Where to start...I am an experienced cabler but am new to OSP. I consulted several experienced cablers on this project. I have run 1100' of 6 pair Superior Essex CAT 3 22 AWG in 1" Sched. 40 Conduit with 2 pull boxes. I have Circa 2606's on each end and IROB's behind those (LUC-146E). I have grounded the primary protection with 6 AWG at both ends (far end to the ground rod and near end to building steel and grounded the aluminum sheild with 3M 4460's to the second ground lug on the Circa primary protection devices with 12 AWG. This is for one Avaya Definity 6408 digital phone. The problem is the phone won't come up. I get around 47.6V on a multimeter at the far end of the run and the phone seems to try to come up but will not fully come up. When I first installed the primary protection (the IROBs hadn't come in yet) I was able to get the phone up but with heavy static only at the far end. When I put the IROBs in today I now cannot even get the phone up. HELP..I've read all the other posts that looked like they related but have not found any advice that I haven't already tried with the exception of testing the resistance of the ground. I have even tried using another port on the Definity. Any help would be much appreciated and seeing as how I'm into this job for about $1000 bucks would sleep better if I can get it completed!! THANKS!

I'm going to move this over the the Avaya/Lucent forum where you stand a better chance of getting guidance. My guess is that you are pushing the limit on capacitance. Let's see if any of the folks there can give you a better answer.
