linesmen

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

'cable installers' is the definition.
I can't judge whether this definition defines the answer.

'converted nine elms' is the wordplay.
'converted' indicates an anagram.
'nine'+'elms'='nineelms'
'nineelms' with letters rearranged gives 'LINESMEN'.

Can you help me to learn more?

(Other definitions for linesmen that I've seen before include "keep in touch with flags" , "Telephone company employees" , "Football officials" , "Officials who assist referee from the side" , "Assistant referees" .)
