Thank you all for your valuable input. The reason I asked the question is because rain has been given reason for an outage on several occasions I am told. But I see fiber optic equipment and electronics and I traced the cabling and equipment back to fiber optic. I say to the customer 'no, all on fiber, rain should not be an issue'.

The Cat5 extension could be 100 feet, maybe more, and I suppose that is a possibility the phone company equipment does not account for that. From the 'smart jack' there is Cat5 extension to Adtran TA916 so I believe the Adtran could boost the T1 signal as well, if that is the problem, but it all belongs to the telco. This is all tough to troubleshoot and it's been passed over by many others so it's an opportunity! Thank you and I've always enjoyed this board!
