Has anyone used BTs line test number 17070

My upstairs line is crackly, so I gave the 17070 test number a try

Recorded voice returns...
This circuit is defined as (your number)
BT line test facilities.
Please press 1 for ring back, 2 for quiet line, 3 for fast test, 4 for fast cleanse or clear down.

So are you supposed to hear literally nothing at all after choosing the quiet line, or just a faint hum?

What do the options 3 & 4 mean?
