T1 VS Cable

What is T1? What is Cable?

Both are great questions for anyone who is making decisions to run a succesful company. What is more effecient and cost effective? Will it be of a higher capacity to let 50+ employees download files at once?

  • CableBroadband Cable Internet (such as Comcast Business Class Internet) uses existing cable lines in or around your office building to bring you Internet access. Cable lines are already present in many areas since companies and residential locations often utilize Cable for television services.

This type of broadband requires a cable modem to be installed at your location, which can either be leased or purchased based on the agreement between you and your provider.

The drawback to Cable is that you share Internet bandwidth with all the other Cable Internet subscribers in your area. If there is a high number of Cable customers in your particular area, the amount of bandwidth available to you decreases, making the connections slower as the system tries to accommodate the needs of each user in the network.

A T1 circuit is a dedicated point-to-point line from your business’ network to the telephone company’s central office and then to the ISP. This fiber optic or copper line can carry data at a rate of approximately 1.5 Mbps.

In addition to a single T1, carriers have the ability to provide customers with bonded T1s. For each T1 in the bond, the speed of the connection increases by 1.5 Mbps. So, for example, if you have two bonded T1s, your connection speed is approximately 3 Mbps. If you have three bonded T1s, the connection travels at 4.5 Mbps, and so on.

A T1 line is often a good fit for a small or medium sized business needing broadband Internet service for twenty to fifty Internet users. The monthly cost of such a line is typically based on distance from the nearest central office, but is generally higher than that of Cable or DSL.

T1 lines are popular with businesses because they provide the same type of “always on” Internet access as other types of broadband but have very few incidences of lost connections since they connect straight to the provider. And, if the service does go down, T1s have a Service Level Agreement (SLA), unlike broadband. With an SLA, there’s a guarantee of performance, a latency guarantee, and a guaranteed time to repair if the service goes down.
