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.
