Newer scanner model from Uniden (the SC230, BC246T, BR330T, BCD396T, BCT15 and the BCD996T) incorporate a new memory technology known as Dynamic Memory Architecture, or DMA.
DMA allows for more efficient and flexible use of scanner memory by not imposing fixed sizes for banks or scanlists. This type of memory architecture uses memory spaces more efficiently and eliminates unused memory channels or spaces.
Instead of being organized into separate banks and channels, the scanner’s memory is contained in a pool. You simply use as much memory as you need in the pool to store as many frequencies, talk group ID’s, and alpha tags as you need.
The radio can be configured to have multiple “Systems” containing multiple “Groups”. A Group can contain conventional frequencies or Talkgroup IDs in a trunked system. The size of a System and the Groups within it are only limited by the amount of available memory in the radio.
DMA Memory requires that frequencies be programmed in a "System > Sub-System" hierarchy. Conventional Systems contain only Groups of frequencies. Trunked systems contain one Group of frequencies and multiple Groups of Talkgroup IDs arranged in any logical order you want.
A site is group of frequencies, or channels, used by a particular geographic location in a Trunk system. A Trunk system can have many sites, each containing a set of frequencies associated with that geographic site location.
