DRL2A OPERATING MODE

If alarm messages cannot be sent to the CPM2 because of

the error, the DRL2A 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 individually acknowledged.

When all alarms are acknowledged, the Line Card sounder

will be silenced.

Up to 256 alarm messages for the printer and computer

will be retained in the DRL2A 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.

1.4 Keep Last Alarm Message

The DRL2A may be programmed to leave the last alarm

message on the display screen until a new message is

received. A typical alarm message is shown below:

L01-1234-312L01-1234-312

L01-1234-312

AlarmAlarm

• “L01” indicates Line Card 01

• “1234” is the account code

• In this example, a 4/3 communication format is used. “3”

indicates an alarm, while “12” is the zone number.

• “Alarm” indicates an alarm event.

• “240” is the event’s location in the event buffer.

The following messages are sent to the printer and computer:

Printer: L0x???????Dx LCardReset

Computer: 0000 A Dx

A hexadecimal digit from 1 to E representing the number

of the Line Card will be sent for each “x” shown above.

After these start-up transmissions, the Line Card enters the

Stand-By Mode and monitors the telephone line and the

CPM2. Depending on the system’s status, the following

conditions will be indicated:

• Line fault

• Shutdown of Line Card communication with CPM2

• CPM2 error; display alarm message

• Keep last alarm message

• System in stand-by

1.1 Line Fault

The DRL2A verifies the telephone line voltage every 10

seconds. The “Line Fault” light will come ON after two

successive line verifications indicate irregular telephone line

voltage. This message will be displayed:

-L01-Digital Rec-L01-Digital Rec

-L01-Digital Rec

<<-Line Fault->><<-Line Fault->>

<<-Line Fault->>

If the Line Check option is enabled, the following information

will be transmitted to the printer and computer:

Printer: L01???????20 Line Fault

Computer: 0000 A 20

If the Line Check option is disabled, the DRL2A will not

send the report to the printer or computer. Refer to “DRL2A

Line Card Options Programming” for information on enabling

the Line Check option.

When the line condition returns to normal, the “Line Fault”

light 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???????30 Line Restr

Computer: 0000 R 30

1.2 Shutdown of Line Card Communication with CPM2

A Line Card may be temporarily removed from CPM2 polling

for testing and maintenance purposes (refer to “CPM2 Utility

Modes” for information on shutting down a line card). While

in the shutdown mode, the Line Card will retain up to 256

alarm messages in its event buffer. When the Line Card is

shut down, the “Trouble” light will come ON and this message

will be displayed:

-L01-Digital Rec-L01-Digital Rec
