Table 5 shows some call progress tones with on/off times; 0.25/0.25 being 250 ms on, 250 ms off on a repeating basis. For example, dial tones as shown in the table are usually "on" continuously and last until the first dial digit is received by the switching system. Line Busy, on the other hand, is turned off and on at a rate of l Hz with a 50% duty cycle, or an interruption rate of
