This object specifies the backward signal requesting the far end restart out-pulsing the entire called-party number, DNIS, from the first digit, rather than resending just one digit. This is a much more disruptive recovery than ccasBwdRSRepeatLastDigit, appropriate when the gateway loses track of its position in the digit sequence entirely, such as after a signaling desync, rather than just mis-hearing one digit. If the gateway cannot determine how many DNIS digits it has already correctly received after a signaling glitch, it would use this signal to have the entire dialed-number sequence sent again from digit one.
