Features, Applications


by a pin strap. Each line can be individually powered and monitored: therefore overload and faults can easily be detected and localized even in a large system. The status conditions detected by the device are: Current Overload, Thermal Overload, Open Loop. If activated (by means of a dedicated pin strap), a self generated power on sequence avoids the thermal over stress when a simultaneous power on has been requested for more than one channel. The current limiting value can globally be programmed for the four channels by means of an external resistor. The device has two integrated relay drivers per line to drive the test relays of the ISDN system.

DESCRIPTION The QUAD LINE FEED CONTROLLER provides a power source for up to four U line interfaces. The power source to the device is a local battery or a centralized regulated power supply. Each powered line is individually controlled and monitored by the device interface. A MPI or a simple parallel interface can be selected
