That brings up another interesting point that I failed to mention in my original posting. I am a little confused as to the definition of full duplex. When I think full duplex, I think that of like a telephone conversation where the caller and receiver can both talk at the same time. How exactly does this work in App_rpt? I only have one radio to work with with one simplex frequency, is this not intended for this type of setup?

That sounds like a more economical solution. Do you plan on having this anytime soon?
One of the biggest things that attracted me to this project was openness. I think echolink and IRLP are excellent systems, but too closed and proprietary in nature which prohibits experimentation. I hope this project goes far!

You will need the following in addition to what you have already listed:
1. A digium TDM400 with one FXS daughterboard. Digium part number TDM10B. This
is going to cost around $140.00. There is a Chinese knockoff of the TDM400p
part number A400P10 for $93.00 which we haven't tested available from
openvox: http://www.openvox.com.cn/products_detail.php?genre_id=9&id=27.
2. One ARIB board. This board can be built for around $60-$70. Board blanks
are available from us for $10 each plus shipping.
3. A modular to modular to modular telephone cable.
We would like to suggest you plan to build a full-duplex system as this will
provide much more flexibility than a simplex node.
BTW: We are working on a less expensive solution which requires 2 of
inexpensive X100p FXO cards (around $10-$20) plus a modified ARIB, but it
isn't ready yet as it requires either changes to the ARIB, or an addtional
external board.
