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

Green to indicate that the self-test was

 

successfully completed.

RMT/HSKP

Off.

LPBK

Off.

DS1 LOS/BER

Red to indicate that a DS1 signal is not

 

being received by the HLXC.

HDSL CONT/SNR

Red (after a short delay) if loop power

 

is enabled which indicate the HDSL

 

loops are open. Off if loop power is

 

disabled.

L1 and L2

Red to indicate that the HDSL loops are not

LOSW/BER

synchronized (i.e., HLXR is not in service).

 

If loop 2 is disabled, the L2 indicators will

 

stay off.
