Abstract
Method and apparatus are disclosed for accommodating diverse signalling methods and protocols within a single, unified Radio Data Communications system without interference. In this way, improvements and new products may be integrated within a pre-established communications system without the need of discarding older equipment. Further, separate operating systems may be effectively merged without permanently modifying the merged system to one or another of the previous systems' signalling formats.
