DS3 Works for Large Volume Internet Transfers

DS3 FOR LARGE VOLUME DATA AND VOICE TRANSFERS

It is becoming obvious that a standard T1 circuit will not be able to cope with the growth of bandwidth applications. For example a T1 circuit is 1.5 megabits/sec whereby downloading a three minute piece of music is 3MB or 24 megabits.

Uploading or downloading a digital photograph would use 2 MB or 16 megabits. A Power Point presentation is 10 MB or 80 megabits. If several office workers were to transmit a Power Point presentation at the same time the T1 connection would slow down for three or more minutes.
