ADC H4TU-C-319 List 1 Line Unit Manuel D’Utilisation

There are two methods for provisioning: 

Use the MODE and SEL pushbuttons on the front panel of the H4TU-C to:

Set system options

Reset the H4TU-C to its factory default settings for system options

Display system option settings (scroll mode)

Select system loopbacks

Use a maintenance terminal (ASCII terminal or a PC running terminal emulation software) connected to the 
H4TU-C craft port (or to an HMU craft port) to access the maintenance screens (

). This 

gives you full access to all H4TU-C status, history, inventory, and provisioning screens.

To provision the H4TU-C-319 through the MODE and SEL pushbuttons on the front panel:

Press the MODE pushbutton for 1 second and then release it. The front-panel display alternately shows the 
first system parameter and its current setting. 

Press the SEL pushbutton to step through all possible settings of the selected parameter. (See 

 and 

.)

After the desired setting has been selected, press the MODE pushbutton. This updates the current displayed 
parameter to the selected setting, then advances to the next configurable parameter. After the last parameter 
has been selected, a 

CONF NO

 message appears on the front-panel display.

Do one of the following:

To cancel the session without saving the requested parameter changes, press the MODE pushbutton or 
do nothing. (After 30 seconds, the display returns to its normal mode without saving the new changes.)

To accept the requested parameter changes, press the SEL pushbutton. (A 

CONF

 

YES

 message appears, 

and the display returns to its normal mode after saving the new changes.)
