DS3 for Large Office Bandwidth Needs

Small and midsize businesses (SMBs) with more than 50 employees are likely to suffer limitations with a single T1 line. If the company needs just a little more, two T1s may be an adequate solution, but for companies that expect more growth or have substantially more employees, a DS3 line may provide a better option.

DS3 and T3, What’s the Difference?

The terms DS3 and T3 are used interchangeably, and there is no difference between the two. A DS3 line is actually made up of 28 T1 lines, and it delivers a total bandwidth of 45Mbps. Each T1 has speed of approximately 1.5Mbps.

The T3 line, like the T1, is symmetrical. This means that upstream and downstream bandwidth is the same, which is often important in a business environment. Ordinary home broadband typically carries greater bandwidth coming in than going out, which suits most home users. However, businesses that may be using web conferencing, hosting their own web servers, or otherwise pushing content out to a large audience will require a symmetrical system that affords the same bandwidth in both directions.

Moving from T1 to DS3

Users of T1 lines understand that if their office is small, a full T1 is not needed, and a fractional T1 may fit the bill. Similarly, growth may require multiple T1s together. DS3 works the same way. When joining together multiple T1s still does not meet demand, there will be a point at which it is more affordable to obtain a DS3 line instead. In general, though a DS3 is equivalent to 28 T1s, the price of the DS3 is substantially less than paying for 28 T1s individually, and so when purchasing bandwidth, it is important to calculate your break-even point at which it is better to upgrade to the DS3, even if it means you are buying more bandwidth than you need. Another option is a fractional DS3 line.

DS3 Options

There are multiple options to consider. In addition to the fractional DS3 line mentioned above, a burstable DS3 is suitable for those who will have an average bandwidth need of less than the available 45Mbps, but may encounter peak periods where bandwidth needs actually come closer to the full amount available. This option is less costly than a full, traditional DS3, since most of the time you are not using the full available bandwidth. Usually, instead of paying the full cost of a DS3, you pay a lower cost, with an additional fee levied for periods during which your bandwidth hits peak periods.

Your carrier will typically provide a Service Level Agreement (SLA) with your DS3 service, which will include service guarantees regarding both uptime and quality of service.

How Much Will It Cost?

The cost for your DS3 will vary depending on your carrier, and your proximity to the carrier’s network. DS3 typically is charged based on two factors: the local loop, and a port charge. The local loop charge depends on the distance between your physical location, and the carrier network (the “last mile”). Because of the proximity factor, what may be the most affordable carrier for one company may not be the same for another.
