NOVELTY - The system (200) has a circuit pathway coupling a network interface unit (NIU) (204) to a direct current (DC) bus (208) and including a relay (222). The relay senses a voltage condition across an energizing coil (228) within a conductive pathway (220) and opens the pathway upon the energizing coil becoming energized in response to a low voltage disconnect (LVD) (218) decoupling a base-transceiver-system electronics from the bus within another circuit pathway, where electrical current flow to the NIU from the bus is prevented when the relay opens the former pathway.    USE - System for providing failsafe protection for telecommunications equipment e.g. base transceiver station (BTS) and NIU, located at a distributed telecommunications site, to provide mobile communications between cellular or mobile communications device e.g. mobile phone and personal digital assistant.    ADVANTAGE - The system minimizes damage on the equipment located at the telecommunications site during a period of electrical power drain. The relay senses low voltage condition through the energizing coil and acts to open a switch on conductive pathway to decouple the NIU from the DC bus, so that the system ensures that the NIU ceases operation when power is lost to a base transceiver system.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (1) a method for providing failsafe protection for equipment located at a distributed telecommunications site    (2) a system for inhibiting drain on a DC electrical power supplying device connected with telecommunications electronics at a distributed site.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic block diagram of a failsafe protection system for a distributed telecommunications site in which associated telecommunications equipment is coupled to a power supply.
