****Emergency**** T1 Wiring Install

[brogers]

I need to get this T1 setup so I can surf Anandtech faster.

What is the correct wiring from the outside where ma bell dropped off the line to inside my house where I setup a keystone jack? Here is what the box outside my house looks like....

Box outside my house image

The keystone jack is color coded for a typical 568B wiring. I just need to know what terminals go to the colors on the keystone jack.

Pins 1&2, 4&5 are your two active pairs.

It should be a stright-through chunk of UTP or premesis cable between your jack and the CSU (internal or external).

Good Luck

When I put my T1 at my house a few years ago (company paid for it - Nice to work for a telco), they extended it to my office - I just had to plug in my router. Might be worht looking into to see if it's part of the initial cost.

Without getting too techy the easiest way to take care of this whole issue is to run a 568b cable from the NID to the destination in your house. That will pull the signal from NID just fine. It rides on pins 45 and 36 Good luck. If you are makeing the ends on the cable make sure you use the 568b wiring standard. If you dont you can get worse from attenuation and speeds.

T1 is delivered on 1&2, 4&5.

What's 568b cable? UTP? Premises cable?

There actually is no NID with a T1. The line is delivered to a "smartjack" most of the time (can be looped by the provider for testing).

Your right I am sorry for the incorrect pin out not sure what I was typing.

568b is a UTP cable. (patch cable) 568A is a standard used by the military that switches the 1,2 & 3,6 pin (Not common), but I am not sure if it will have any performance issues. Best to go with what you know will work.

Yes and there should be a smartjack (assuming at the nid), but every smartjack I have ever seen has a RJ45 jack that if you plug the patch cable that into that jack and end at your switch, router or whatever you intend to do with it you will be good.

What is a NID? You mean NIU (network interface unit)?

How can one plug a rj-45 (actually I believe it is an rj-48c cable) into a switch unless it is an rsm module in a switch?

Umm, no; 568A is not a standard used by the military...its just a standard. Its not like the military is the only one who uses it. 568A on one end and 568B on the other end is plain old crossover cable. You might want to go read up on cabling standards.

Of course 568A is not a military standard. If 568A was a military standard we as the public would probably not have access to it.

Do you deny that typically on military bases 568A is not common? Every military application I have ever done has ALWAYS required a 568A patch panel. Is this requirement because we were crossing over the wall end. No it was not. Matter of fact incase you did not know they make jacks that are 568A aswell just for applications such as these.

The user brodgers is asking what I assume a basic question. So it is up to others to try to give him info not to confuse him. That is what I was tring to do. It is clear that you know what to do. Please do not try to insult others for helping. If he wanted statistics and in depth info he would have listed that in another question. If I could have help in that question I would have. If I did not feel comfortable with it I would not.

I can only assume that what the 666 stands for in your name so why dont you keep your evil attitude out of a helpful form?

Cnuke: You information is marginal, at best. It's great that you're trying to help, but some of what you've posted is just flat wrong (i.e., "not helping").

The "box outside the house" has an RJ45/48 style jack.

If Brogers runs a four pair UTP or Prem cable (as a straight-through) to a wall jack, the wall jack is color-coded, just terminate all four pair (as would be normal) at the plate according to the color code of the plate/jack. Each vendor has their own way of internally connecting the pins in the socket to the punch-down on the back of the plate, so there is no specific order ... just follow the color code.

The jumper from the wall plate to the CSU/DSU would be a straight-through UTP or Prem cable. Depending on the CPE, it may be necessary to terminate the CPE-end of the cable in a DB15 male connector (if it's going to a router, probably not): the upper and lower pins at each side - I think it's 1,9 & 8,15 .

If the intention is to terminate the cable from "the box outside the house" directly to the CPE (CSU/DSU - no jack or wall plate)), then terminate it using the same (568a / 568b) pair-ordering as the end that connects to "the box outside the house."

That's all there is.

Premises cable: two twisted pair, each pair shielded, with a separate overall shield (both pair) in a "durable" jacket.

FWIW
