How to get the telephone of a resident Brazilian in London?
I need the telephone or address or email of Laurindo Dos Santos Heleno Junior, resident Brazilian in London has many years. How I can get this? Exists a Guide of Subscribers who I can consult? Debtor!
Question answered by Whateverandeverandamen
I would suggest using www.192.com. This is a directory enquiries service, where you can find people without the full address. It has records of phone numbers, electoral registers and company directors.
If you are unable to find your friend using this, it may be that they have not registered to vote (or are not eligible) and do not have a fixed telephone service or are ex-directory.
On the other hand, you could try relying on the royal mail. They manage to deliver plenty of letters with very incomplete addresses, and your friend has a distinctive enough name to make the process more likely to succeed, so mailing something to them with the address "London" only might work.
Another option would be to contact any Brazilian societies in London, the address is below for the Anglo-Brazilian society. They might be able to help you.
How to raise a low hanging telephone cable?
The telephone cable running between the pole and my house is only about 7ft above the ground. Is there a way to raise it?

Cal your telephone Co. They can fix it the right way for good
What's the difference between telephone line and subscriber line?
A book says a telephone line normally has a bandwidth of 3kHz and the highest bit rate for a telephone line is 34.860kbps(using shannon formula).
It also says the bandwidth of a subscriber line is 4kHz and the upper bit rate can be up to 56kbps(using a sophisticated modem to change the digital signal to analog).
I don't know why the upper bit rate is 56kbps.How to calculate it?
Question answered by Jag
First you are mixing apples and oranges.
A true Modem uses a plain old telephone service line. PoTS
They download at speeds limited by the FCC to 53Kb/s. They upload at 33Kb/s <-- here's your Shannon Formula limit in practice.
A subscriber line is what DSL uses. Digital Subscriber Line.
The things people use for Cable, DSL, FiOS, or Satellite Internet access are not Modems. They do NOT MOdulate or DEModulate. That is the definition of MODEM, it must MOdulate and DEModulate, which is converting a digital signal to an analog one, and vice-versa. They are physical network bridges. They bridge a digital signal from Ethernet or USB; to Cable, DSL, or Satellite maintaining the digital format of the original signal.
How can I record a telephone conversation on the computer?
I am conducting several telephone interviews and I need to record the conversation. I cannot use skype and I do not have a land line.
Question answered by Daniel K
You will need to things - audio recording software:
and a phone line adapter cable:
You said "I do not have a land line" - does that mean you will use a cell phone? If so, there may be adapters for that too but that will depend on your specific phone.
There is a way around that too - just get any computer "clip-on" mic and place the mic near the cell phone speaker (or use speakerphone):
Any way of plugging a microphone into a standard telephone so as to give a higher sound quality?
I sometimes do radio interviews over the telephone (land line). Sound quality is so-so. I have a studio-quality microphone which I use for recording projects (and Skype). Is there any simple way I can plug this microphone into my phone so as to achive a higher sound quality?
Question answered by Daniel K
The other answerer is right but there are audio interfaces for telephone that will allow you to connect a professional mic to a phone:
Sorry it is not cheap but it will do the job.
Compare the telephone network and the Internet.What are the similarities And differences?
Compare the telephone network and the Internet. What are the similarities? What
are the differences?
Question answered by adaviel
(looks like comp. sci. homework :-)
similarities - both use cables or fibre, both allow end-to-end transmission of data
differences - telephone network uses dedicated circuits (while you are on the phone, there is a single link carrying sound from you to the far end). Internet uses data packets that are routed according to best path; there is no dedicated circuit and packets might take different paths and be reassembled later.
At least, that's the stock answer from 1985. Nowadays a lot of phone traffic is VoIP (over the Internet), and there are dedicated light paths on the Internet, so it's a bit blurred.
Does telephone wire produces interfrence or bad reception if it is used for Cable TV reception?
I have used telephone wire in place of conventional coaxial cable to receive Cable TV. But the picture as well as sound quality I am getting is not good. Is it due to telephone wire and should I replace it with coaxial cable?
Question answered by Frank N
Yes you should. This cable does not 'receive' the signal, but instead just carries it from the supply cable to the TV. A coaxial cable is shelded, and its impedance is matched to both the supply cable and the TV over all of the frequencies you need. Telephone wire isn't even close to that.
What are the different model revisions of the telephone from early times 'til present?
I'm looking for all the different model revisions of the telephone, how they've changed since it's early development upto what it is right now. I could really use a link to a webpage or any other references. A timeline-type thing with pictures of the different models is ideal. Thanks for all the help!

A good place to start is "The Telephone Book: Bell, Watson, Vail and American Life, 1876-1976" by H.M. Boettinger. If you can find it, it does a great job at explaining how the telephone came to be, and has some wonderful photos of the early models.
Who installs the Cable TV and Telephone wiring in a new house?
When a new house is built, does the Cable TV company and the Telephone company come and install the inside wiring, or does a building contractor install the wiring, and then have the Utility companies run their line from the utility pole to the house? Does it depend on the situation?
Question answered by joe r
for a new home most contractors want the TV and telephone wiring pre wired inside the walls, so they will sub-contract a low voltage wiring technician to do all of the low voltage wiring - which would include TV and telephone, and depending on the build may also include data networking cable, alarm wiring, intercom wiring, and any other low voltage wiring...
the cable and telephone company would not normally come into a building and prewire durring construction...
the low voltage tech that prewires the house normally will leave plenty of slack in a loop exiting the back or side of the house, so that the telephone and cable company can make there connections there...
if the house is not prewired, then the cable and telephone companies will for an additional installation charge run the inside wiring for the customer - but for the most part, the cable and telephone company will only run surface mounted wiring, which for the home owner is normally not very acceptable for new construction...
How do I calculate the voltage drop from the telephone exchange to my house?
How do I calculate the voltage drop from the telephone exchange to my house, I'm told the supply is 48v along a 0.5mm cable, I live 2 miles from the telephone exchange?
Is the voltage boosted along that distance?
Question answered by Southpaw
If you are in the UK your line will be supplied with -50V on one leg of the line and earth (0V)on the other leg by the line circuit in the exchange.
If you measure the voltage across the line at your house with the handset on you will get 50V or very near.
When you lift the handset it has the effect of putting a 300 ohm resistive loop across the line, which forms a potential divider circuit with the resistance of the exchange equipment, the line, (typically 600 ohms for 2 miles) and the telephone, so the measured voltage at your house will drop to about 10V or so even though 50V is still being supplied.
Modern exchanges are designed for 1500 ohm loop working and supply a constant 40 mA of current, so you are easily within the limits.
In fact years ago in Wales I worked on a line to a farm that was 11 miles from the exchange!
No voltage boost is necessary or provided.
I do not know exactly why you are asking this question, to work it out mathematically you would need to know the exact resistance of each of the 3 components mentioned and that information would be very hard to obtain.
It is easier to measure it at each stage with a meter when the `phone is in use, but only BT can do that except at your house where you can do it.
The 3 things that contribute to line loss are resistance, capacitance, and induction by the way.
Of course if you have been blessed with "fibre to the cabinet" then these will be considerably reduced.
Not much you or anyone else can do to change your line characteristics anyway.
