T1, Fractional T1 or NxT1
When discussing a T1, we also have to look at the variations of the T1. It can be a Full T1 or a Fractional T1.
A T1 can also be bonded to more T1's to effectively double the speed.
We refer to this as NxT1. Here are a few examples:
NxT1 connects 2, 3 or 4 dedicated T1 circuits.
The speed then would be 3 Mbps, 4.5 Mbps or 6 Mbps, respectively.
When you get a price on this T1 service you should also ask if you pay for the local loop or is it included in the price from your bandwidth service provider. A POTS line or (plain old telephone) line will not carry this signal.
This service typically has a guaranteed up time and is more reliable than DSL.
Note: 1500Kbps is the same as 1.5Mbps
