Section 5 - DRL2E Operating Mode
5.1
DRL2E Standby Mode
When the line card is operating normally, this message
will be displayed:
DRL2E–Line #D
Unit in Standby
5.1.1 Line Fault
The DRL2E verifies the telephone line voltage every 10
seconds. The “Line Fault” light will come ON after two
successive line verifications indicate irregular tele-
phone line voltage. This message will be displayed:
DRL2E-Line #D
<<-Line Fault->>
If the Line Check option is enabled, the following
information will be transmitted to the printer and
computer:
Printer:L01-0000-PHONE-LINE-TROUBLETIME:DATE
(printer option set to 03)
Computer: 0RRL[#0000 | NLTRRL]
NOTE:
The first RRL is subject to the line card
length option. The second RRL is the receiver and
line card number, both in HEX.
If the Line Check option is disabled, the DRL2E will
not send the report to the printer or computer. Refer
to “DRL2E Programmable Features” for information on
enabling the Line Check option.
When the line condition returns to normal, the “Line
Fault” LED will be shut OFF.
If the Line Check option is enabled and the telephone
line returns to normal, the following information will
be transmitted to the printer and computer:
Printer:L01-0000-PHONE-LINE-RESTORALTIME:DATE
Computer: 0RRL[#0000 | NLRRL]
NOTE:
The first RRL is subject to the line card
length option. The second RRLL is the receiver and
line card number, both in HEX.
5.1.2 CPM2 Error; Display Alarm Messages
If the DRL2E cannot detect CPM2 polling and there
are no alarm events in the event buffer, this message
will be displayed:
DRL2E–Line #D
<<-CPM ERROR->>
If alarm messages cannot be sent to the CPM2
because of the error, the DRL2E will display the oldest
message which has not been manually acknowledged.
The “Alarm” light will FLASH and the sounder will beep
if the “Mute Buzzer” option is programmed as [00],
[02] or [03].
When a CPM2 error is present, each alarm must be
manually acknowledged. Press the [ACK/FUNCTION]
button to acknowledge the alarm and silence the line
card sounder. If several alarms have been received but
cannot be sent to the CPM2, they will have to be indi-
vidually acknowledged; when all alarms are acknowl-
edged, the line card sounder will be silenced.
Up to 128 alarm messages for the printer and com-
puter will be retained in the CPM2 event buffer. When
the event buffer is full, the oldest messages will be
deleted as new events are recorded.
When the CPM2 error condition is corrected, the
alarm messages in the event buffer will be transmitted
to the CPM2.
5.1.3 Keep Last Alarm Message
The DRL2E may be programmed to leave the last
alarm message on the display screen until a new mes-
sage is received. A typical alarm message is shown
below:
0000–PHONE LINE
TROUBLE
28
“0000” is the “internal” account code.
“28” is the event’s location in the event buffer.

TION] button will display the first function menu:
