What Is A DS3?

To meet the ever-expanding need of high-end IP throughput for today's large enterprise, tier-one providers are rapidly expanding their DS-3 footprint, making this carrier-grade Internet connection a viable option for more and more corporate buyers.

A DS-3, also called a T3, is a dedicated circuit delivered by a LEC via traditional local copper networks and, in some cases, over fiber. In its full rate form, a DS-3 has the same capacity of 28 T1s. Like a T1, a DS-3 can be channelized to deliver voice as well as data. When channelized for voice, a DS-3 can hold 672 individual 64 kbps POTs lines. When connected to a tier-one carrier edge router however, it delivers 45 Mbps of bi-directional Internet connectivity.

Who Buys A DS3? …..

Likely buyers of DS-3 service consist of enterprise-size business with high data demands, such as large scale VPN, video conferencing, and corporate-hosted application servers. Software development firms will often require throughput above and beyond the capability of a T1 to handle client upload and download traffic as buyers log onto FTP servers to access patches and newer versions of their product. Hospitals and clinics who share a large number of electronic images such as MRI will require bit rates in excess of the 1544 kbps available on a standard T1. The print industry is a voracious consumer of bandwidth also, as they pass large graphics files to and fro. Local and regional ISPs themselves will use DS-3 circuits as the backbone of their consumer-oriented broadband delivery. Just about any user of tier-one, carrier-grade bandwidth that has outgrown T1 and NxT1 options is a likely candidate for DS-3 service.

What To Consider For DS3 Cost …..

While a DS-3 will always incorporate a full 45 Mbps access Loop, a typical deployment of a DS-3 circuit rarely begins with a full rate Port. Most corporations expanding beyond the limits of their T1 and NxT1 service opt to make the jump to fractional DS-3 such as 6 or 9 Mbps. Often times, a 6 Mbps fractional DS-3 will be more expensive from a monthly recurring cost standpoint than simply bonding more T1s. Corporations who jump from a dual bonded T1 or higher NxT1 speed to a 6 Mbps DS-3 will typically incur a larger monthly price than that of just adding more T1’s. The draw to DS-3 is found in its scalability properties. Upgrades are a matter of resizing the port, which will rarely take more than a few days, and growth to full 45 Mbps can occur at a pace with which the corporation is comfortable. As users scale above 9 Mbps, the DS-3 begins to become the better priced option. Additionally, the cost of CPE required to implement large-scale T1 bonding, along with lowering per megabit prices of the DS-3, begin to sway in the favor of the DS-3.
