The ownership parameter can be set to:
Clear: No reservation shall be made.
Local: The reservation can be used by this base station for FATDMA
and unscheduled transmissions. Reservations for the base station’s
own messages (4, 17, 20, 22, 23 and 24) must be made as Local
reservations.
Remote: The reservation is made on behalf of another FATDMA
transmitter and is not used by the local base station. Use this when
you want to reserve slots for an AtoN unit or another base station.
Number of frames ahead for which other VDL users shall reserve the slots.
Thus, a value of 7 means that a mobile transponder can use the reserved
slots after 7 frames have passed since it lost contact with the base station.
