Setting System Options.
To initiate the Option Setting mode:
1
Press the Mode Setup button for two seconds and then release.
The message displayed on the front panel alternates between the first system parameter and its
current setting.
2
Press and release the Choice Setup button to display all possible parameter settings (one at a
time).
3
After the desired setting has been selected, press the Mode Setup button
This updates the current displayed mode to the selected setting, then scrolls to the next
configurable parameter. After the last parameter has been selected, the display shows:
CONF NO
4
Do one of the following:
If you do not want to change any of the parameters, press the Mode Setup button.
If you want to accept the changed parameters, press the Choice Setup button.
A YES message displays and the selected changes are installed.
In either case the display returns to its normal mode.
The display also returns to its normal mode, without installing any new changes, if
neither button is pressed for 30 seconds.
12.3
Setting Options to Factory Default Values.
Table 9 also shows the factory default values for
the system options. To set the options to the factory default values:
1
Press the Choice Setup button for six seconds until the following message appears:
DFLT NO
2
Do one of the following:
To set the default values press the Choice Setup button while the DFLT NO message is
displayed. The following message then appears indicating that the factory default values are
now in effect:
DFLT YES
To terminate the DFLT mode without setting the factory default values, press the Mode
Setup button or do nothing for 30 seconds. The latter returns the display to its normal state.
12.4
System Inventory.
To view a system inventory:
1
Press the Mode Setup button for three or more seconds.
This causes the display to scroll through the software version number, its List #, the received
frame type, the received line code type, and all option settings. The line code parameter is the
actual DS1 line code being received by the HLU-D41 if the DS1 code pattern is set to Auto.
Otherwise the line code parameter mimics either of the other two line code settings, AMI or
B8ZS.
2
Repeat this process until you have verified the system settings.
