In the Drop and Insert Appli-cation DS0s from one DS1 can be dropped out to the other DS1 ports. Then, DS0s from theother DS1 ports can be inserted into the corresponding DS0s in the other DS1. In the exampleshown, any DS0 not dropped will be mapped to continue on from one DS1 to another. Thisallows a DS1 to be used to transport DS0s between several sites.Figure 3-7.
