BGP Communities for H.E. and Deltacom?

Hi there,

Any one know what are the acceptable BGP communities are for H.E. and
At one of our POPs we¹re using an aggregate provider and I need to help them
to fix some prefixes that I am announcing from another POP (ie. Lower the
metric so only use the backhaul for failure of the other side).

I was hoping that they would be listed on the One Step¹s bgp community
listing. Any links to such documents for both HE and Deltacom would be
great and would be much appreciated. Thank you,
