Abstract
Radio units responsive to a paging signal seize a trunk to connect wireless calls to telephone apparatus serviced by a private branch exchange. The radio units can each respond to a different set of mobile identification numbers, or can be configured in a master-slave arrangement or can employ subaddressing. Wireless trunking to a wireless private branch exchange can also be accomplished and a system with multiple hierarchical layers can also be formed.
