100R INA and 100 DCD Modules
New Programming Options 4
The 100R INA and 100 DCD modules use many of the same programming 
options as the 100 DS1 module. However, the 100R INA module has two new 
programming options: Activate/Deactivate the On-Board CSU and Channel 
Selection. The 100 DCD module has the same programming options, plus two 
additional ones: Activate/Deactivate the DSU and Programming Data Port 
Parameters. Along with these new options, this section also covers some 
preexisting options which have changed because of the 100R INA and 100 
DCD modules. 
Activate/Deactivate the CSU 4
The built-in CSU is factory-set as activated on the 100R INA module and 
factory-set as deactivated on the 100 DCD module. It can be reached by using 
the following sequence:

Line and trunk administration for the 100R INA and 100 DCD modules 
is the same as the 100 DS1 module. Each 100R INA module’s line 
and trunk settings must be configured for T1 or PRI before it can be 
used by the system and/or router. The 100R INA and 100 DCD 
modules are set to T1 by default. 
Changing the CSU setting may affect voice calls. The system 
waits until it is idle before activating or deactivating the CSU.
