I would think it would be in the manual, but you have gone farther than whatever the manual would say.

Be happy, laugh , don't worry :toast: .

An OPX circuit is technically not a dry pair.

Youu are correct telemarv that an OPX is not a dry pair. I don't believe any LEC is doing a digital OPX, or a two pair Legend extension, if so that would be news to me.

Any OPX I have seen has been an analog pair with the LEC responsible for amplification of voice and ringing.

I made the assumption that it was an off premise single line extension and you are right, there I go assuming again which is not a good thing to do in this business. Good catch.

Well i'm confused i thought a dry pair was a cable pair f2 connected to an other distribtion pair (f2) since there there is no battery on the line i call it a dry pair (opx)
anyway whether we call it dry opx or a duck

Having reread the post, he is calling it both an OPX and a dry pair.

I don't think an analog extension on a dry pair off the Legend is going to go 5 blocks, but who knows?

What I have understood a dry pair to be is just two copper wires that is rented (usually) for a short distance on LEC phone wiring. Often to the B box, across the street and to another building or some such short distance.


What I have understood an OPX to be is an OLB13C circuit where the LEC provides DC power to take it the distance required and also provides 90 to 105 VAC 20 cycle ringing. They are boosting the circuit from the first location to the end point.

Sorry if I confused anyone trying to be clear.

The more copper you have between points on a dry pair, teh farther you can go. If I were trying to go 1000 feet with 6 pairs, I would put in at least 22 gage and run enough pairs to double up if possible.

There is so much labor involved that copper cost becomes secondary and it has to work the first time.

My guess would be, at least 5 blocks. :dance:

Well, just to muddy the waters a bit. I had an office and then wanted to answer that line at my house also. Telco called it an OPX. It was NOT an extension off the phone system but off the line number. The distance was 7-1/2 miles. Now if it was an extension off the phone system then I would call that a dry pair - whether or not the telco bumps the signal or not. Of course that is what I would call it. Then again - who am I??

I have to agree with NT. I have a golf course that I have set up leasing a dry pair from Bell. We are sending an alarm signal to the owner's house 1/4 mile down the road. When I ordered it, I had to stress that I needed a dry unenergized pair for this or it wouldn't work for what I was doing. They sent a tech out, did some cross-connecting at 3 road pedestals and it works. The monthly bill lists it as an OPX and the order the tech had also listed it as this.

TP, the only way I can get Bell to understand what I need when I order one is to order a TVOSNA circuit. Then they realize that it's a dry pair. If not, they think it's an OPX like NT was talking about. I have a few of them in service. The longest one is 7 km. The MICS is on the front end with an ATA. The back end is connected to a line port of another MICS so they can call back and forth through extension numbers. Works like a charm.
