Changing the channel map over to the analogue on an all digital DCT would cause the analogue channels to not come through & would not bring through the security camera channel. To do that you would definitely need a DCT with a built in analogue tuner (older models that magnet mentioned).

John: Older DCTs have an analogue tuner that can bring in analogue channels as well as the digital version of those channels if flipped to the all digital map. Newer terminals only can get the all digital map and analogue channels only come through in digital format.

The TV Listings channel is typically only available when you have an analogue tuner (as the DCT has a built in listings you wouldn't need this channel). I believe all other channels are duplicated on the digital only map with the exception of the security camera channel as this is typically an in house camera that almost always only outputs in analogue format and not digital.
@johnnucleo: as for getting onto the analogue version of the map in an all digital area they may start you out on this but there are processes run every so often to move customers off this map over to the digital version in all digital areas.
