	ATCS Newsletter The Evolution of Telephone Cable
		Telephone lines were needed to connect private telephones with the central interconnection facility.
		Telephone cables were needed to replace the large number of aerial wires present in the cities.
		Improvements were continually being made to telephone cable, the use of more and finer conductors in a given cable, lower electrostatic capacity requirements and a larger air to paper ratio of the insulation.

	Requirements for New Telephone Lines
		A decision on whether or not to provide additional telephone lines after January, augment the existing telephone system, or begin obtaining temporary telephone service from GTE should be made with ample time for implementation.
		Move some telephone equipment (e.g., modems and emergency telephones) off of the GTD4600 onto GTE business lines in an effort to extend the useful life of the current configuration until July, 1996 and then replace the system in July, 1997.
		Requests for new telephone lines between July, 1996 and July, 1997 could not be satisfied and the campus community would probably not accept this option.

	Telephone - MSN Encarta
		Telephones are used for casual conversations, to conduct business, and to summon help in an emergency (as in the 911 service in the United States).
		If it is a two-piece telephone set, the transmitter and receiver are mounted in the handset, the ringer is typically in the base, and the dial may be in either the base or handset.
		The receiver of a telephone set is made from a flat ring of magnetic material with a short cuff of the same material attached to the ring’s outer rim.

	telephone lines, and telephone facts
		At the telephone exchange the DC voltage and audio signal are separated by directing the audio signal through 2 uF capacitors and blocking the audio from the power supply with a 5-Henry choke in each telephone line.
		The telephone company wants the DC resistance of your telephone line to be about 10 megOhms when there's no apparatus in use ("on hook," in telephone company jargon); you can draw no more than 5 microamperes while the telephone is in that state.
		The balance of the telephone line is known to your telephone company as "longitudinal balance." If both impedance match and balance to ground are kept in mind, any device attached to the telephone line will perform well, just as the correct matching of transmission telephone lines and devices will ensure good performance in radio practice.

	ePanorama
		Telephone line signal to noise ratio is not as easy to quantify because noise comes in many forms, such as electrical interference from fluorescent fixtures or hiss from the many amplifier stages in the voice path.
		Telephone line equipment are designed for specific 600 ohms impedance (or 900 ohms on some places, varies somewhat from country to country) to match the impedance of the line and the equipment on the other line end.
		Telephones are designed to work in such way that there can be many telephones on the line, but the system is designed so that only one of them can be in use at the time.

	Radio and telecommunications equipment installers and repairers
		From electronic switches that route telephone signals to their destinations to radio transmitters and receivers that relay signals from wireless phones, the workers who set up and maintain this sophisticated equipment are called radio and telecommunications equipment installers and repairers.
		Although most telephone lines connecting houses to central offices and switching stations are still copper, the lines connecting these central hubs are fiber optic.
		As cellular telephones have increased in popularity, the number of pay phones is declining, which also will adversely affect employment of station installers and repairers as pay phone installation and maintenance is one of their major functions.

		A main line is normally identified by a unique number which is the one which is billed.
		If these growth rates are maintained in developing countries, the average telephone density could actually decrease by the year 2000 since the population growth is expected to outstrip the gain in telephone lines.
		Average annual growth rates in the main lines for selected countries between 1983-93 is shown in Figure 2A and the telephone densities in those countries in 1993 are shown in Figure 2B.

	Using the ACCC Dialin Lines
		All the ACCC dialin lines are off campus and you will be charged by the minute on your campus phone bill if you dialin using them (the 666-2001, 666-2002, and 666-9000 lines) from on campus.
		The new-style dialin lines are not in the UIC campus exchange -- you must dial the complete phone number, including the 666 exchange even from on campus.
		So don't use the new-style ACCC dialin lines from an on-campus phone; having your computer connected to the campus ethernet backbone is a much better, faster, and cheaper alternative.

	SignOnSanDiego.com > News > Business -- You dig those overhead lines?
		A four-year dispute over the burying of overhead electric, cable and telephone lines has left some San Diego neighborhoods with sawed-off utility poles and forced the city to pay for costs it has no guarantee of recovering.
		SBC filed its request to charge all customers, including low-income customers who have lifeline service, a flat rate of 77 cents a month per telephone bill in 2007, $1.51 a month per bill in 2008 and 90 cents a month per bill for every month after that until the project was complete.
		Now, San Diego is paying for the design work and conduit for the phone lines to be laid at the same time the electric and cable lines are undergrounded.
