t1 hard loop plug

Is there a tutorial on how to make a t1 hard loop plug so that telco can run a loop to my Cisco router? I see that you can buy it but it is around $7 a piece. I am sure I can make it for half the price. Thanks

It looks like for building a cable instead of a plug where I can plug the existing T1 cable connection in so that telco can loop up the Cisco router. I guess I am looking at how to build something close to this: http://www.google.com/products/catalog?q=t1+loopback+plug&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&um=1&ie=UTF-8&tbm=shop&cid=5640626813600199250&sa=X&ei=LVi-T529JuqI6AGWtbRg&ved=0CIIBEPICMAE

Is the cable going into the router go through a patch panel?  If so, then you just make the cable from the link kenboonejr gave you and then connect that to the patch panel.

That will test everything except the patch cable you use from the panel to the router.

Now, if there is a cable straight from the telco's dmarc to the router, then you will need to create something like your link shows.

You could get a coupler (either RJ-45 or RJ-11) tear it open, cross wire as needed.

You might be able to make it using a RJ-45 to DB-9 converter and cross wire the pins that go into the DB9 side.

However, it going to cost you anywhere from $2-6 to get either a couple or RJ-45 to DB-9 converter.

Just about the same price as the little device you posted.
Your help has saved me hundreds of hours of internet surfing.

Cable coming from the T1 smartjack straight into the WIC card of the router.

Yes I did that before. But the hard loopback is easier as the site contact can just plug it in and have telco loop up the WIC card. Thx

Agree with pergr. Take an RJ45 jack. Wire pin 1 to pin 4 and pin 2 to pin 5. Plug it into the smartjack port. The other way to do it is to wire same pins on an cat5e insert and plug your patch cable into that. I keep both on me in my bag.
