How technology has changed dating 05 Feb Finally, at 8pm, my phone buzzed. I schlepped all the way across the city — only to spend the next three hours with Paul and about six of his friends. We follow the new rules as assiduously as they do, are just as uneasy about being pinned down, just as likely to be the texter as the textee. Actually phone someone up to ask them out and agree on a date at some point in the future and put it in my diary? What if I get a better offer? Instead, millennials like to keep it vague. Ours is a generation of contradictions. Why make a phone-call or suggest a date when you can send a non-committal text that merely dangles the possibility of meeting? But at least one of you can end up feeling confused.
Hook Up Wire
I just like to share when I resolve an issue, which I did, and it was simple. I know others have posted helpful info, but for those that have no idea what a MAC, RJ11 or “port the wiring” means, I’m hoping to help. As well, some short info on having TWO modems You can plug your PC or Router into the new modem it will work , as well as your ONE phone, and get it all working before trying to keep your old modem as well.
Believe me, it’s much easier this way. Be sure you directly connect a home phone standard or wireless into the LINE 1 phone plug in the back of your new modem that was provided.
Using 2 Sounding Units (chimes) To hook up a second sounding unit. Connect a 3 wire cable from unit one to unit 2, Screw 1 wire from unit one goes to screw 1 of unit two.
General technical details of telephone line Surprisingly, a telephone is one of the simplest devices you have in your house. It is so simple because the telephone connection to your house has not changed in nearly a century. If you have an antique phone from the s, you could connect it to the wall jack in your house and it would work fine! Plain old telephone systems POTS telephone line consits of one wire pair which carries full duplex audio and the operating current for the telephone.
The telephone connected to line is powered from current limited 48V power source, so phones on-hook, should measure around 48 volts DC. Practically the opearating voltages of telephone systems can vary from 24V to 60V depending on the application, although 48V nominal voltage is the most commonly used. Telephone applications often require and use positive grounding in the central office, where the positive conductor of the 48V power supply is connected to earth ground. The telecommunication industry began the positive ground convention in the s and many telecomm companies still employ the traditionally positive grounded system.
The line feeding voltage was selected to be negative to make the electrochemical reactions on the wet telephone wiring to be less harmful. When the wires are at negative potential compared to the ground the metal ions go form the ground to the wire instead of the situation where positive voltage would cause metal from the wire to leave which causes quick corrosion. This means that generally when telephone is on-hook, one telephone line wire is quite near to the ground potential and other one carries V.
When telephone is put off-hook the voltage beween wires going to telephone drops down to the 3 to 9 volt range and typically a current of mA will flow through the telephone.
Do it yourself home telephone wiring.
Lamps With the exception of the lamps, all of the above are a safety hazard in addition to being very likely to make the phone line malfunction. In particular polarized capacitors or any cap rated at less than volts DC working volts , and batteries of any kind, should be avoided because of the potential for a an explosion. The other devices are merely a fire hazard. The resistors used in the real telephone circuits must have enough power handling capacity and be used so that they do not cause fire hazard non-flammable resistors situated away from flammable materials.
The simple things are that the telephone line is a balanced transmission line which can have up to ma of DC current from up to 56 VDC actually in some cases up to 90 VDC and up to VAC RMS ring voltage in the way of various voltages and currents.
I’m trying to hook up a old light I got and there are 4 wires coming out of it. The are white black green and red and its volt. What I’m connecting to only has 3 wires that are black white and green.
This article featured Engressia and John Draper prominently, synonymising their names with phreaking. The article also attracted the interest of other soon-to-be phreaks, such as Steve Wozniak and Steve Jobs , who went on to found Apple Computer. In the first issue of YIPL, writers included a “shout-out” to all of the phreakers who provided technological information for the newsletter: YIPL believes that education alone cannot affect the System, but education can be an invaluable tool for those willing to use it.
