Dsl, T1, Or Ds3 Bandwidth - What's Right For Your Business?

When would You select Dsl, T1, or Ds3 Bandwidth as the network explication for your firm .... And why/why not? What are the pros and cons for and against each bandwidth type in a firm setting?

In normal .....

High Bandwidth

The answer to these questions is truly linked to your application requirements. If you run applications that are latency or Jitter impacted, then Dsl may not contribute you with the assistance levels you need.

An supplementary prolongation of that would be your requirements for uptime. Mttr (Mean Time to Repair) is typically greatly improved with Ds1 and Ds3 circuits.

The size of the firm is not nearly as prominent as your application requirements. Many large organizations can survive with Dsl or in some cases dial-up, but a small society that has streaming application traffic, mission necessary traffic, or small latency or jitter requirements then Ds1 or greater connectivity would be required.

Lastly, though often primarily, cost helps conclude your choices.

To be more exact ....

T1s and Ds-3s give the same gift except for capacity. T1s give 1.5Mbps upload and download speeds per line. Ds3s give 32-45mbps upload and download speeds.

Adsl typically give asymmetric upload and download speeds (Adsl) typically 1.5, 3.0 and 6.0 Mbps download speeds and somewhere in the middle of 128 -768Mbps upload speeds.

Symmetrical Dsl (Sdsl) gives the same upload and download speeds, typically 384, 512 or 786Mbps upload and download.

Cable offerings vary with providers and location. Doing a comparison with cable would be impossible without knowing your supplier and market. Not who your supplier is and your location .... But knowing how your supplier is in that particular market. Ask a local master for that detail.

T1 and Ds3 are very dependable with high Mtbf (mean time in the middle of failure) and low Mttr (mean time to repair). Cable and Dsl on the other side.

T1 and Ds3 expensive, Cable and Dsl more affordable.

If you do not have a need for high upload speeds, (Vpn, VoIp, high Data replacement for backup/co-location, ftp streaming media or other high bandwidth services hosted in-house, etc) then an asymmetric connection is not evil. Dsl/Cable may be a good selection in that case.

If you need high speed upload then T1/Ds3 is needed.

Fro growing needs, T1 or fractional T3 is a good choice. After some point in growth, a full T3/Ds3 becomes more economical.

For mission necessary networks, two providers from two dissimilar physical points-of-entry may be necessary depending on the natural disasters you are likely to face.

Case study one: a firm had a fractional T3 coming in from the East and someone else fractional T3 coming in from the West. Flooding and a sinkhole cut one T3. The network slowed down but stayed up.

Case study two: a firm in South Florida lost its T1s and failed over to a Satellite link. definite services were crippled by the latency of the law but their mission-critical applications kept running.

Which brings us to Satellite: normally asymmetric with very fast downloads (depending on assistance level) but typically slow uploads (but varies depending on assistance level). Has an intrinsic latency due to the speed of light and the distance of satellites. Advantage: natural disaster resistant, reliable, available in any place and no last-mile issues.

In short...here's the 3 most prominent factors to consider.....

1- Link Speed and Committed Rate

T1 or Ds3 can be purchased as dedicated point to point bandwidth. You will get the advertised speed guaranteed from point a to point b. Key Point if you are purchasing passage to the internet and using the Internet to contribute connectivity (Vpn etc) then you are buying an on-ramp, the traffic on the "highway" after you get on could slow you down. Just because you bought a Ds3 to the Internet doesn't mean that you will have Ds3 passage to all onthe Internet.

2- Link Symmetry

T1 and Ds3 give the same bandwidth in both directions when configured as point to point. dissimilar flavors of Dsl contribute dissimilar up and downlink speeds.

3- Qos

T1 and Ds3 are configurable to preserve Tdm voice (straight out of your Pbx). They can also preserve VoIp. If you are doing all with VoIp it may not matter. If you are retention some Tdm voice it matters a lot.
