Zusammenfassung:A SELF-DIAGNOSTIC SYSTEM FOR A CHECKING ALL FUNCTIONS OF A CELLULAR-TRANSCEIVER SYSTEM HAVING A CELLULAR-INTERFACE UNIT, WHICH INTERFACE UNIT COUPLES A STANDARD TELEPHONE SET TO A CELLULAR TRANSCEIVER, WHICH INTERFACE UNIT CONVERTS THE DTMF OR PULSE-TYPE OF DIALING SIGNALS INTO DIGITAL FORMAT FOR TRANSMISSION TO THE CELLULAR TRANSCEIVER, WHEREBY THE DIALED NUMBER MADE ON THE LAND-TYPE OF TELEPHONE MAY BE USED TO CALL A NUMBER OVER THE CELLULAR SYSTEM. THE PRESENT INVENTION NOT ONLY MONITORS AND CHECKS THE PROPER FUNCTIONING OF THE TRANSCEIVER AND ASSOCIATED POWER SUPPLY, AND THE LIKE, BUT WILL ALSO MONITOR AND CHECK THE INTERFACE UNIT. (FIG. 10)
