In the example above, the digit 2 is pulse dialed, followed by the digit 1. Each pulse consists of an A mSec. open and a B mSec. closed, where A will be either 60 or 67 mSec and B will be either 40 or 33 mSec., for a total of 100 mSec. per pulse, or a rate of 10 pulses per second. The interdigital pause time is 800 mSec. The pulse ratios are controlled by the &P command.
