telephone pole

I'm a little stuck... Click here to teach me more about this clue!

'employed by communications business' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.

'time for great footballer to retire is perfect? on top of the world' is the subsidiary indication.
I cannot really understand how this works, but
'time' could be 'one' (I've seen this before) and 'one' is present in the answer.
'of' could be 'o' and 'o' is present in the answer.
This may be the basis of clue (or it may be nonsense).

'and' is the link.
