Drop and Insert Application
In the drop and insert application (see Figure 3-6), DS1s from one DS3 can be dropped out the
DSX-1 ports. Then, DS1s from the other DSX-1 ports can be inserted into the corresponding
DS1s in the other DS3. Any DS1s not dropped continue on from one DS3 to the other. This
application allows a DS3 to be used to transport DS1s between several sites.
