Rx/TA DPL Invert

(Conventional MPL Configuration, MPL List)

Selects for Digital Private Line (DPL) signals to be inverted when they are received by the radio while operating on the current MPL (Multiple Private Line) List - (record / row). Inverted coding allows for more traffic / usage on frequencies.

	When the Direct Frequency field is enabled, the MPL Direct / Talkaround parameters can then be modified on a per MPL List basis. Once modified, the radio may then be transmitting and receiving on a different carrier frequency and or frequency parameters while operating in Direct / Talkaround mode.
	When the Direct Frequency field is disabled, the settings for MPL Rx parameter fields are also used for Direct Talkaround functionality. Therefore when in Direct / Talkaround mode, the radio is transmitting and receiving on the same carrier frequency and frequency parameters.
	Direct / Talkaround must be enabled on a frequency options profile in order to be available to the radio-user for a radio channel. Direct/Talkaround mode is selected by the radio-user with the Direct / Talkaround button-press, the Talkaround / Direct switch-selection, or the Direct / Talkaround menu selection.

	DPL Invert must be set on both receiving and transmitting radios for communication to occur.
	The MPL menu can only be accessed by the radio-user when the radio is operating on a Conventional communications channel that has its Rx Voice / Signal Type field set to "Non-ASTRO", and has its User Selectable PL [MPL] field enabled.
	Either the Multiple Private Line button-press or the Multiple Private Line menu-selection must be CPS-defined thus allowing the radio-user to select the desired PL settings / list.

When Rx / TA Squelch Type is set to "DPL", and

when the radio is model / option capable.
