WIRELESS ACCESS MODULE INTERSACE APPARATUS IN SMALL IP PRIVATE SWITCHING SYSTEM AND WIRELESS ACCESS INTERSACE METHOD USING THE SAME

摘要

PURPOSE: A wireless access module interface apparatus in small IP private switching system and wireless access interface method using the same are provided to enable a user to freely perform communication where a PSTN is not installed. CONSTITUTION: A local bus matching unit(105) performs as a communication access part between a main controller and a controller. A decoder clock generating unit(106) creates a clock signal and a control signal about an echo signal canceller, a CODEC part, and a serial communication part(107). The serial communication part offer communication path between the controller and a wireless connection module. The serial communication part exchanges the operation state of a communication data and the wireless connection module with the controller.
