Rx Nac Operation: Receiver Monitor; Rx Nac Operation: Community Repeater; Rx Nac Operation: Multi Nac - Futurecom PDR8000 Manual

6.6.2.1.2 R NAC O
X
If the active PDR8000 channel is programmed for Rx NAC operation of Receiver Monitor then
the PDR8000 receives all incoming transmissions (regardless of NAC embedded in the received
packet). If this PDR8000 is configured as a Repeater, it retransmits using the Tx NAC found in
the first enabled row of the Multi-NAC table. Any infrastructure-originated (e.g., console) calls
are also sent with Tx NAC from the first enabled row of the Multi-NAC table. Console-originated
transmissions initiated via DFSI may either provide the specific Tx NAC to be used as part of
the transmission information, or the console may defer to the PDR8000's configured Tx NAC by
specifying a Tx NAC of $F7E.
It may be desired that console-originated transmissions utilize the previously received NAC
code, to allow a dispatcher to reply to the previous call. This functionality is provided if the
channel is configured to Tx Last Rcvd NAC. For that configuration, for a configurable duration
of time since the last received call, the PDR8000 sends outbound wireline-originated
transmissions encoded with the NAC of the last received message. (A DFSI-connected console
may utilize this functionality by specifying Tx NAC of $F7E, or may override this behavior by
providing a specific Tx NAC as part of the transmission information.)
6.6.2.1.3 R NAC O
X
If the active PDR8000 channel is programmed for Rx NAC operation of Community Repeater
then the PDR8000 receives all incoming transmissions (regardless of NAC embedded in the
received packet). If this PDR8000 is configured as a Repeater, it retransmits all messages with
the same NAC as that received. When the PDR8000 sends a transmission originating from the
wireline interface, it is sent with Tx NAC from the first enabled row of the Multi-NAC
table. Console-originated transmissions initiated via DFSI may either provide the specific Tx
NAC to be used as part of the transmission information, or the console may defer to the
PDR8000's configured Tx NAC by specifying a Tx NAC of $F7E.
It may be desired that console-originated transmissions utilize the previously received NAC
code, to allow a dispatcher to reply to the previous call. This functionality is provided if the
channel is configured to Tx Last Rcvd NAC. For that configuration, for a configurable duration
of time since the last received call, the PDR8000 sends outbound wireline-originated
transmissions encoded with the NAC of the last received message. (A DFSI-connected console
may utilize this functionality by specifying Tx NAC of $F7E, or may override this behavior by
providing a specific Tx NAC as part of the transmission information.)
6.6.2.1.4 R NAC O

If the active PDR8000 channel is programmed for Rx NAC operation of Multi NAC, then the
PDR8000 utilizes the full Multi-NAC table to allow filtering and translation. The PDR8000 only
processes messages received over the air with Rx NAC that is equal to any of the RxNAC
entries found in any enabled row of the Multi-NAC table. (Packets received with other NAC
values are ignored.)
When the PDR8000 repeats an over-the-air transmission it uses Tx NAC found in the same row
as the corresponding Rx NAC of the Multi-NAC table. When the PDR8000 sends a
transmission originating from the wireline interface, it is sent with Tx NAC from the first enabled
