All phone systems accept Pulse. Some of the more modern ones accept Tone. As I recall some areas of Australia now have DTMF (Touch Tone) available. > 10 or 20 pulse per second? 10 PPS is the std.

Pulse to digit translation 1 to 1. i.e. number 1 = 1 pulse, number 9 = 9 pulses. number 0 = 10 pulses. Despite telco specs, most COs will respond to pulse rates between 8 and 14 PPS, make break ratios of 1.44:1 to 2:1, and interdigit spacing from 400 to 800 ms. Where you get into trouble with this is when you have a flakey line into a flakey switch. Long loops into a sloppy SXS will cause you more grief than a jealous wife. Have fun.
