Cobra oddly twisting around channel (3)

'channel' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'cobra oddly twisting' is the wordplay.
'oddly' indicates alternate letters (letters in odd-numbered positions).
'twisting' says the letters should be written backwards (letters twist back).
The alternating letters of 'cobra' are 'cba'.
'cba' written backwards gives 'ABC'.

'around' acts as a link.

Can you help me to learn more?
