A technique for avoiding accidental actuation of communications system devices which respond to a predetermined pattern of signals. In accordance with the present invention, data to be transmitted through the communications system is scrambled so as to reduce the likelihood of the customer data mimicking the predetermined pattern of signals. At the receiving end, the scrambled customer data is descrambled to its original condition.
