JS>It's not impossible that unplugging everything eventually gave the one
JS>troublesome device a chance to reset itself. The telco might also have taken
JS>your line out of service for awhile to protect the network, they might have
JS>found and fixed a problem at their end during the same period you were 
working
JS>on it, etc.

SBC didn't take the line out of service! I could plug my phone in the
SBC input to my house (with my house totally isolated from SBC)
input and the phone worked OK. This exonerates SBC and makes my house
wiring guilty.

The problem still exists on the original failing line.

JS>I'm not big on faith healing.

Nor I.

JS>I'm not sure if a dead short in the wiring would look like a busy, because a

Yes, it WILL. This is according to SBC's diagnostics procedures. This
will give the caller a busy signal - same as if I was actually using the
line. An open in my wiring would give the caller a ring signal - same as
it I wasn't using the line.

JS>phone isn't a dead short when it's in use. It might be something the telco's
JS>diagnostic robots would detect, and again they might take your number off 
line
JS>temporarily. You said that you didn't detect a short with a meter, so let's
JS>assume that you don't have one in the wiring. In any case, if you did then
JS>moving things over to the secondary jack in the service entrance (I think
JS>that's what you said you did) wouldn't fix it.

When one picks up the receiver it closes a set of contacts (giving the
effect of a short).

JS>I am a little confused about what you did, though. If you moved the live
JS>connection over to the other pair in your house wiring, then you'd have to 
redo

Not so. My house is wired for two lines (two separate 4 wire phone
cables - two separate phone jacks at each outlet). One line was unused.
I just moved everything to the previously unused jack and everything
worked AOK.

JS>the wiring to
each device as well: they typically only look at one pair. (They JS>don't
know the color, of course, only the pins.) That's why I'm guessing you
JS>switched the service over to another jack in the service box, and
then JS>connected the red/green pair to that. It could be that your box
took a hit from JS>lightning, or some such; I think there's some
protection built in.

I opened SBC's access panel - there is NO lightning protection there.
Even though both phone line cables in my house have 4 wires in each
(R,G,B,Y) only two wires are used - the Red and Green. The Black and
Yellow are unused in each cable. This is typical here.
