MX410/MX412 System Manual Drop and Insert Application
61189500L1-1B PRELIMINARY 3-7
Drop and Insert Application
The following applies to Remote Site #1 shown in Figure 3-7. In the Drop and Insert Appli-
cation DS0s from one DS1 can be dropped out to the other DS1 ports. Then, DS0s from the
other DS1 ports can be inserted into the corresponding DS0s in the other DS1. In the example
shown, any DS0 not dropped will be mapped to continue on from one DS1 to another. This
allows a DS1 to be used to transport DS0s between several sites.
