[BC] Designing a four station RF STL system

Harris Aurora did two T-1's in a single 5.8Ghz system.  There were others 
too.  But that is unlicensed and depending on the location, prone to IX 
outages.  You need a really unique path for the system to not suffer IX 
related outages.

With two T-1's you can run slightly compressed audio through them for four 
stations.  OTOH, the Intraplex system has the PTR255 cards which will do 
Layer 2 or 3 at 384 Kbps per joined stereo pair.  You can put 4 stereo 
pairs on one T-1.  And they're bidirectonal...which means they send audio 
in both directions on one set of cards.  Great for back-hauling.  1/2 the 
price of a set of PT/PR350 cards.

Harris really hated to sell me those cards as we both knew that they were 
THE best deal for bandwidth utilization versus cost in the whole product 
line. Whether they sell them at all right now is something entirely 
different.  But rest assured, they sound good on both AM and FM as long as 
what's feeding them is already not bit rated reduced.  I'm using them all 
over the place....and Harris cringes every time I call wanting more of them.
