The "grant demand" TDUs set a flag in the control bit of the P25 network header (bit $80) to flag that the TDU is meant to trigger a channel grant on a end-point. +For DMR, "grant demands", are carryed along side the VOICE_LC_HEADER or DATA_HEADER packets with the control bytes set. Like, P25, the "grant demand" set a flag in the control bit of the DMR network header (bit $80) to flag that the packet is meant to trigger a channel grant on a end-point. + Because these grants are considered "network sourced" end-points should issue a grant locally and not repeat that grant to the network. + +(See Section 3.3.1 for P25, and Section 3.2 for DMR)
