From MICHAEL AFEK
I was most interested to read about John Dowding’s telephone pinging
during the night (Letters, 2 and 16 January) as I too have that problem
– but in my case it occurs at midnight. What I find even more interesting
is that Dowding was assured by BT that it is not engineers testing the lines,
because when I queried it with BT I was told that this is exactly what
it was. One feels that there are crossed lines somewhere.
