Analog To Digital Migration Path - Icom IC-FR5000 Series Sales Handbook

Migration Migration path Migration Migration path path path
1. Introduce a digital system into a current network step by step
2. Operate in analog and digital modes in the different frequencies
3. Within the digital group communicate in digital mode
4. Communicate between a digital group and the analog group in analog mode

Phase 1: Introduce a digital system into Phase 1: Introduce a digital system into Group Phase 1: Introduce a digital system into Phase 1: Introduce a digital system into
• Partially introduce a digital system into an existing
analog network
• Replace the transceivers from analog to digital in
Group C
• Add a digital repeater • Add a digital repeater
• Allocate new frequencies to the digital network
• Set the Talk Back ON in the scan list setting for the
transceivers in Group C to transmit an analog signal
when received from Groups A and B
