The ringing pattern is known as ring cadence, in which the high voltage ring current is switched on and off to create the pattern.

In Australia and the UK, the standard ring cadence is 400 ms on, 200 ms off, 400 ms on, 2000 ms off.
In many cases, the cadence consists of a double ring of 0.4 seconds separated by 0.2 seconds, and a two second pause after which the cadence repeats (0.4s on, 0.2 s off, 0.4 s on, 2 s off). In many cases the tone is a combination of 400 Hz and 450 Hz sine waves.
