Drop and Continue Application
The following applies to Remote Site #1 shown in Figure 3-2 . In the Drop and Continue Appli-
cation, any combination of DS0s from one DS1 can be dropped out the other DS1 ports with
the remaining DS0s continuing through to the other DS1 interface. This enables the
bandwidth of one DS1 to deliver DS0s to several sites using one MX410 at each site.
