I have decided to mux down a DS3 into T1's so that my vendors and customers have redundant access to my site. Here is the situation: Right now my customers/vendors ride the ILEC (I am in Burbank)into my building. I have another carrier with an OC3 running into my building so I wanted to take a DS3 off of that and then MUX that down to T1's so I can offer LEC diversity (and possibly upstream diversity). The alternate carrier has agreed to my plan but I am not sure if there is any regulations or standards that I must adhere to. Also how do I get my customers/vendors to choose me as the LEC when they order the redundant circuit? How do I create a LOA/CFA?
