ABSTRACT:
A centralized telephone interconnect system for an RF multisite system. Multiple publicly trunked radio sites are networked together through a multisite switch. The centralized telephone interconnect system couples a series of land telephone lines to the multisite switch so that a mobile radio user anywhere in the multisite system is accessible to telephone communications. The telephone interconnect system supports individual calls, group calls and dispatcher console calls. The system includes a centralized interconnect controller that supervises the operation of the interconnect system and a telephone line switching network that connects telephone lines to the multisite switch. A centralized telephone interface module within the multisite switch connects to the centralized interconnect controller and switching network.
