we use twisted pair wire for a phone becaues twister cable is 2 form shilded and unshilded unshilded cable is good for transmission both data and voice and its frequency range is fast it is consist 2 conductor.

∙ 11y agoYes - it's still used. If you install your own extensions from your master socket, you would use twisted-pair wiring - as is the wiring from the BT junction box (where it enters your property) to your master socket is also twisted pair. Additionally, it's also used in computer networking in offices, hospitals, and other large buildings.

What are the uses of twisted pair cable?
These cables are used in telephone lines to provide voice and data channels.
What are the advantages of using twisted-pair cables?
These cables are used in telephone lines to provide voice and data channels.
Where is shielded twisted pair used?
A shielded twisted pair or STP is a copper telephone cable that secures signal-carrying wires inside a conducting shield. It main purpose is to reduce the possibility of electromagnetic intrusion.
The traditional home telephone cable uses which type of wired transmission cable?
twisted pair
Where is a straight UTP cable used?
UTP stands for 'unshielded twisted pair'. These cables are usually found in Ethernet networks and telephone lines. They are also sometimes found as part of a security network.
How many volts can a landline telephone handle without blowing?
Since the ringer voltage across the twisted pair is 120 VAC RMS the telephone can definitely handle that. Given the fact that the telephone is also supposed to survive induced surges from nearby lightning strikes to the line the telephone should be able to handle over 1000 V common mode impulses (but I don't know the exact limit). No telephone is expected to survive a direct lightning strike to the line (which could be millions of volts). Note: common mode means the voltage is applied between the twisted pair lines (both at about the same voltage) and ground. If the survivable common mode voltage were to be applied across the twisted pair instead it would severely damage the telephone.
What is the speed of twisted pair wiring?
This depends on what "type" of twisted pair. Category 5 ( CAT5 ) cable can transmit up to 100 Mb/s, while Category 6 can transfer up to 1 Gb/s ( 1,024 Mb/s ) The most common twisted pair is CAT5, and CAT5e, used in home networks, business networks, and some multi-line telephone lines.
What are the two most commonly used media types in Ethernet networks today?
1. Copper UTP (Unshielded Twisted Pair) 2. Optical Fiber
What are the advantages of using unshielded twisted pair cable?
One primary advantage of UTP over STP or Fiber is cost. Twisted pair is also more simple to use in many applications (telephone, serial data, etc.) than fiber.
What do you mean by UTP-3?
Unshielded Twisted Pair Category 3. Can be used for 10Mb Ethernet or 2 phone lines, as it has 2 pairs of twisted wired inside.
How data travel in shielded twisted pair?
shielded twisted pair STP and UTP both contain 8 lines inside 4 lines are used for carrying the sending data and 4 others are used for receiving the data this is the reason why collision doesn't occur inside the STP and UTP
What is conventional dial-up?
it is type of Internet connection in which a jack of telephone with twisted pair telephone cabling is used. it is used in making home network and also inexpensive. it is slow 56kpbs
