One Exchange Office Management Unit (EMU) can manage up to 32 HDSL
circuits, where each circuit consists of one LTU and one NTU. When one
managed shelf is used, and the number of deployed LTUs exceeds the
capacity of the 20-slot shelf, the excess LTUs can be installed in single-slot
enclosures connected to the managed shelf. The excess LTUs must then be
set for an “external address” that ranges from 21 to 32.
The location of the DIP switch used to set LTU addresses is shown in
Figure 2 . The LTU address DIP switch settings are listed in Table 4 on page 9 .

Wear an antistatic wrist band connected to earth ground
when installing these units. Avoid unnecessary contact with
board-mounted components.
LTUs installed in a managed shelf do not require address
settings.
