FreePBX + Digium AEX2400E + 66 Block

I’m using Digium’s AEX2400E analog card with FreePBX 2.11.0.30 and have a question about what connections on the 66 block are actually being used. In FreePBX I have 4 FXOs on ports 33-36 and 8 FXS’ on ports 25-32. Does anyone know how this maps out on a 66 block?

It maps linearly, In your case the fxs will be on the first 8 pairs starting with blue-blue/white, the FXO’s on pairs 9-12 starting with red/brown
