NT8D35 Network module
The Network module can be used as a PRI/DTI expansion module. The
number of PRI/DTI expansion modules that can be used is determined by
traffic considerations.
Figure 10 "NT8D35 Network module configured for
PRI/DTI expansion" (page 31) shows the card slot configuration when the
Network module is used for PRI/DTI expansion.
Note: The bus terminating units (BTUs) that are equipped in the
NT8D35AA and NT8D35DC Network module configuration are not
required for, and will interfere with, the PRI/DTI expansion configuration.
The NT8D35BA and NT8D35EA Network modules do not use or need
BTUs for any application.
