(. The TDS software is available from Telebit or its distributors for < $50. Once you buy it, you dial the number to the Telebit Demonstation System Host (in Sunnyvale, CA - 408) and it automatically logs you in and presents a demonstration menu which will include the plotting program. TDS is in binary form ONLY! I don't know of where to get the code to write a plotting program for any other type of O/S, although it should be fairly simple to do using text files and plotting utilities, commonly available in UNIX. Please feel free to e-mail me if you would like this DOS software and the TDS HOST phone number, if it is still in operation. I'll be glad to help you with this. =============================================================================== Cerafin E.

>Has anyone written a tool to turn the contents of S71, S73, and S76 >into plot(1) input or perhaps PostScript? I have an extremely crude perl script that converts the S71 and S73 data in spectrum plots. Up to four plots can be overlayed; I used this to show both the transmit and receive numbers for two different phone lines. The output is piped into an ascii-input-to-plot-output filter. The whole shebang was used to document for our telecom department that MCI lines were of much poorer quality than our AT&T lines. (Didn't help. They went for the short-term false economy. I can't even guess how much switching to MCI has cost us in reduced modem throughput.) Send e-mail if you want a copy. No warranties; this is hack-and-slash perl we are taking about here, and it's not very pretty. <csg>
