Icon - wrote in messagenews:telecom22.638.6@telecom-digest.org: Reading Lindsay Pallickal's message about the various wiring color codes reminded me of something I've been hoping to locate for an upcoming project, with no success. About a month from now I may need to install some jacks for 4-line phones, which I am told use the usual trick of putting line 1 and 2 on one jack, and line 3 and 4 on the other. Anyway what I'd like to find is a dual surface mount phone jack -- by that I mean a single unit that contains two jacks that can be wired individually, for example the uppermost one for lines 1 and 2, and the lowermost one for lines 3 and 4. It's a must that the jacks have screw terminals, or failing that, the kind of terminals where you can do a satisfactory job of pushing down the wire by using two screwdrivers.Even Radio Shack sells dual surface mount jacks, but the are almostassured to be crappy, not screw type. There is also an adapteravailable that you can plug into a single jack. The adapter has threepositions, L1, L2 and L1+L2. And while on the subject -- let's say that at the point where the four lines come in, I want to break them out and distribute them to half a dozen jacks, each home run back to the common entrance point. Is there an inexpensive way to do this that uses SCREW TERMINALS (I have never used a punch-down tool, and don't intend to get one for this one project)? Is there a particular product I should be looking for?Beats me. Before any of you purists start attacking me, I'll just say that this is for a residence (of a relative), not a business, and if the proposed solution costs too much (or does not use SCREW TERMINALS) I'll just skip it, and at the meet point I'll just twist all the wires of like colors together and flow solder over them, then after the solder cools I'll dip each exposed joint into the open end of a tube of 100% silicone rubber caulk (the clear kind) for insulation. I have done that in the past and have never had a problem with the soldered joints, but in my dreams there should be a neater way to do this (so you can temporarily disconnect an individual jack without having to physically cut the wires).That should work fine. I haven't been down to any of the local home improvement superstores lately to see what they have, so don't be afraid to mention something they would carry. Finally, I might as well ask while I'm on the subject, if I can't get dual jacks does anyone know of a good, inexpensive online source for regular surface mount jacks that come with the double-stick pads, so you can mount the jacks without drilling holes? I bought about 50 or 100 of them maybe 10 to 15 years ago, and have finally managed to use them all up, but I don't recall where I got them. I'm pretty sure I paid well under a buck a jack, though.I don't know about jacks with the tape on them, but a roll of double-sticktape ought to be easy to find. (Of course, the roll of solder I am using is far, far older -- I bought it when almost all the electronics kits still had vacuum tubes in them. Right after that everything went to semiconductors, so I was stuck with a one pound roll of solder that was too thick for use with printed circuit boards. But it does a bang-up job if I need to splice more phone wires together than will fit into a Scotchlok! I'm now wondering if I will leave this plane of existence before that roll runs out.) :-) [TELECOM Digest Editor's Note: You might want to check out the catalog published by Mike Sandman ( http://sandman.com ) or chat with Mike and see what he can do to help you.
