Now, depending upon the CSU/DSU that you have and how the T-1 line is configured (D4 framed or ESF) the USABLE rate might be 1.344 Mb/s, 1.536 Mb/s or 1.544 Mb/s. You also have to worry about the 1's density of the data that you shoving across the line. If you're using inverted HDLC, then you get the guaranteed 1's density that works; otherwise you have to configure your CSU/DSU to insert a 1 bit every so often, thus reducing the amount of usuable bandwidth available to the "user". louie
