Abstract
THE THIRD OR THREE, THIS VOLUME DESCRIBES THE PHYSICAL FEATURES AND FUNCTIONAL CAPABILITIES OF THE TERMINAL ELEMENTS THAT WERE MADE AVAILABLE TO SYSTEM USERS AT EACH OF THE 17 STATIONS IN THE 'PICTUREPHONE' NETWORK IMPLEMENTED IN THE PHOENIX/MARICOPA COUNTY, ARIZONA, CRIMINAL JUSTICE SYSTEM. THE 17 STATION SETS, LOCATED IN 7 CRIMINAL JUSTICE AGENCIES, COMPRISE VARIOUS COMBINATIONS OF 13 SPECIFIC TYPES OF EQUIPMENT. ALL STATIONS USE A STANDARD PUSHBUTTOM TELEPHONE COUPLED WITH A WESTERN ELECTRIC COMPANY DISPLAY UNIT, WHICH IS A SOLID STATE, BLACK AND WHITE VIDEO MONITOR AND CAMERA ON A 'LAZY SUSAN' BASE. THE VIDEO NETWORK CONSISTS OF FULL DUPLEX 4.5MHZ COAXIAL CABLE AND MICROWAVE RADIO CONNECTED THROUGH THE CENTRAL EXCHANGE OF THE LOCAL TELEPHONE COMPANY. STATIONS DIAL-UP EACH OTHER FOR FACE-TO-FACE CONVERSATIONS. A THREE-WAY CONFERENCE BRIDGE IS ALSO INCLUDED AS PART OF THE NETWORK. TEST FINDINGS INDICATE THAT THE GRAPHICS REPRODUCTION CAPABILITY IS MARGINALLY SATISFACTORY BUT THE DEGREE OF SATISFACTION VARIES WITH THE TYPE OF MATERIAL BEING DISPLAYED. FOR THE OTHER TWO VOLUMES IN THIS REPORT, SEE NCJ-38950 AND 51. (AUTHOR ABSTRACT)...ELW
