Normal Indications
LCD
If no ON-state alarm* is stored in the alarm buffer (ALM indicator off),
HCD-E1 continues to display the last user-selected display. If there are
ON-state alarm messages stored in the alarm buffer (ALM indicator lights)
and neither PORT DIAG nor HDSL DIAG screen is displayed, the top row
displays the message ALARM BUFFER.
In addition, HCD-E1 will automatically abort the current activity (except
PORT DIAG and HDSL DIAG) and will redisplay the ALARM BUFFER
message if no front-panel button is pressed for one minute.
When the top row shows ALARM BUFFER, the second row displays the
following information:
•
If there are no ON-state alarm messages stored in the alarm buffer, the
second row shows EMPTY.
•
If the alarm buffer contains ON-state alarms, HCD-E1 displays SCROLL in
the left-hand field of the second row, and CLEAR in the right-hand field.
* For explanation of the term, instructions on displaying and clearing the alarms, refer
to Section 5.2, Status Indications and Alarms, in Chapter 5.
LEDs
During normal operation, all the HCD-E1 front-panel indicators are off.
•
The TST indicator lights when a test is active. The test type can be
displayed by entering the TEST OPTIONS (Chapter 5).
•
The E1 LOS LOC indicator lights when the E1 port loses frame
synchronization to the incoming signal (in the UNFRAMED mode, the
indicator lights when the incoming signal is corrupted or missing).
•
The E1 LOS REM indicator of a link lights when the equipment
connected to the E1 port reports loss of synchronization. This indication
is not available when the UNFRAMED mode is selected.
•
The HDSL LOS indicator lights when the circuits of the corresponding
HDSL line lose synchronization to the incoming signal.
•
The ALM indicator lights when ON-state alarms are stored in the
