TGCONF=(MULTI,STANDBY,nn) designates that a subarea station is to be used for hot-standby and congestion relief. The subarea transmits data to relieve congestion in the transmission group configuration if queued data reaches the value specified by nn. nn indicates the percentage reached of a threshold specified by the totthresh suboperand of the ERn keyword on the associated PATH definition statement. The totthresh suboperand defines the total number of bytes that can be queued for transmission to an MLTG before NCP takes control measures to slow down the TG traffic. Valid values for nn are 3, 6, 12, 25, 50, 75, 87, 93, 97, and 100. NONE designates that the station is used only for hot-standby and not for congestion relief.
