Broken port in network enclosure

Some time ago I decided to buy a network enclosure for my house. I have recently heard about the usefulness of this device and I wanted to have one in my house. After checking many offers on the internet I decided to buy it in a local computer shop. The prices were lower on the internet but the shipping made the prices equal to the ones I saw in the local shop. I prefer a more traditional way when it comes to shopping because I always like to ask additional questions to the salesman and of course I can get a better view on the object and touch it. So I bought a network cabinet and I read the instructions before I installed it in the living room in my house. Then I checked all the devices: the computer and the connection to the internet, the TV and the phone. The two first were working just perfectly but there was no signal in the phone. The phone itself worked but it looked like it was not connected to the network. My network cabinet had eight telephone ports so I decided to try the other ones. Still there was no signal. I took the network cabinet back to the shop and they checked it. They said that the telephone ports were not working due to some internal defect. They gave me another one that was checked before and this time it worked. Now I have a small network centre at home and it works just perfectly. The network enclosure is really useful stuff.