Specifically, YIPL will show you why something must be done immediately in regard, of course, to the improper control of the communication in this country by none other than bell telephone company. TAP ended publication in due mostly to a break-in and arson at Tom Edison’s residence in A controversially suppressed article “How to Build a ‘Phone Phreaks’ box” in Ramparts Magazine June, touched off a firestorm of interest in phreaking.
This article published simple schematic plans of a “black box” used to make free long-distance phone calls, and included a very short parts list that could be used to construct one. Bell sued Ramparts, forcing the magazine to pull all copies from shelves, but not before numerous copies were sold and many regular subscribers received them.

How can I prepare my inside wiring for DSL installation? Then you will want to explore all possible paths between those two points that would be the shortest and easiest to run a wire. Try to route away from any kind of power wires or power using equipment inside. Disregard all the existing telephone wire, because you will want to run a new wire for the DSL line for optimum performance. If you have that extra wire, preferably Category 5 wire for noise resistance, the installer will be more likely to install a jack on the computer end for you.
In most residential phone wiring, the cable contains four individual wires. Most phone wire installed in the U.S. during the second half of the 20th century is of the following kind: Four-strand wire: The kind of wire shown above has recently become obsolete. For all new telephone wiring projects, you should use Cat 5 .
Jan 2, Just confirming what the others said A single phone line uses one pair, the inside two wires red and green by phone standards. A second line can be run on the outside pair black and yellow also, but it requires a special two-line phone. Most devices nowadays only have the middle two wires connected even. All you need to do is wire up the red and green terminals in your phone box like j-sta’s pic to the red and green terminals on your internal phone jack.
Like j-sta said, the DSL signal is on the same pair as your analog phone signal, so you don’t need a second line unless you actually ordered your DSL on a second phone number but you do need filters to keep the DSL signal out of the phones.
Setting up a VoIP GW
It’s an analog telephone that can use either a hand cranked generator for signaling Local battery another phone or the operator, or optionally can use the hook switch to signal a central office Common Battery. In either signaling method there needs to be a couple of “D” batteries in the phone that are connected to the microphone when the Turn To Talk switch is activated on the handset. Unlike military radios, where you can not listen while you are talking, the EE-8 is a full duplex phone just like a Plain Old Telephone System phone, although you do need to use the Press To Talk switch to turn on the talk batteries, and more important when the PTT is released the battery circuit is opened, thus saving the batteries.

This page will help in understanding telephone wiring for your home, and give you tips on installation and troubleshooting your home do it yourself telephone wiring. At first glance all the colored wires associated with your telephone wiring may seem confusing.
Also need to find a wiring diagram to check that the handset is wired up correctly. Also, when I call the line, when I remove the handset from the hook, it does not answer the call. Taking the handset off the hook is supposed to do what electrically? Thanks Carl Try to kill two birds with one stone. No, this board was the last of the dumb boards – it is line powered, and unlike the newer COCOT boards programmable , needs no external power.
For handset wiring, see the information in that link I gave you earlier to the Sundance site. There is a hook-switch in these which provides the switching for the handset- in this one, it is likely a micro-switch – if it were bad, it could conceivably cause the problem. Handset – the crack shouldn’t cause a problem, but bad elements or conductors in the cord could. You might be able to break the weld with a strap wrench, but there is also a possibility the plastic will break rather than the weld.
They are normally replaced as a unit. However, I have managed to break the weld in a few of them successfully using a removal tool I have here, and also using a strap wrench. I am surprised actually we haven’t figured out what its problem is – the last one we were asked about is now working, though with slightly low volume. I suspect now we should be looking into a phone fault, such as bad handset or bad hook switch, both in the front cover

Each pair consists of a solid colored wire and a white wire with a stripe of the same color. The pairs are twisted together. To maintain reliability on Ethernet, you should not untwist them any more than necessary like about 1 cm.
The telephone network. In order to understand the many concepts represented in the public switched telephone network (PSTN), it is helpful to review the processes that take place in the making of a single call on a traditional wired telephone.
