DSL problem and solution

Probably .... :rolleyes:

It was an older term that I've heard over 20 years ago, when they were first starting to use the interface jacks. Some of the first ones we installed were indoors, usually at the first jack.
 
The only thing I thought it could possibly be was the carbon arrestor in the NID that was in their space.

If it was the same type NID that you have pictured it does not contain carbons, the protectors would be either solid state or gas tube. Those NIDs sometimes do contain a half ringer for the purpose of line testing which is always bridged actoss the line. Apparently there was a problem with the protector mod for that line. Since it was the DEMARC you should not have done what you did but rather called in a trouble ticket, panicked customer or not. Wasn't your problem, tell them to deal with it.

Sometimes being a telephone tech has it's benefits.

Now if you had just said "demarc" all of that would have made perfect sense to me. ;)

But, if Marc said demarc, he would disappear. :grin:


Like when someone asked Descartes if he wanted some tea, and he answered "I think not." *POOF!*

Hal, it wasn't the demarc, which was part of what I was trying to explain. The demarc was in the phone room, right after the Cook block. This was just a NID, used on the end of a 6-pair radial cable coming from the phone room. Someone used a NID instead of a punchdown block. It was customer owned cabling, but it was probably originally installed by the phone company.

Ahh, well in that case I would have just removed the whole damn thing and replaced it with a split 66M block with bridging clips. Much easier to connect your wiring to, no? I hate those binding post screws though the newer ones use a "no tools required" lever.

I thought about it, but I didn't have one. To get to it, I had to go through the ceiling and sit on a platform on top of the bathrooms. A couple UR connectors solved the problem. Truthfully, I wasn't sure what the problem was at first, so jumpering around the arrester with UR connectors was just a lucky guess. I have no tools to test the quality or presence of a DSL signal.

At Bob Badger's suggestion, I just bought a cheap DSL model off eBay. It's about the size of a deck of cards. It hasn't arrived yet, but I'm going to tape a few 9volt batteries to the side to make it portable, and use it as a DSL connection detector.

Most of us don't. Normally you would use the customer's modem to see if it links up. If it doesn't I check my wiring and filters (if necessary) in the right place then call tech support, same as for any other issues. They are capable of diagnosing any problems remotely and will tell you what to do. Normally that's the customer's responsibility or their geeks.

I'm not sure you can use just any modem beyond checking for linkup because of a modem's ESN. If the account has already been established it will only work with the customer's modem.

Beyond seeing that it links up I usually don't get involved, although I have set up new accounts for some customers. Many DSL providers require reprovisioning of the modem and router to work with each other if you are going to connect to a network with more than one computer. You can't just plug a router into a DSL modem like you can with a cable modem.
