| Understanding what a bonded T1 is, and what it | | | | You still have a total of 3Mbits per second |
| brings to the table, is not as complicated as some | | | | bandwidth, however if you have to download one |
| people make it out to be. For T1 bandwidth | | | | file that's 300Mbits in size it will take 200 seconds. |
| specifically, your choices are fractional T1, T1, and | | | | This is because you only have 1.5Mbits per second |
| bonded T1. In other words …. part of a T1, a | | | | bandwidth available as the file cannot be split and |
| full T1 line, or X number of T1s connected to | | | | sent down both T1's at the same time. The other |
| deliver whatever bandwidth capacity you need | | | | T1 is not used for this transfer but is available for |
| met. | | | | other traffic. |
| The benefit of a bonded T1 service is that it | | | | If you had two 300Mbit files to download then it |
| eliminates overtaxing of a single T1. If your | | | | would take 200 seconds to download in either |
| required bandwidth is more than what a full T1 | | | | scenario. |
| delivers …. but less than a DS3 line …. then a | | | | Bonded T1's only help if you transfer large data |
| bonded T1 is a smart choice. | | | | files and time is critical. If time is not an issue and |
| Bonded T1's are basically 2 or more T1's that are | | | | the data transfer is not large then bonded T1's |
| connected to make a fatter pipe. This does | | | | won't help much. In that case stick with a full T1 |

| Lets assume you have 2 T1's bonded together | | | | a point of diminishing return with a bonded T1 |
| ….. | | | | solution. For both capacity and cost. If that is a |