Telephone Circuits Telephone In-Use Indicator When a new computer modem enters the household, the demands on the home phone line skyrockets. The Internet surfer can use phone time on a par with the most talkative teenager. And the computer modem user can be quite sensitive about his privacy: The phone wiring may be modified so that the modem is always in control by connecting the phone line directly to the modem and connecting the rest of the phones to the modem’s “phone” jack.
But this solution gives the computer user too much power over the phone line and it doesn’t solve the problem if two computers share a single line. Here is a simple blinking LED circuit which will alert users when the line is in use before the receiver is lifted. The circuit loads the phone line so lightly that it meets the on-hook telephone equipment leakage specification and the short lamp flashes draw very little current from the nine-volt battery. One of these devices may be placed at each extension without significantly loading the phone line.
The circuit is connected to the red and green wires for a single-line system or the yellow and black wires for the second line in a two-line system. Polarity doesn’t matter, thanks to the full-wave rectifier. In order to preserve your phone line balance, do not power this device from a line-powered power supply. Only use a battery as shown and insulate the battery and circuitry by building the device into a plastic case.
Do not ground the circuitry.

White Black Green sounds like a “found wire” The only way to know the correct way is to identify which conductor goes to which pin on the socket. On an RJ11 socket, probably only the middle pins are used Now with additional accessories, which is red and which is green MAY matter, but for most applications it doesn’t matter if red and green get interchanged along the way. Here’s another tip you may find useful. On a 3-pole wiring, such as the wiring to an electrical socket where one side is always on and the other side is on a switch, you will have a fourth wire Red.
Red is ALWAYS “Hot”, and is usually the one in the bunch to be fed from the switch, however there is nothing in the code that says that red must be the switch. In some cases, an electrician may choose to use Red as the always on, while using Black as the switched hot wire, or even have both black and red as live hot wires that are always on.
Wiring a Doorbell System (NEC 2002)
If not, the Direct Current DC from your Central Office will find a short circuit across the ringer coils and will register a “false Busy. This frequency was derived by the average output of a hand-cranked magneto. Magneto telephones were once the most common form of telephone. Since the batteries were usually to be found inside of a magneto phone, or close by, the older form of telephone is called a Local Battery Set.
When battery power was located in the Central Office, telephones were reconfigured to Central Energy, or Common Battery style. With battery voltage ever-present on the telephone line, there could be no path through the telephone set if it was not being used, or On Hook.
Background The EE-8 was used throughout WW II and into the Korean conflict. It’s an analog telephone that can use either a hand cranked generator for signaling (Local battery) another phone or the operator, or optionally can use the hook switch to signal a central office (Common Battery).
Here are some more pictures of an original CarterFone click to see a bigger version: He says his is an acoustic coupler with a twist, a bar that both opens the line and dials the number. A standard set is placed in a tray, and a bar goes over the switchhook cradle. The mobile user had a telephone dial that pulsed a tone, this pulsed the bar and thus dialed the number.
The radios were half-duplex, this is to say, you could talk or listen, one or the other. The middle page includes a picture of an IMTS type phone sitting on the “hump” by the front seat of a Cadillac RCCs usually also offered pager beeper service, before the Phone Companies got into it.. In the ’60s through the ’70’s an acoustic coupler was often used for data usually baud, per Ed Cummings , by placing a regular telephone’s handset into rubber cups the acoustic coupler.
Beeps from the other end of the line would be changed into serial data going into some kind of computer. Serial data from the local computer was changed into beeps and transmitted to the other end of the line. Since the data was just audio beeps, kind of like Morse Code , there were no extra exorbitant charges for data use from the Phone Company, and there was no equipment to rent since there was no wired connection to the phone line thanks to Tom Carter, and the Carterfone decision.
A Data Modem CarterFone is a logical extension of the original CarterFone, which used the acoustic coupler to patch voice from a phone call into a two-way radio and vice-versa. That’s 12 or 24 conversations at a time.
