Selector 8: PABX loop current control (Not used.)
This selector determines whether the PABX loop current control will be enabled or disabled.
Setting this selector to "1" enables the loop current control that automatically switches the internal
resistance inserted in series with the communications line on and off depending upon the loop
current amount. Setting this selector to "0" disables the loop current control and keeps the internal
resistance on.
For some PABXs that are not compatible with the machine in voltage rating, set this selector to "0."
The setting made by this selector takes effect only when the user selects the PABX. If no PABX is
selected, the PABX loop current control will be enabled independent of this setting.
