INITIAL START-UP TEST AND STAND ALONE OPERATION
Note: When an HRX is installed, the HLXC indicators
only verify the loop segment between the HLXC and
the HRX.
After the HLXC is installed in the chassis, its STATUS indicator
will initially turn red to indicate the start of self-test diagnostics.
While the self-test is in progress, all indicators will briefly
turn yellow. Then all indicators except STATUS will turn off.
Following the successful completion of the self-test, the HLXC
front panel indicators will appear as follows:
STATUS
RMT/HSKP
LPBK
DS1 LOS/BER
HDSL CONT/SNR
L1 and L2
LOSW/BER
2-60

Red to indicate that a DS1 signal is not
being received by the HLXC.
Red (after a short delay) if loop power
is enabled which indicate the HDSL
loops are open. Off if loop power is
disabled.
Red to indicate that the HDSL loops are not
synchronized (i.e., HLXR is not in service).
If loop 2 is disabled, the L2 indicators will
stay off.
