With all the options now ... such as Ethernet, wireless, etc ... Bandwidth T1 (and all its variants), also a decision that sound like a network solution (or part thereof) for businesses today?
Although the T1 is a power through a technological universe from a galaxy far away. It is still widespread and customers both large and small orders. This is a very large base of private IP networks, the trip on T1 circuits. But if we just be, we should call DS-1because what we're really talking about the telephone network signaling format used and still be valid.
I believe that the telephone network is severely undervalued and understood by most network engineers. We have and will continue to build for a long time, logical networks on the back of the phone with the physical network. Major airlines have gradually built networks of large data packet in parallel with the public telephone network, but the existing networks are still dependent on network infrastructure for telephonyAccess.
The central question is what other high speed services are available and at what cost. Significantly higher service speed can even cost less than a T-1. With the advent of Pseudowire technology enables a basic package of services and still derive TDM interfaces such as T-1, T-3, etc., with all the schedule, functionality and QoS of the services of traditional carriers. The fact that many of these new services, packet-based (IP, Ethernet, MPLS), it means that you can keep your existing phoneor need other equipment, a T-1 circuit, and the transition to VoIP or a package of other applications based on the latest. Having done that, still a great bandwidth is left for access to the Internet, video, VoIP, etc.
From the Network Service Provider (NSP) would be seen love, that transport TDM traffic to their customers on their higher speed IP / MPLS backbone networks. Many of these NSP continues to be the older TDM (SONET, ATM, Frame Relay, etc.), networks, because their customerswant to change. That said, which could lead to the same benefits through the use of modern gateway products, and get the benefits of assisting customers with a simple Layer 2 network.
Note that a T1/DS1 is just a pipe. If his works B8ZS configured to 1.54 Mb in front of the head, with its 1.34 AMI - you lose the bandwidth, thanks to the design and protocol overhead. Its 24 DS0 can run either on 64 or 56 kb.
You can run any type of traffic on it, ATM. MPLS. HDLC. Frame Relay, Voice (youAdd rule to echo B8ZS can voice), VoIP ...
No matter whether it is viable depends on what you need, what kind of local network or input devices to support the site, how many ends you purchase available, the suppliers if they are local or national, reliability, enterprise applications ( eg load different media, conferences, etc.), and some other considerations ....
A T1 is still a viable option for small businesses. The Telco can be created and PRIControl / split the channels so that sufficient space for a meg of data and the use of telephone lines enough for the company.
Most suppliers of Telco waived the installation charge and give you a deal on another device to be installed, they need to bring your data and operation. At this point, the small company to a local technology has found their firewall configured to access, and are in operation if their phone is available.
Put in some "new" areas, no fibers were,that the telephone company is not billed for the sharing of T with a PRI, so it is possible with DSL (blocked unless you do not want to pay for multiple analog connections and a separate T1, run the bill over $ 1000 / month). DSL bandwidth is good for speed and offers many, but a T1 is much more reliable than DSL in most plants. DSL is also more difficult to an internal mail server is always a static IP, DNS records, blacklists constant DSL users to switch displaynauseum.
A T-1 implies a much higher cost per megabit then other means less expensive. It comes with the extra cost, although some specific advantages. A T-1 helps to ensure availability. This means that the circuit is monitored 24 / 7 for the problems, and most airlines guarantee your Internet or point to point will be functional and 99.99% of the time. That is, for example, if your company hosts its own mail server and e-mail delivery of mission-critical.
In addition, a T-1comes with "Quality of Service (QoS). In short, make sure that everything will send QOS in the same order in which they handled skillfully. This is for the companies offering Voice over Internet Protocol (VoIP) or undertaking a VOIP / Pri Phone attractive to use the system. It ensures that your data entry that speaks more smooth and minimizes the delay between you, and if the other party feels.
DSL is usually a cheaper solution, and usually offers a higher bandwidth for each circuit forsmaller companies. But beyond the lack of reliable SLA, DSL lines do not have the definitive troubleshooting and fault detection systems that are integrated into T1 circuits and related hardware.
In short, the demand for applications that require flexibility, T1s remain a safe bet on their own or combined in multi-circuit connection.
If your company only have access to the Internet should be, and none of the above situations applies to you, chances are it's business DSLgo to a cheaper and faster way for your company.
Always remember not to do ..... Your WAN or Internet connection should be determined by your needs, and not an opinion that technology T1 is old, or a personal preference for an alternative. Until or your company responds to some questions regarding your intended use, it makes little sense to say that among the various possibilities of this. Networking is not a "one size fits all world."
All in all,T1s but are here to use in order to stay for a while ', at least for small businesses. Users T1, is not declining in number, but the T1 lines are installed easily record and a lower percentage of market share, because the number of companies have a total whatnot, connectivity and availability of fiber / cable /.
The bottom line is that T1s certainly a viable option for some. With the equipment already in the network the most part, the costs of distribution are not very nice to non-existent. If the device is not inPlace would probably cost effective for the development of new technologies such as Ethernet or FTTP (Fiber to the premise).
Again, T1 Bandwidth is here to stay. Why? Since the T1 always some form of business model.
