While excercising the local DMS-100 switch, we encountered
a neat happenstance.

Occasionally, the switch will refuse to allow us to release and re-request
dial tone, no matter what we try, including the 'ABCD' trick.

If we hang on the line, when it finally resets, we hear
a quick sequence of about 5 tones starting at around 800Hz
and stepping up to around 2500Hz.

What are these things? Also, curious how common this occurence
is. We have noticed this a few times before in the last year.
