What is a high-speed T1 line?
A high-speed T1 is a widely used standard in telecommunications in countries such as North America and Japan. It 'used to send voice and data transmission between devices and appliances. In places outside of North America and Japan, E1, T1 is used instead.
High-speed T1 circuits consists of 24 channels of 8-bits, each channel is composed of 64 kbps. A high-speed T1 circuit is also a full-duplex, meaning that in theory, has the resourcesAbility to send and receive 1.544 Mbps 1.544 Mbps simultaneously.
At the beginning of high-speed T1 actually means "Transmission - Level 1" and that he had with the media that the acquisition has passed the signal. DS1, however, means "Digital Service - Level 1" and this means that the service will initially be digitized voice channels are sent over 24 T1. The terms T1 and high-speed DS1 have become synonymous with each other completely and also includes theAbundance of a variety of services other than voice clear channel data pipes. The best thing about high-speed T1 line is that its always consistent at 1.544 Mbps, but the payload can vary in large quantities.
With a high-speed T1 shows faxes, Internet and telecommunications that is finally over and get moved from the local phone company and, finally, on the long straight away. This type of movement to save on money already in a supportAmount of money over a year. But still it's inevitable that you shoulder the fee in advance, as well as other Internet service providers. Oh, come now I see raised eyebrows, but not annoy you. High-speed T1 can be the workload of your business faster and easier to insure and thus the cost will prove to be equally worthy of an investment.
Today, many companies are often all the high-speed T1 Internet most important to them aloneSupply of 1.544 Mbps connectivity. This is used to 1.536 Mbps allows suitable for traffic during the 8 kbps for framing the head. However, a T1 high-speed version to be ordered as a channeled circuit and the best part is that the use of any number of channels for the data can not be reserved, for example, voice traffic.
Types of high-speed T1
Because of the growing business needs of individual companies have T1 high-speed services for the most important Internet accessbetween small, medium and large enterprises. Due to its rapid availability and reliable, which ensures customers are very sure of his services. High-speed T1 lines are thirty times faster than dial-up connections to the Internet because of its balanced line 1.544 Mbps of upload and download facility.
You can actually find and use high-speed T1, which come in different forms, depending on the needs and requirements of your business. But any high-speed T1Internet service has its price, so you should certain things before jumping into conclusion, the election of high-speed T1 service for your business.
INTEGRATED T1
When it comes to integrated T1, then refers to a similar circuit digital. This only means that if an organization or company has plans with 24 channels at a speed of up to 64 Kbps per channel, high-speed T1 then this can lead to surprising results for your business. AsIn fact, you can experience the freedom to choose how much of those 24 channels must be used for voice calls, and what remains will be used for the data. Thanks to its flexibility in the channels, then it can also called channelized T1.
Fractional T1
Fractional T1 lines are the type of which only a portion of the total bandwidth. It 's almost like having a built-in T1, but the only difference is that the subscriber may use only a fraction of24 channels. Although the method of transmission and data transmission rates remain the same, but the customer only for the number of channels to be used to pay for them. Therefore, already saving a lot of money at the end customer.
T1 BONDED
This type of T1 line is a combination of features as well as the bandwidth of multiple T1 in a single connection. This type of connection may in fact almost the speed of one of the most important condition for the package in a series of activities issingle point of time. To put it simply, this pipeline single higher bandwidth and offer enhanced with outstanding performance.
Burstable T1
A different kind of high-speed T1 line, which can be taken into account is what we call a "pay as you go" service. It 'a very convenient way to pay for the use and increased bandwidth. The price could be very expensive if you use more of his plan of intended use, because you have to pay a premium over the standard planPrices tend to use. However, if your company is fully aware of the traffic patterns of their business, then such a line could also be a good solution.
T1 high-speed work?
In the past, the current frequency division multiplexing transport systems suitable for the connections between distant cities, but requires a complex modulators, demodulators and filters for each voice channel. For compounds within the U-Bahn, Bell Labsin the late 50s trying to look for cheaper mobile phones. The Pulse Code Modulation was once used to allow the exchange of encoding and decoding in a number of voice lines. Since this method has this kind of process T1 elected in their system and took it for local use in 1961. In later decades, the price of digital electronics declined to the point where a codec is used for each voice channel to a common place, but at that time, the benefits and advantagesdigital transmission have already dug in
The shared, the T1 high-speed lines being offered, the line-rate. Now all T1 data circuits running at 1.544 Mbps original. In principle, there are high-speed T1 formatted for 24-pulse-code modulated signals and time management division multiplexing voice, where everyone in a stream of 64 Kbps, 8 Kbps, leaving the framing of information in order to facilitate the synchronization and the code,Demultiplexing at the receiver end. Other types of T-carrier, the T2 and T3 circuit channels that have multiple T1 channels are multiplexed with what you can get around a transmission rate of 44.736 Mbps and 6.312 for the second.
Should be that the rate of 1.544 Mbps according to the test, which is on the AT & T Long Lines in Chicago, the subway were carried out by elected officials. For once the load on the cable manholes were physically coils2000 meters or 6600 meters. In addition, the optimal bit rate was chosen empirically. This means that the capacity has been increased up to the time when the failure rate was unacceptable, then it is reduced to allow for a margin.
Companding permission acceptable to the other side of audio performance, with only seven bits of each PCM sample in the original system of T1/D1. Later, the channel banks are D3 and D4 framing format that allows for each 8-bit extendedChampion, later reduced to 7 for each sample or part of the sixth when he was just "robbed" for signaling the state of the channel. The standard does not allow a sample of all zeros, the binary string of those long and this could cause the repeater to lose that bit synchronization can produce. However, if you wear one of the data is 56, then it may be long strings of zeros. So a little 'bits per sample is at "1" or jam 7 This means that 7 bits are multiplied to 8,000Frames per second for data.
What about the new high-speed T1?
Now imagine what happens if you get a frizz in the garden hose. Thus, the data of the water, while the pressure is the demand for bandwidth. Everyone can flow to reduce the frizz in a drip. In this case, the pressure or the question remains. The data connection is like this water line in a certain way. Although Frizzles has been removed from the network technicians carefully, is the only way too much data in motionTube and when to delete or move data in a faster way for? You must, of course, a tube of grease.
Fatter data pipes are slowly being necessary if the data increases the amount of electronic business, and resolution. An example of this type of file resolution medical imaging, which easily become many megabits and even gigabits cay then for each image.
Now, in a designation laymanized for telecommunications providers, heavy bandwidth starts at T11 544 Mbps in both directions. A high-speed T1 line to send the files that have a few megabytes in a few seconds. Often this can work quite well for text-based specifications and contracts. Low to medium high-resolution photos, CAD files smaller, general accounting and advertising inventory updates in real-time IP surveillance cameras. However, if you like, into multiple files, larger files without having to wait for hours or even a longer period, transferis really a tube of grease, if you want to speed up the transfer.
You can only tree of a T1 pipe adhesive only in the most high-speed T1 lines. If binding of a second line, then you can double the bandwidth of 1.544 to 3 Mbps connection can be up to 10 Mbps or 12 in many places before it can get expensive than the same moves as a tube of grease.
But here's the good news! WAN bandwidth prices have fallen in recent yearsYears and the cost of which is with an update, so the transfer rate which is seriously needed as quickly as possible and probably less expensive than you think to be fair. So go ahead and try to control the amount of investment to go to have thicker tubes. Eventually you will find that it is worth all the effort and investment.
