DS3 providers are the telecom companies which provide DS3 circuits to end users. DS3 is a 45 mbps (megabits per second) circuit. A DS3, commonly referred to as T3, is the equivalent of 28 DS1s (commonly known as T1s). (For more about DS3 providers, please click here)

Unlike DSL and other broadband technologies that are limited to only densely populated areas, T1 service is available just about anywhere with a phone line. T1, also known as DS1, uses repeaters to boost up the signal strength of the transmission - allowing it to travel up to 50 miles away from the nearest Central Office location. Our coverage area includes all of the following states:

DS3 Providers Continued.

DS3 is commonly used by large companies which need: point-to-point (private line) circuits, MPLS (multiprotocol label switching) VPNs (Virtual Private Networks), voice (telephone), internet traffic, VoIP call centers, video conferencing and broadcast quality video transmission. Alternatives to, or variations of DS3 include: DS1, bonded DS1, fractional DS3, burstable DS3, voice DS3, data internet DS3, integrated DS3 and OC3. Each of these variations has advantages over the others, depending on the specific needs of your company. Also, the availability of each is based on the offerings and geographic proximity of each DS3 provider. Every DS3 provider has different specialties related to geographic specialization and the services they offer. A provider is considered tier 1 if they are also the carrier, the owner of the facilities they offer. DS3 providers are considered tier 2 if they are the direct reseller of the services of one or more carriers. A provider who resells the services offered by tier 2 DS3 providers is considered tier 3. Often, the services of tier 2 providers are less expensive than those offered by a tier 1 provider. However, whenever a customer can purchase directly from the tier 1 provider for a price that is similar or better than offered by a tier 2, it’s generally better to go with the tier one. This is because as the carrier (owner of the facilities), the tier 1 provider has direct access to all of their facilities. Although, almost all tier two providers offer service level agreements (SLAs) to guarantee service levels, there is only so much they can do, if they do not have direct access to the facilities they are reselling. This becomes especially important during installation, maintenance, and emergency outage situations. In these situations the tier two must coordinate with the tier one to resolve issues. As a general rule, the more entities that are involved, the greater are the coordination issues which can arise. Excessive coordination issues can result in down time for the end user. In many cases, down time equates to lost services and/or lost revenues. Tier 1 providers can commonly provide most forms of bandwidth, including most of the DS3 related services listed above. Usually, tier 2 providers are more specialized in their offerings (less variety), depending on their underlying contracts with the tier one providers.

MPLS Facilitates Convergence

Written by: Dennis Green - Aug 20, 2008

With the emergence of multiprotocol-label-switching (MPLS), great strides have been achieved toward the goal of telecom convergence. In the past, telecom applications such as voice, internet, networking, and video conferencing have been treated as separate, commonly each needing their own source of bandwidth. This was expensive, because it is often far more costly to provide several relatively small bandwidth pipes, then it would be to provide one large pipe. Generally speaking, the larger the pipe, the less cost per megabit per second (mbps). Other issues which were frequent with a lack of convergence were that it was common for providers to specialize in one application, but not all. For this reason, it was required for businesses to be forced to deal with multiple providers, to obtain multiple types of service. Also, the business (customer) would need staff who could specialize in each application. For example, staff that specialized in coordinating the company phone system, staff that specialized in setting up internet access, and staff who specialized in setting up wide area and local networks (WANs and LANs). With a lack of convergence, capital costs were much higher as well. I.e., separate routers for connections to the WAN and LAN, separate routers for the internet, and separate equipment for connecting to the public switched telephone network.

With convergence, this is all improving for the business owner. Now, it is possible to obtain a completely managed system, which includes voice, internet, free long distance service, free toll free service, and soon to come, networking all on one bandwidth pipe, provided by one provider. This results in less expense for bandwidth, fewer company staff resources required to manage, and less expense for each application. With the emergence of dynamically allocated bandwidth, far greater efficiency is being achieved in bandwidth utilization as well. For example, not only can you have both voice and internet on the same T1, but you can now utilize all bandwidth for internet, when the phones are not in use.

At this point, MPLS is most affecting the convergence of communication within the communication network of each company. With MPLS, companies can now converge all applications, such as company location-to-location voice, routine data transfer, and video conferencing into one network. All can be transferred over one pipe, with any-to-any connectivity. With MPLS, class of service (CoS) prioritizes these applications so that those which are more sensitive to packet loss and latency receive priority over applications such as routine data transfer. For example, routine data transfer would not be allowed to compete directly with voice traffic. Routine data traffic is not sensitive to minor packet loss or latency, and therefore would be given a lower priority than voice or video traffic.

Converting from an out-dated frame relay or point-to-point network to a fully managed MPLS based network is an extremely painless process. In most cases, all installation is free, equipment and configuration is managed by the telecom provider, and the telecom provider takes full responsibility for monitoring the network 24 hours a day, seven days a week, and providing all maintenance for the network. All of this is usually provided for far less than the monthly cost of the existing network.
