IDT-Winstar

Any of you know off the top of your head Winstar's config/policy for a customer wanting to accept customer routes only from a BGP feed? Or, a contact that can respond within a couple of hours would be useful too. I've called their NOC. They have no clue what I am talking about. They said email noc@winstar.net. Emailed them. No response...going on 2 days. Checked their website...about as useful as above. Thanks! Tony
