System Notes:
This is a DFA (Direct Frequency Access) system, and therefore CH ID (aka LCN) are not required. Uniden scanners that are capable of trunk tracking NEXEDGE systems will obtain the traffic channel information from the control channel.

You only need to program the control channel frequency into your Uniden scanner. The scanner will get the voice frequencies via the control channel when monitoring the site.

Direct Frequency Assignment (DFA) for efficient site/channel addition
Adopted Models：NXDN
With the flexibility inherent in NXDN Gen2, you can always keep the system up to date easily and quickly. When adding a new channel or site with older Gen1 models, it has been necessary to collect every single SU on the network for reprogramming. Then all the radios had to be sent back into the field.

What has changed all this is DFA – Direct Frequency Assignment – which ensures that as soon as new frequencies are added to the network, all equipment and subscriber units connected to the network are notified automatically. No radios have to be called in. Downtime is zero. Nothing could be more welcome for site managers and SMR operators who want to add channels or sites.
