I just recently failed the BSCN test and I have a question. How do you find the CIR of a Pipe that has Ex: 2 64 and 1 128 PVC's? Would it be the least PVC times the # of PVC's or what would be the answer. Any help would be apprecited. Thanks. _________________________________ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
