The FXO module provides the Foreign eXchange Office (FXO) interfaces. Up to six FXO

The standard FXO module supports outdoor and indoor (lightning protection) loop-
start signaling. The
FXO G module supports both loop- and ground-start signaling
(but only supports indoor protection).

To enable ground-start signaling, use the ini file parameter GroundKeyDetection
(refer to the device's User's Manual ).
