[App_rpt-users] Interfacing Motorola Quantar to quadpci radio card

[Bryan Fields]

I don't know if anyone has done this before (I'm sure it's been done), but
I've not seen a document on it.

I use the quad port radio cards with app_rpt/asterisk as allstar nodes and
needed to interface a quantar station with them.  I've built the following up
to allow some one to build it directly into a box with a RJ-45 jack, so you
only need a patch cable to connect to the quad port card.  Some pictures of my
second prototype are up here
<http://gallery.keekles.org/v/Radio_stuff/Quantar_PCIradio/>.

Additionally I've setup the wildcard tables on the quantar to have a seperate
COS and PL decode output to the quad port card. 
There is a final input for alarm status on the station, but Ive not figured
out how to do anything useful with it in app_rpt just yet.

This is my system.conf for dahdi in this configuration:

e&m=1    # This needs to match the number of channels used in rpt.conf
loadzone = us
defaultzone=us
exttone=y
invertcor=n
channels=1     #apply it to port 1

I bought a 10' male to male rj-21 cable off ebay, and cut it in half.  It
works perfect on the back of quantar.  My document shows the standard color
codes used by these cables and how the pairs are laid out, much more logically
than the service manual.

If anyone has any feedback or ideas send them my way.

Thanks and 73's
