	Our local TV people are in the process of setting up a microwave link
here on campus.  They are looking at 23 Ghz systems.  I would like to be able
to add IP traffic to their setup.

	As I understand things, the 23 Ghz systems use a 10 Mhz bandwidth.
DC to 4.5 Mhz is used for the video signal.  They usually put the audio
signal at 6.2 Mhz with a 75 Khz deviation.  They also use 5.8 Mhz (not so
good of an audio channel due to synch buzz) and have second audio channels
at 6.8 and 7.5 Mhz.

	They said we could use one of the second audio channels to run
data on -- using modems at 56kbps.  Personally I would like to use T1 or T2
which should fit in the extra bandwidth.  Unfortunatly the manufacture (Macom)
doesn't offer any T1 capablility -- as far as we know.

	It seems that where we want to have data they want to have video and
visaversa.  It would be real nice if we could find a microwave system that
did video, audio, and at least one T1.

	If you have any experience with running data over microwave links
with video I would like to hear from you.  I would be interested in any
horror stories, actual setups that you are using, manufactures of equipment,
etc...

	Thanks,
		-Jim
