16 MULTI RF DECK/ MULTI CONTROL HEAD
16.18 Relaying the Received Signal (Mobile Relay Station)
Operation example 2
This is the example of the operation if Mobile Relay Station is used via a repeater with the UHF transceiver as the
transmitting unit and the VHF transceiver as the receiving unit in a P25 Conventional system.
The channel configurations of RF Deck 1 and RF Deck 2 are as follows:
RF Deck Unit ID
RF Deck 1 1
RF Deck 2 2
Source Unit ID = B
Talkgroup ID = B (Unit ID = B)
TX Freq = 470.5 MHz (Repeater)
NAC Enc = 29E (Repeater)
Subscriber Unit A
(UHF)
Unit ID = A
Talkgroup ID = B
RX Frequency = 470.5 MHz
TX Frequency = 465.5 MHz
NAC Dec = 29E
NAC Enc = 29A
Note
Mobile Relay Station does not function if the received signaling does not match the signaling preconfigured for the
0
receiving RF Deck.
QT/DQT is decoded regardless of the status of Off-hook Decode and microphone hook.
0
Time-out Timer executes according to the configuration.
