Section 5 - DRL2000 Operating Mode
5.1
DRL2000 Standby Mode
After start-up the Line Card enters the Stand-by Mode
and monitors the telephone line and the CPM2000.
Depending on the system's status, the following condi-
tions will be indicated:
• Line Fault light
• Trouble light: of Line Card communication problem with
CPM2000
5.1.1 Line Fault
The DRL2000 verifies the telephone line voltage. The 'Line
Fault' light will come ON when the voltage drops below
12V.
If the Line Check option is enabled, the following informa-
tion will be transmitted to the printer and computer:
• Printer:
Jul 17 1998-08: 08: 28-SS/OO-SG-RR-LLL-0000-
PHONE LINE TROUBLE
• Computer:0RRLLL[#0000¦NLTSSOO][DC4]
A hexadecimal number from 00 to 0B representing the
slot number of the Line Card will be sent for each 'O'
shown above.
A hexadecimal number from 01 to FE representing the
shelf number of the Line Card will be sent for each 'S'
shown above.
If the Line Check option is disabled, the DRL2000 will not
send the report to the printer or computer. Refer to
'DRL2000 Programmable Features' 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 trans-
mitted to the printer and computer:
• Printer:
Jul 17 1998 - 08: 08: 35-SS/OO-SG-RR-LLL-0000-
PHONE LINE RESTORE
• Computer:0RRLLL[#0000¦NLRSSOO][DC4]
5.1.2 CPM2000 Error
If the DRL2000 cannot detect CPM2000 polling, the trou-
ble light will come on.
If alarm messages cannot be sent to the CPM2000
because of the error, the DRL2000 will start buffering
incoming calls.
Up to 256 alarm messages for the printer and computer
will be retained in the DRL2000 event buffer. When the
event buffer is full, the line card will stop answering the
calls.
When the CPM2000 Error condition is corrected, the
alarm messages in the event buffer will be transmitted to
the CPM2000 with the corresponding time/ date the
alarm have been received.
5.2
DRL2000 Cold Start-up
To perform a Cold Start-up, press the [F1] and [F2] buttons
simultaneously for 10 seconds after a power up.
5.3
Communications in Progress
5.3.1 Data Reception
During data reception, the on-line LED will turn on. The
DRL2000 decodes all information received and stores the
information in its Event Buffer. When a valid signal is
received, the DRL2000 sends a kiss-off signal and trans-
mits the decoded alarm signal to the computer and then
to the printer through the CPM2000.
The DRL2000 will send each message it receives to the
printer for review by the system operator. Two messages
may be sent to the printer to indicate reception problems:
the 'Fault Data' and 'Fault Call'.
5.3.2 Fault Data Message
When this problem is encountered, the following informa-
tion is transmitted to the printer and the computer:
• Printer:
Jun 25 1998-11:18:07-SS/OO-SG-12-234-0000-
INVALID REPORT
• Computer: 012234[#0000¦NYNSSOO][DC4]
This output for account code '0000' indicates that data
has been received, but is not valid (for example, there are
unmatched rounds or wrong parity).
5.3.3 Fault Call
When this problem is encountered, the following informa-
tion is transmitted to the printer and the computer:
• Printer:
Jun 25 1998-11:18:07-SS/OO-SG-12-234-0000-
COMMUNICATION FAIL
• Computer: 0RRLLL[#0000¦NYCSSOO] [DC4]
This output indicates that a call was received, but no data
was detected. The call may have been a wrong number,
or the calling control panel was unable to connect with
the receiver's handshakes.
5.3.4 Caller ID
When Caller-ID is enabled:
• Printer:
