| Hi Jee, Here is what it means; Status checking means supervision of circuit 108 in the V.24 interface and heartbeat check to information system (if applicable). An alarm is generated when circuit 108 is OFF. An alarm is also generated if there is no response to the heartbeat check. Please check the interface between MD110 and the ICS computer. Either the Interface card of MD110 is defective or the interface on the computer is defective. Try replacing both or the cable itself. Thanks, Sepay |
