Understanding What a T1 Line Can Do to Your Business

What is a T1 line?T1 lines are those specific types of copper or fiber optic telephone lines that can handle more data and files in comparison to the traditional and conventional telephone lines. Commonly known as the T-carrier lines, it was developed by the telecommunication’s company AT&T Bell Labs for usage in countries such as North America and Japan.These twisted copper telephone lines have been used as the standard line or connection for quite a long time now. Back then, it was already used for the transmission of voice and data through analog signals. As of today, this standard is slowly upgrading to fiber optic lines that are made up of bundled glass fibers, however, most T1 lines are still made of twisted copper. T1 lines have the capacity of creating pipes which are capable of blowing through larger data streams.Now, while other people are having a grand time having a trip to their favorite local shopping mall, shopping for telecommunication services like that of a T1 line can also be fun and worthwhile. Now if you are looking for a dedicated voice line, you have the freedom of calling the local phone company. However, chances are, you will be passed around three to four personnel but still don’t have any idea or they cannot handle your request for T1 line. By the time you get to speak to the person who knows about the T1 line, you still have to suffer in going through a long litany of questions that still don’t get to the point of your call which is actually how much do you have to pay to enjoy a T1 internet line.So, the cost of having a T1 line can be very expensive. But you have to know that prices are dropping as long as the demand and the trend grow. Internet Service Providers or the ISPs can lease T1 lines to provide services that are needed to their network of clients. There are also other multiplexed fiber optic lines such as T2 and T3 lines which has the capacity of transferring up to 44.436 Mbps. Having a T3 line is even equivalent to 28 T1 lines and is being utilized by larger establishments that have higher data and voice demands – but that is another story. More other advanced T-carriers also exist although they are not highly used.But generally speaking, having a T1 internet line is not a wise decision and not cost effective for personal or residential use. Small businesses and other organizations that are using PBX are the ones that can greatly benefit from having a T1 line.Types of T1 lineA T1 line is a kind of circuit that is used for voice or data traffic transmission at a speed rate of 1.544 Mbps which is equivalent to 1,544,000 bits per second. The reliability and dependability of having a T1 line is way greater in comparison to that of a standard telephone line or DSL. Telecommunication companies tend to give higher service level agreements or SLA to T1 lines unlike the common DSL or telephone line. Almost all T1s come with SLAs that will give the customers an assurance and security when it comes to things such as speed, uptime as well as latency or the time that it takes for the signal to travel from one point to another. Digital pipelines or carriers are also available in many different sizes which have the capacity of supplying any data delivery equipment virtually.Here are the types of T1 lines that you can choose from:VOICE T1: it has the ability of handling up to 24 calls concurrently, even more when the device has a voice compression. This means that it compresses the standard 64 Kbps bandwidth for every call to as low as 8 Kbps. There are also no limits into how many telephone numbers that can point to a T1 which permits some other companies to have hundreds of numbers pointing a single T1, which are referred to as Direct Inward Dialing or DID numbers.CHANNELIZED T1: it is a T1 line that is being split up into 24 equally divided channels. Each and every channel that is referred to a DSO or Digital Signal, level zero that can transmit 64 Kbps. This type of line can be directly plugged into a PBX for a phone service usage. These T1s also have no features since all its special features are being provided by the PBX itself.ISDN PRI: ISDN PRI stands for Integrated Service Digital Network – Primary Rate Interface which is another type of T1. The main difference between a normal T1 and a PRI is that PRIs use one of the 24 channels that are available into a T1 as the data channel. This channel can handle the customer call information as well as control signals instead of the actual call. The features of an ISDN PRI would include Caller ID and screen pops, customer information and history that pop up on the computer screen when there is an incoming call being answered.Other types of T1 that you can also choose from are the DATA T1, PRIVATE LINE, FRACTIONAL T1, INTEGRATED T1, DYNAMIC T1 and BONDED T1.How does a T1 line work?Lo and behold the latest technology that an internet service provider has to offer, that is T1. T1 lines are those copper or fiber optic lines that have