1 / 17 page  STLC5444 QUAD FEEDER POWER SUPPLY SUPPLIES POWER FOR UP TO FOUR DIGI- TAL TELEPHONE LINES CONFORMS TO THE CCITT RECOMMEN- DATIONS FOR POWER FEED AT THE S OR T REFERENCE POINTS SUPPORTS POINT-TO-POINT AND POINT TO MULTIPOINT CONFIGURATIONS EACH OF THE FOUR LINES IS INDIVIDU- ALLY CONTROLLED HIGH-VOLTAGE BCD TECHNOLOGY SUP- PORTING UP TO -130V AUTOMATIC THERMAL SHUTDOWN STATUS CONDITION DETECTION (BY MI- CROPROCESSOR) FOR EACH LINE: – Low output voltage – Openloop – Current overload – Thermal overload – Normal line condition PROGRAMMABLE CURRENT LIMITING OUTPUT CURRENT UP TO 120mA DESCRIPTION The ISDN Quad Feeder Power Supply (IQFPS) provides a power source for up to four line inter- faces. The power source to the device is a local battery or a centralized regulated power supply. It can operate in point-to-point and point-to-mul- tipoint configurations as far as S interface is con- cerned. By the device microprocessor interface, each powered line is individually controlled and moni- tored. Therefore, overloads and faults are easy to detect and localize even in a large system. The status conditions detected by the device on each line that may be read by the microprocessor are : low output voltage openloop current overload thermal overload normal line conditions A hardware current limiting programmable feature is available.
