Migration path

1. Introduce a digital system into a current network step by step

2. Operate in analogue and digital modes in the different frequencies

3. Within the digital group communicate in digital mode

4. Communicate between a digital group and the analogue group in analogue mode

Original Network – analogue only operation

Phase 1: Introduce a digital system into Group C

•Partially introduce a digital system into an existing

analogue network

•Replace the transceivers from analogue to digital in

Group C

•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 analogue signal

when received from Groups A and B

Phase 2: Introduce a digital system into Group B

•Expand the digital system into a mixed operating

network

•Replace the transceivers from analogue to digital in

Group B

•Set the Talk Back ON in the scan list setting for the

transceivers in Group B to transmit an analogue signal

when received from Group A

Phase 3 Introduce a digital system into the Group A

•Convert to a full digital network from a mixed operating

network

•Replace the transceivers from analogue to digital in

Group A

•Cancel analogue operation
