I've assisted in jobs when a T1 line was to be setup but this was the first time I completed the configuration myself from the beginning. This was a friend who just moved into a new building that was apparently in an isolated area infrastructure wise. The two options they had in terms of internet access were a Verizon t1 line and an att uverse line with a max 1.5 Mbps dl speed. They opted to sign a t1 contract before approaching me so that was what I was tasked with.
Verizon t1 line
Smart jack installed by verizon
Client supplied AdTran 3200 v3 that I then configured
Configuration went well as far as I could tell. I could connect to most websites I tried to although I could definitely tell there were some issues that I perceived as speed issues. Granted I will admit I don't have a 100% grasp on the relative speed a 1.5Mbps down connection should "feel" like as my home is 30 Mbps and my office runs at 50Mpbs. Sites like google or craigslist loaded more or less instantly while other sites like cnn or espn loaded significantly slower, in my mind probably because of all the extra content like images and videos and flash based menu's etc.
My issue now is that they are having problems connecting to certain sites. Sites like bofa.com and kayak.com are unreachable, typically only loading only html minus pictures and some formatting. Other similar industry sites, i.e other banking and airfar sites, load up without issue. The problem sites can be pinged just fine. Basically I need to determine if this is a configuration issue(on my part) or a connection issue(on verizon's end). If this is indeed configuration issue, can someone point me in the right direction as far as where to look for problems in the adtran. These issues persist whether I am using a client hooked directly into the adtran or the internal side router configured for DHCP. If this is a speed issue where the actual dl speed is causing the problem, is there anything I can do to help? I am listing some of the information Verizon provided me should you see any issues. The information below was scavenged from multiple emails and a piece of scratch paper that my friend had notes on when calling verizon. Thats actually the only time they were given a DNS server(and only one). If I had to take a guess at what is causing the problems I would say DNS? It gave me the most issues and it was the only piece of info I didn't have direct from a verizon tech. Any help is appreciated. In the meantime I am attempting to double check the supplied values via verizon.
