FULL DROP AND INSERT OVERVIEW

61200065L1-1
Introduction
The Full Drop and Insert (D & I) option module is one of the
secondary interface option modules available for use with
the ADTRAN TSU 100/600 and provides a second T1
interface.
The D & I module is capable of inserting and extracting data
on a secondary T1 using a DS0 map, the same as is used for
the base TSU 100/600. The D & I should be used in
applications requiring a TSU 100/600 to send data from
different DTE interfaces out two separate T1s. An example is
shown in Figure 1-1. The amount of bandwidth can be
selected.
