COMMUNICATION SYSTEM AND METHOD FOR ADDRESSING MULTIPLE CAPACITY WIRELESS TRUNK

摘要

PROBLEM TO BE SOLVED: To provide a system and method for addressing multiple capacity wireless trunks. SOLUTION: This communication system includes a central telephone switch such as a private branch exchange or key system, connected through one or more trunk lines to a wireless access communication unit 106. The wireless access communication unit preferably includes an individual subscriber interface 104 for each line from the central telephone switch. The wireless access communication unit 106 collects data from each of the subscriber interfaces, formats the data into a format compatible with an over-the-air protocol, and transmits the information over one or more wireless channels to a cellular base station. The wireless access communication unit thereby connects calls received from the central telephone switch's trunk lines over a wireless trunk to a network. COPYRIGHT: (C)2009,JPO&INPIT
