Provisioning LTPH-UM-1049-02, Issue 2
10 January 9, 2002 H2TU-C-319 List 4E
PROVISIONING
There are two provisioning methods:
Use the MODE and LBK pushbuttons on the front panel of the H2TU-C to:
Set system options
Reset the H2TU-C to its factory default settings for system options
Display system option settings (scroll mode)
Select system loopbacks
Select MTA test mode
Use a maintenance terminal, such as an ASCII terminal or a PC running terminal emulation software,
connected to the H2TU-C craft port or an HMU craft port to access the maintenance screens. Figure3 on
page13 shows the maintenance screen. This provides full access to all H2TU-C status, history, inventory, and
provisioning screens.

USING THE MODE AND LBK PUSHBUTTONS

Setting Options through MODE and LBK

To provision the H2TU-C through the MODE and LBK pushbuttons on the front panel:
1Press the MODE pushbutton for 1 second and then release it. The front panel display alternately shows the
first system parameter and its current setting.
2Press the LBK pushbutton to step through all possible settings of the selected parameter.
3After 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.
4Do 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 LBK pushbutton. A CONF YES message displays,
and the display returns to its normal mode after saving the new changes.
No dip switches or jumpers are required to provision the H2TU-C as it contains a non-volatile
RAM (NVRAM) which stores the system option settings. System option settings are retained if
shelf power is lost or if the H2TU-C is unplugged.
