Title:
RADIO TELEPHONY EQUIPMENT
Document Type and Number:
Japanese Patent JPH05284080
Kind Code:
A
Abstract:

PURPOSE: To make the radio telephony equipment compact by reducing the number of terminals at an external connector in the equipment provided with a test mode.

CONSTITUTION: While a phone mode is set, a phone mode terminal 110c of a gate array 110 is turned to 'H' and while that mode is not set, the terminal is turned to 'L.' On the other hand, when a terminal 101a used for both of a test mode and a phone alert and a ground terminal 101b are short-circuited at an external connector 101, the test mode terminal 110a of the gate array 110 is turned to 'L.' Therefore, the test mode is started when the state of the phone mode terminal 110c is 'L' at that time.
