With all the options currently available ... such as Ethernet, wireless, etc ... T1 bandwidth (and all its flavors) even a viable choice as a network solution (or part of one) for today's society?
While the T1 is a handle on technology from a universe of a distant galaxy. E 'is still widely used and ordered by customers big and small. There is a very broad base of private IP networks running on T1 circuits. But if I'm correct, we refer to it as DS-1because what we really talking about the size of telephony signaling still in use and vital.
In my opinion, the telephone network is severely underestimated and understood by most network engineers. We will for a long time and are logical networks built on the back of the physical telephone network. Major airlines have gradually built up large networks packet data in parallel with the PSTN, but these networks are still dependent on network infrastructure, telephonyaccess.
The key question is what other high speed services available, and at what cost. Much higher speed services can cost less than a T-1. With the advent of Pseudo-Wire technology, you can use a package of basic services and draw more TDM interfaces such as T-1, T-3, etc., all the timing features and QoS services of traditional carriers. The fact that many of these new services are packet-based (IP, Ethernet, MPLS), you can use your existing PBXor other equipment that needs to track T-1 and the transition to VoIP or other packet-based applications later. Without this, you still have a considerable bandwidth left over for Internet access, video, VoIP, etc.
The Network Service Provider (NSP) perspective, they want their customer TDM traffic to be transported to their higher speed IP-MPLS backbone networks. Many of these NSP, older TDM (SONET, ATM, Frame Relay, etc.) networks run because their customers do notwant to change. That said, they could provide their services by using modern gateway products, and get the benefit of supporting customers with a single layer 2 network.
Remember that a T1/DS1 is just a pipe. When configured for B8ZS 1.54 MB running on air with AMI 1.34 - is lost due to framing overhead bandwidth and protocol. His 24 runs on 64 DS0 or 56 kb.
You can use any kind of traffic, ATM. MPLS. HDLC. Frame Relay, Voice (youEcho can usually do with B8ZS for voice), VoIP ...
If it is advantageous depends on what you need, what kind of input or loop structures are available on the site that you support, what you end up buying, or your local or national providers, reliability, enterprise applications (eg Load multi-purpose media, conferences, etc.), and some other considerations ....
The T1 is still a viable option for small businesses. The Telco can place and a PRIcontrol and division of the channels, leaving enough room for a meg of data and adequate telephone lines for business to operate.
Most providers will give telco for the position of installation and give you a deal on all the equipment needed to install your data to work. At this point, the small company is looking for a local technician to configure your firewall to access and are up and running if their phone system is in place.
Some "new" areas, no fiber was placed,The Telco is not a price for the division of a T with a PRI, then you're stuck with DSL (unless you want to pay for a separate analog lines and T1, the bill runs over $ 1000 per month). DSL is good for the bandwidth and offers a lot of speed, but a T1 is much more reliable than DSL in most installations. The DSL also requires an increased effort in internal mail server is managed to obtain a static IP, DNS records, constant blacklisting of DSL users, ad nauseam.
A T-1 provides a significanthigher cost per megabit average less expensive than others. The additional costs will be a series of specific advantages. A T-1 plays an uptime guarantee. What this means is your circuit is monitored 24 / 7 for the problems, and most of the carriers to ensure that your Internet or point to point will be functional and 99.99% of the time. This is important if for example your company hosts its own mail server and delivery of e-mail is mission critical.
In addition, a T-1 is equipped with "Quality of Service (QoS). In aIn short, QOS makes sure that everything you submit is processed in the same order has been sent. This is interesting for companies that use Voice over Internet Protocol (VoIP) or a company / PRI VOIP phone system. Make sure that your voice comes across smooth data and minimizes the delay between the time to talk to and when you hear the other party.
DSL is usually a cheaper solution, and usually provides a higher bandwidth-per-chip for small businesses. However, despite the lack ofSLA reliable DSL circuits also a lack of problem solving and more definitive identification error in T1 systems, integrated circuits and related hardware.
In short, for applications that require resilience, T1 is a safe bet on their own, or combined into circuits Multilink.
If your company only needs access to the Internet, and none of the above scenarios apply to you, business opportunities DSL is cheaper, faster option for yourcompany.
Again this in mind ..... WAN or Internet connection should be determined by your needs, not an opinion that T1 is an old technology or a personal preference for an alternative. Until you or your business is responding to questions about the intended use, it makes little sense to say what is feasible from the different options available. Networking is not a global "one size fits all".
Overall, however, T1 are here to stay for a while 'at leastfor small businesses. T1 users can not be reduced in number, but the installation of T1 are only capturing a market share due to the smaller number of companies that need global connectivity and the availability of fiber / cable / whatnot.
The bottom line is that T1 is certainly a viable option for some. With equipment already in most networks, the distribution costs are virtually nonexistent. If the equipment is in place, it would probably beconvenient to implement new technologies such as Ethernet or FTTP (fiber to the premise).
Again, the bandwidth of T1 is definitely here to stay. Why? As the T1 will always be part of a unique business model.
