This object specifies the backward signal requesting the far end switch to sending R2 Group C signals, a further category of call-progress/status information beyond Groups A and B. This is another explicit state-machine transition point in R2 signaling, similar in role to ccasBwdRSXtoGroupBSignals but advancing the exchange to Group C instead, and a misconfigured value here would leave the far end unsure which signal group to send next. After Group B reporting does not fully resolve the called line's status, the exchange might use this signal to request Group C information for additional detail on the call's disposition.
