APPARATUS OF CONNECTING FOR PORTABLE PHONE IN CDMA MOBILE CALL SIMULATOR

摘要

PURPOSE: A portable terminal access device of a CDMA mobile call simulator(MCS) is provided to increase a commercial benefit by accessing a portable terminal to the CDMA MCS through an access device. CONSTITUTION: An RS 232C transceiver(11) is used in order to transmit and receive control orders with an operation device. An RS 232C transceiver(12) is operated between an operation device(3) and a portable terminal(1), and is enabled or disabled at a control card(5). An interrupt logic circuit(10) processes an interrupt generated in performing read/writing at a dual port SRAM(13) for data transmission between the control card(5) and a tone transmission/receipt card(6). The dual port SRAM(13) exchanges data about an order transmission and a response between the control card(5) and the tone transmission/receipt card(6).
