Hi group,

I have a home run system with all OpenHouse equipment - 8-way phone hub, Linksys router and coax-video distribution center. The system has been up and working for a year, but I've got a handful of wires that I have not terminated and I'm trying to clean them all up and get this done once and for all.

One wire, in particular, has me puzzled. It's a cat5 wire and I have installed and crimped 2 adapters, but whenever I plug it in to my H619 phone hub, all lines in the house go dead. When this new cable is plugged in, I look at my cordless phone and it says "extension in use" and when I unplug this new cable, the dialtone will come back.

I removed the plug and re-crimped another one, just incase I made a mistake, and the same thing is happening.

Any ideas what I am doing wrong or what the problem might be? If it makes a difference, I wire all of the cat5 wires in the house the same, so I can later decide to switch between the phone hub and Linksys router, depending on what I want the outlet at the end to be. This connection will most likely be a ethernet connetion, but I usually use the phone hub to test I have the right end of the wire, as it's easier to walk around with a phone as a tester than a computer. :)

Thanks!
Aaron

amheck, go to Home Depot. Buy the Ideal cable tester, it's about $50 and will tell you if you have any shorts, opens, or miswires. It's not by any means the end-all tester or enough for cat5e signal quality/data testing, but it will tell you if you connected things basically right or not. In this case, it sounds like you didn't, and this would be the tool to tell you whether you have such a problem and what it is.

Thanks. Actually, I have to go to home depot tonite anyways. I'll take a look. I am by no means an expert with this, but I have terminated quite a few wires in the house, and I just can't understand what might be wrong here...

I use a simple network cable tester for any cable I build. If I'm having problems that I suspect may be cable related, I fire up my TDR and check the actual characteristics of the cable.