the capacity of carrying data than the traditional phone lines. As I have mentioned in my previous posts, T1 lines were developed by the AT&T Bell Labs for the usage of certain countries such as North America and Korea.But what is a T1 line exactly? How does it work? Well, T1 lines actually define four things: the bandwidth or clock rate, the physical medium that are being used, the type of signaling and encoding that are being used and lastly, the format or frame where data are being sent or transferred.To start off, T1 lines have a speed bandwidth of 1.544 Mbps for one direction, alone. One of its biggest advantages is that owning a T1 line can give you a truly dedicated bandwidth for both the uplink and downlink directions in a symmetrical manner. T1 lines by the way are not shared with other customers which makes it possible for a high speed rate.Two physical mediums are being utilized by a T1 line. The first medium that is being used is based on a 100 Ohm which is in a form of twisted and shielded differential pair. The second medium, on the other hand, is based on a 75 Ohm coaxial cable. Usually, inside the patch panels of a 100 Ohm twisted pair is oftentimes being used because it is not expensive and it is also flexible. When being utilized for sending data to the outside world, however, a balun is usually used so that it can match up with that of a 75 Ohm coaxial cable which is normally used in connecting to ISPs or PBX.B8ZS which stands for Binary 8-zero Substitution is the signal encoding device that is used by T1 lines. To avoid being too technical about it, it can just be simply described as a type of encoding which allows the data and the clock to be sent to the same T1 cable which is very crucial in order to have a synchronized data transfer.Finally, the format in which each T1 line is split into 24 channels is referred to as the DSOs. Each of the channels is 8 bits wide and the frame is being sent into a boundary of 8 KHZ. Hence, making the data capacity of 1.536 Mbps which is derived from the multiplication of the channels, 24x8x8000. Meanwhile, there is also this something called as the framing but which consists of 1 bit for every frame that has the capacity to be locked on the other end so that there is an assurance that whatever device there is, it can extract DSOs in a correct manner. 8,000 bits per second, once again is being added in this framing bit, which results to a grand total of 1.544 Mbps.Latest Updates on T1 linesKnowing about how T1 lines work can actually help you in deciding whether your company is going to avail of these lines or not. And while you are still contemplating on whether you are going to get that T1 line from your provider, here are some of the most incredible things as well as features that you can simply anticipate and expect for all those T1 and internet business enthusiasts. Now, aside from getting the advantage of having a program which is faster and speedier, it can also transmit and send voice and data with a rate of as much as 1.544 Mbps. But these facts are already served in a golden platter. Lets hold our breathes together as I unfold to you some of the latest developments from your favorite internet connection.Combined T1 Telephone and Internet Service: this development just means that an Integrated T1 line will be sharing bandwidth between digital phone lines and broadband internet service. Normally, there will be up to 12 phone lines that can be accommodated. For instance, if a T1 line that is set up is a dynamic or an active one, then any bandwidth that is not used for telephone calls can be automatically available for Internet access.Digital Signage Bandwidth Options: another development in which it concerns on the digital signs like those large billboards that can be easily and instantly updated through the use of data download. T1 and Fractional T1 lines or VSAT digital satellite connections are available even on rural areas.Pseudowires: this is actually some kind of a virtual “circuit” that can imitate a traditional or conventional digital telecom service. However, only on a packet switched network is suitable with MPLS networks. With the use of pseudowire circuits, your company can avail of the point to point connectivity that you like and want without having to re-engineer your facilities just to fit a different protocol network.WISP or the Wireless Internet Service Provider: this feature, on the other hand, makes its way to connect the Internet to tower radios and bonded T1s are the ones that are being used mostly for this purpose.A digital telephone trunking: T-carriers such as T1 offer that can carry multiple phone calls on one physical circuit.Knowing and seeing the developments mentioned above, it would not be a surprise anymore that the usage of T1 as the main internet connection will not just be confined into World Wide Web usage. As the time progresses, more and more things could possibly happen by just merely using the T1internet line as your company’s main service connection.
