System Settings Screen

Enter its character key, which is shown inside the parenthesis within each parameter description. This causes
the screen to refresh with the new settings.

to exit, then
to confirm. The newly selected parameters
are now activated.
DS0 Blocking Option
To set the DS0 Blocking option from the Main screen:
1
Press to select the Systems Settings screen (see
2
Press
for the DS0 blocking selection. The DS0 channels are blocked or unblocked by entering each channel
number. Multiple channels can be selected by inserting a space between each entry.
3
After all the new settings have been made, press
for (Exit) then
to (Confirm). The new choices are now
installed.
If DS0 blocking is invoked in a HiGain system that has an earlier version HRU that does not support the blocking
option, blocking only occurs at the DSX-1 output of the HLU-431. The HRU DS1 output will not be blocked.
Also, all blocked channels are temporarily unblocked for all HiGain system loopback tests for all DS1 blocking
settings. This allows the standard full bandwidth T1 loopback tests to be performed for all DS0 blocking settings.
