We have a plant running 6.3 on an AW51D, that we are unable to set the MPOLL to 7. It is all fiber between the remote cabinets and we are running CP40 process. This problem is not isolated to one CP. When we try to run at 7 we get intermittent buss failures, finally change the MPOLL to a 5 and things run fine except it cost me 10 to 15% on my loading. Foxboro did the construction on this project including the fiber buss. I have questioned several time the terminations and layout and they assure me that it is fine. A CAR was submitted over a year and a half ago with very little effort on their part to fix it. Have had two calls from TAC wanting to know if they could close the CAR and my response has been no. Has anyone else experienced this problem? **************************************************************** A lack of planning and communication on your part does not constitute an emergency on my part!
