This is the return level as recorded on the last response received on this receiver. This value only applies to the RF port types; all other port types should return noSuchName Error. If the port has not received a response and therefore has not recorded a reverse return level then this objects shall return -999. When the return level falls outside acceptable limits, as indicated by the properties of this value, the offending units hmtsDevComStat shall indicate a bad return level. This value is a placeholder to globally affect the properties that really apply to the return level value in the hmtsDevTable. In all cases the HMTS shall set hmtsDevReturnLvl for the device to this as received level upon receiving a valid massage. The property thresholds and enable when set using this object shall be used for all hmtsDevReturnLvl in the device table using this receiver. This object never reports an alarm, hmtsDevReturnLvl does when the thresholds of this object are tripped. Use hmtsDevReturnLvl threshold properties to affect a property change for an individual device. This object has a threshold property in the propertyTable as defined in SCTE 38-1 (formerly HMS026)
