Enter selection or <Esc> to go back to main menu

loopback state as well as the configuration of transmission pa-
rameters and options in the loopback path. Figure 20 shows the
NIU in a single loopback mode when FAC-to-CPE Regenera-
tion is Enabled.

9.2.4.7

Using the <Ctrl><D> keys simultaneously will cause

the NIU to deactivate loopback and return the circuit to normal
operation.

9.2.5

TEST MODE PROVISIONING Menu Screen

The TEST MODE PROVISIONING screen (Figure 21) is used
to configure the unit’s options for the test mode. To reach this
screen from the MAIN menu, type <S> to get into the STATUS

Screen and then type <T>. For each option, the display shows
the CURRENT" configuration as well as a NEW" field that
shows what the option can be changed to. Use <tab> or the ar-
row keys to advance to an option field. Use the <space> bar to
change the available options under the NEW" field.

9.2.5.1

Saving The Changed Options

After configuring the options, press <S> to save the new set-
tings. 

Note: 

If you enter <Esc> without saving, the system will give

a message asking if you want to save the new settings.

- WARNING -

If the craft terminal is disconnected without saving the changes, the
changes will be lost (unit does not save changes automatically).
