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.

Benefits of Dynamic Integrated T1 over Channelized T1

Written by: Dennis Green - Feb 8, 2010

Dynamic integrated T1 provides many benefits over other forms of T1. These advantages include the combination of both phone service, as well as internet service on one T1 circuit for a price which is similar to full internet t1, or a voice t1 circuit. This benefit is especially useful for small to medium sized companies which need both voice and internet t1, but only have the budget for one T1 line. A second benefit of dynamic integrated is that it allows access to all data “channels” at all times, regardless of whether phones are in use or not. With dynamic integrated, the entire T1 (1544 kilobits per second (kbps)) defaults to internet duties. As phones are used, bandwidth is assigned in real-time and with priority to each phone conversation. This prioritization ensures that the quality of voice traffic is not jeopardized by routine data traffic. Once each phone call is ended, the bandwidth allocated to that call is returned in real-time to internet duties, thus increasing the speed of access to and from the internet. Dynamic integrated T1 is the state-of-the-art version of integrated T1. It’s predecessor, channelized t1 was nowhere near as flexible and included much bandwidth wastage. For example, with channelized integrated, each of the 24 channels (64 kbps each) which make up a T1 circuit, is assigned to either voice or internet. I.e. 12 channels assigned as voice lines, and 12 channels (768 kbps) assigned to internet traffic. With this scenario, all data assigned to voice traffic, cannot be accessed for internet usage, without major reconfiguration. For this reason, when phones are not being used, all bandwidth allocated to the phones sits idol. Although dynamic integrated requires on premise equipment worth about $4000, this equipment and installation is provided for only a few hundred dollars by most telecom providers if the customer is willing to commit to a two year contract, and the equipment and installation are usually provided for free if the customer is willing to commit to a three year contract. Other benefits of dynamic integrated often include unlimited local and long distance usage (even in metered areas), up to 5000 minutes of toll free service per month, and online portal access, so that phone features can be accessed and revised in real-time by the customer. Several providers are now offering dynamic integrated t1 on bonded T1 circuits. Also, PRI is now available with dynamic integrated. (Click here to return to top of page)
