DESCRIPTION
The ISDN Quad Feeder Power Supply (IQFPS) provides a power source for up to four line interfaces. 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-multipoint configurations as far as S interface is concerned. By the device microprocessor interface, each powered line is individually controlled and monitored.
■ SUPPLIES POWER FOR UP TO FOUR DIGITAL TELEPHONE LINES
■ CONFORMS TO THE CCITT RECOMMENDATIONS 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 INDIVIDUALLY CONTROLLED
■ HIGH-VOLTAGE BCD TECHNOLOGY SUPPORTING UP TO -130V
■ AUTOMATIC THERMAL SHUTDOWN
■ STATUS CONDITION DETECTION (BY MICROPROCESSOR) FOR EACH LINE:
– Low output voltage
– Openloop
– Current overload
– Thermal overload
– Normal line condition
■ PROGRAMMABLE CURRENT LIMITING
■ OUTPUT CURRENT UP TO 120mA
