This object specifies the backward signal indicating the R2 register has enough address digits and will not proceed to send Group B signals at all, with the call instead being charged only once answered. This is a distinct outcome from ccasBwdRSXtoGroupBSignals; here the exchange explicitly skips subscriber-line-status reporting, so its presence changes how a gateway's call-progress and billing logic should behave, since no busy/free indication will follow. A call routed to a destination where line-status signaling is not supported might receive this signal instead of a Group B response, telling the gateway to simply proceed to ringing/answer without expecting a busy/free indication first.
