Operation example 2This is the example of the operation if Mobile Relay Station is used via a repeater with the UHF transceiver as thetransmitting 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:Table 16-17 Mobile Relay ChannelRF Deck Unit ID Talkgroup ID ReceiveFrequencyTransmitFrequency NAC Decode NAC EncodeRF Deck 1 1 1 470.5 MHz 465.5 MHz 29E 29ARF Deck 2 2 2 144.5 MHz 145.5 MHz 29B 29CRF Deck 1UHF VHFKRK-15BControlHead 1KRK-15BRF Deck 2Subscriber Unit ASubscriber Unit BUnit ID = ATalkgroup ID = BRX Frequency = 470.5 MHzTX Frequency = 465.5 MHzNAC Dec = 29ENAC Enc = 29ARX Frequency = 465.5 MHzTX Frequency = 470.5 MHzNAC Dec = 29ANAC Enc = 29EUnit ID = BTalkgroup ID = BRX Frequency = 145.5 MHzTX Frequency = 144.5 MHzNAC Dec = 29CNAC Enc = 29BRepeaterSource Unit ID = BTalkgroup ID = B (Unit ID = B)TX Freq = 470.5 MHz (Repeater)NAC Enc = 29E (Repeater)Source Unit ID = BTalkgroup ID = B (Unit ID = B)TX Freq = 465.5 MHz (RF Deck 1)NAC Enc = 29A (RF Deck 1)Source Unit ID = ATalkgroup ID = B (Unit ID = A)TX Freq = 470.5 MHz (Repeater)NAC Enc = 29E (Repeater)Source Unit ID = ATalkgroup ID = B (Unit ID = A)TX Freq = 145.5 MHz (RF Deck 2)NAC Enc = 29C (RF Deck 2)Figure 16-82 Mobile Relay Station (Operation Example 2)Note0 Mobile Relay Station does not function if the received signaling does not match the signaling preconfigured for thereceiving RF Deck.0 QT/DQT is decoded regardless of the status of Off-hook Decode and microphone hook.0 Time-out Timer executes according to the configuration.16 MULTI RF DECK/ MULTI CONTROL HEAD16.18 Relaying the Received Signal (Mobile Relay Station)Common FUNC (K, F)/Ver 2.20 324CONTENTS INDEX
