An LOScondition exists.OOF Out of Frame Yellow ON – At least one OOF was detected duringthe sampling period.OFF – No OOFs were detected during thesampling period.ALM Alarm Yellow ON – An alarm condition is present on thenetwork/DSX/PRI interface.OFF – No alarm condition is present on theNetwork/DSX/PRI interface.PortOK OperationalStatusGreen ON – The interchange circuits for the port arein the correct state to transmit and receivedata. For 9128 units (which have two dataports but one related LED), at least one of theports is enabled and active.OFF – The port is idle. Occurs if the port isdisabled, or if the port is configured to monitorDTR and/or RTS and the lead(s) is notasserted. For 9128 units, both ports areenabled and at least one is inactive.Models 9520, 9520-ILM, 9820-45M:TD Transmit Data Green ON – At least one transmit frame was receivedfrom the DTE during the sampling period.OFF – No transmit frame was received fromthe DTE during the sampling period.RD Receive Data Green ON – At least receive frame was transmitted tothe DTE during the sampling period.OFF – No receive frame was transmitted to theDTE during the sampling period.Table 3-1.
