Fractional T1 Lines

It is possible to purchase T1 lines which only partially utilize the maximum transfer rate of 1.54 Mbps. These are referred to commonly as “fractional T1 lines”. This allows for T1 service that is more affordable when all 24 channels are not necessary.

Fractional T1 lines are exactly the same as Full T1 lines, except the only the difference is the amount of separate 64Kbps lines provided. These T1 lines are available in nearly any fraction of the full 24 channel circuit. For example, a 12 channel fractional T1 line will provide 12 lines of 64 Kbps bandwidth, or 768Kbps (12 x 64 = 768). Since full T1 lines have become more affordable recently, fractional T1 lines are not as cost-effective as they once were.
