Connect the prototype ground to the EVB ground.
Lift prototype C1 and C2 and EVB C1 and C2 so the Si3008 is disconnected from the Si24xx on both modems.
Connect EVB C1 and C2 to the Si3008 pad of prototype system C1 and C2.
Connect the phone line to the RJ11 jack on the prototype system.
Use PC and HyperTerm and attempt to establish a modem connection.
Connect prototype system ground to EVB ground
Remove modem module from EVB
Disconnect host outputs from prototype modem
Connect EVB RS232 transceivers to prototype modem
Use PC with HyperTerminal to test prototype modem
