I bought a new, modular, twin-telephone-jack outlet box
cover, and bridged the two jacks to be in parallel.

I added wire-stubs to furnish twist-together jumpers for the
incoming wire (easier to add the stubs on the bench, than to
deal with the screw-connectors, crouched in a dark corner).

I wanted to check continuity, so I cut a modular cord in
half and bared the wires on one half so I could use an
ammeter to check.

What I found was that black & yellow are reversed, and red &
green are reversed. The colors are that way on the plate
that I bought (short wires with forked terminals in the
ends, under the screw-heads). Is this normal? Does it make
a difference? It seems to me that if it didn't make any
difference, there would be no point to having four wire
colors--two of one color, and two of another color would do
it.

By forked terminals do you mean spade lugs? Ar you sure you didn't
make the reversal when you made the measurements. Looking at things
from the front, they are opposite than when looking at them from the
back.

That said, you can usually reverse R + G, and Bl + Yel. Without
knowing what you are connecting, it is impossible to say for 100%
surety. For example, some pots telephones will not work if their
polarity is reversed. You can answer, and can listen and talk, but
the touchpad to output touchtones will not work. Other phones have
internal bridges that solve that problem.

Telephone equipment transmits balanced signals - i.e. only the voltage difference between the two wires matters for its operation, not the actual polarity (which is very often flipped, just like in your case). In other words, it will work.

The yellow and black wires are for a second line. If you don't have a second phone line, just disregard the yellow/black pair.

That was probably designed to be used for a DUAL phone system. (Two
phone lines). R + G are always the first phone line, and Y + B are the
second line.

Since you wanted both jacks on the same line, you had to change the
wires. So what's the problem?

Nope. It was just a modular extension cord that I could

check color to color with an ammeter.

I installed it, and it, and both DSL modem and the telephone

There are 4 ways you can crimp on the RJ plugs and the people who make

The phone really doesn't care unless it is an old genuine Bell/Western

Then you must have lucked out and got the right connections. IF you

and see if you can still touchtone. I'm not sure if it will still

You know, I just learned that on sci.electronics.repair.

I've been using the terms for about 50 years, and I thought the ring
was the wire the ring came in on, and the tip was the other one, maybe
because it tipped some circuit when the voltage got high enough.

I only figured it out this past summer when I asked about what turned
out to be callled a TRR plug, a tip, ring, ring plug.

I'd be very surprised if what you bought is backwards. I've never
seen that Unless you bought the stuff at a dollar store. That's the
kind of thing they would sell. (Check out Jay Leno's shopping trips
with various mismarked things people send in from dollar stores.)

That said, I never worry about polarity until somthing doesn't work,
and it's been 15 or 20 years since something didn't work (that was a
trouch tone phone that wouldn't make tones unless it was connected
right, or the jack was wrong.)

I suppose if the polarity was reversed between two phones and you held
one to your left ear and one to the right, you'd losse a lot of bass.
As with stereo speakers. But that hasn't come up.

Two miles of 26GA wire (one mile from the CO to the house) is around
400ohms, so that's 120mA into a short. 24GA wire would be around
250ohms. Scale from there.

surety.

Telephone and computer DSL line.

For example, some pots telephones will not work if their
polarity is reversed. You can answer, and can listen and talk, but
the touchpad to output touchtones will not work. Other phones have
internal bridges that solve that problem.

Not exactly sure how you have it wired.
Or where you are.
In the USA, red/green is what most people use.
The black/yellow is for a second phone line.

If you are using old wiring. They moved away from quad station wire some
time ago.



Are you sure your cable is wired with the proper colors?

I bought a new, modular, twin-telephone-jack outlet box

I added wire-stubs to furnish twist-together jumpers for the
incoming wire (easier to add the stubs on the bench, than to
deal with the screw-connectors, crouched in a dark corner).

I wanted to check continuity, so I cut a modular cord in
half and bared the wires on one half so I could use an
ammeter to check.

What I found was that black & yellow are reversed, and red &
green are reversed. The colors are that way on the plate
that I bought (short wires with forked terminals in the
ends, under the screw-heads). Is this normal? Does it make
a difference? It seems to me that if it didn't make any
difference, there would be no point to having four wire
colors--two of one color, and two of another color would do
it.

There are 4 ways you can crimp on the RJ plugs and the people who make
up cords only care about 2 (reversing polarity or straight through)
The phone really doesn't care unless it is an old genuine Bell/Western
Electric phone with the mechanical ringer and touch tone.
They won't "tone" wired backward.

One of the phones *is* an old "Princess" model, with lighted
pushbuttons in the handset, and a real bell for a ringer. It
seems to be working fine.

The later versions of those were LED and line powered.

If you have a 6-wire cable (apparently the only thing the local Lowes
sells), the third pair is blue/white.

I've also seen 3-pair cable that had green, blue, and orange
(solid/stripe) pairs. Also 3-wire cable (red/green/yellow, no black).

Geeezzzzz, I dont think they've made lighted dial phones since the
1960s.



I got a lighted-dial phone in my first apartment (about 1980), however
it was powered by the phone line and lit only during a call.

Someone had left an old transformer connected to the yellow/black wires.

I seem to remember something about an additional wire (yellow?) used for
ring control on some party lines.

How many amps for phone, or DSL? AC or DC?

I think it is something like 20ma that causes the line to go off hook

The line is nominally 48VDC on hook and pulled down around 5-10 off
hook.


I checked the line here, about 10 years ago. I got 50VDC when on hook,
and 6VDC when off.

The max they say they will source is around a half amp but they don't
say what voltage that will end up being. I bet you can't really get
that much.

Don't forget that you can only have so many real phones on your phone

There was no other power source for the bell, and they needed to be loud
enough to be heard a long way off.

If you go over that number that phone or all the
phones won't ring. Modern, phoney phones have RENs like 0.2.


The REN on my cordless phone is listed as 0.0B . It COULDN'T be drawing
no current at all.

BTW, I now have phone from the cable company. I don't know it's REN
capacity, but it's working for me with 2 "real" phones as well as the
cordless and a 13-year-old DVR connected.

In last house, in 70's I had at least 7 phones hooked up with 4 coil
ringers. Some phones had no ringers or disconnected.

Today, I have 2 coil ringers along with electronic phones. I don't know the
spec on my comcast interface. Back in the day, you were supposed to notify
phone company of added devices.

Greg
"back in the day" you were not allowed to install "customer owned"
telco equipment. That changed to you could, but you paid for every
extra device - you were supposed to let them know- and if you didn't
they could tell by the ringer equivalency, and charge you anyway. In
more recent years, customer owned telco equipment is the norm, and you
pay for the "service", not by the device.

Or a diode or two are blown. That happened to an old (PCMCIA) modem
of mine. Actually, it came that way. I used to carry a coupler and a
reversing coupler when I traveled.

And back in the '60s, our Phone Company charged an extra $0.50 monthly
fee for a lighted dial.
