DSL, T1 and T3, Fiber-Optic What Does All That Mean?

dedicated T1 and T3

Your business will want the fasted internet speeds with reliability, right?

For your business you may not be as concerned about these different technology terms, but you will be concerned about what you are getting for the money.

DSL Internet

DSL or digital subscriber line is a high-speed internet connection that uses a regular business telephone line.  No new wiring or connections must be put in place since telephone lines can be utilized for both the business phone and business internet.  DSL is better for receiving data over the internet than it is when sending data so that may be something to consider if your business wants low cost business internet.  AT&T offers DSL at competitive rates since many customers have moved to faster cable internet service providers like Comcast business.  If your business is in an area or office that Charter or Comcast does not service you may consider DSL from AT&T vs Comcast.  Costs can be as little as $15 per month for speeds up to 1.5 Mbps and $20 for 6 Mbps speeds.  Verizon DSL has a similar cost structure and availability is widespread.

 T1 and T3 Lines

T1 and T3 lines are leased connections that are rented usually monthly to connect two or more separate company locations for internet service and networking as well as phone service.  They are operated over either copper or fiber optic cables.  T3 lines are a group of 28 T1 circuits that are bundled to produce around 44 Mbps of total bandwidth.  Sometimes companies use T3 lines at their headquarters to build their network infrastructure.  As mentioned earlier, these circuits are reserved or dedicated circuits and costs start around $500 per month.  Bundles of T3 lines can cost above $2,000 per month to lease.

Fiber simply refers to fiber-optic cables that are used to send signal for both data and voice.
