Drop and Continue Application
In the drop and continue application, up to eight DS1s from one DS3 can be dropped out the
eight DSX-1 ports with the remaining DS1s continuing through to the other DS3 interface (see
Figure 3-2 ). This allows one DS3 worth of bandwidth to deliver DS1s to several sites using one
MX3216 at each site.
