[BC] "live" feeds

[Broadcast List USER]

All good ideas, but it might be easier to just have them install a  
T-1.  Most campus IT/phone departments speak digital today much  
better than analog.  Also, the T-1 or fractional won't go away as  
easily.  Funny thing about dry pairs...

IF you use a dry pair, put tone on it when it isn't in use.  Today  
you could put a digital play back device on the line.  I have used  
very inexpensive MP3 players for this application.  Just record a  
file of what the line is used for, and maybe even a few test tones so  
you know it is still good, say 50 Hz, 100 Hz, 200, 400, 1kHz, 2.5k Hz  
and 5 kHz.  That way you can hang a meter on the line from time to  
time and see how is is doing.
