What are the terms of that which has reached Tawatur?

Mutawatir is when a narration gains a huge amount of narrators that it being a lie has basically become impossible, in other words there would basically be no doubt in regards to it's authenticity. But Tawtur has terms, and the terms have been split into Mutaffaq alaih/that which has been agreed upon, and Al Mukhtalaf Feeh/that which there is difference upon. So the question is, what are the terms that fall under Mutaffaq Alaih (متفق عليه) ? and what are those terms which fall under Mukhtalaf feeh (مختلف فيه) ?
