What is hwEntFxoPortAcImpedance?

Selects the AC line impedance profile of the FXO port from a list matched to specific national telephony standards (e.g. 0 = 600 ohm, 4 = 370+(620||310nF), 15 = Global impedance), defaulting to 0 (600 ohm). An admin sets this to match the impedance of the PSTN line or PBX trunk the port is wired into, for correct signal transfer and minimal echo.
