LRR Line Card Mode
When configured for LRR Line Card Mode, subscriber alarm messages received on the
10BaseT connection are passed to a 685-5 line card installed in a 685 Digital Alarm Receiver
or a LRR Line card in an MX8000.
New alarms are briefly displayed in the 7810iR New Alarm window with no audible alert.
When the line card receives and acknowledges the alarm message, the 7810iR automatically
moves the current message into the Alarm History window. The next alarm in the New
Alarm buffer will be displayed in the New Alarm window.
Both the New Alarm window and the Alarm History window are first-in, first-out (FIFO)
buffers that are limited to 100 entries. Once 100 messages have been received, the next
message received will push the oldest alarm off the list. There is no method to save or
archive messages in these buffers.
If the Fail to Manual option is selected during the 7810iR programming, the 7810iR will
allow the operator to select Manual Mode when communication with the line card is lost.
When communication is restored, the 7810iR will send up to 100 unreported messages to the
line card.
If the Fail to Manual option is not selected, a loss of communications between the 7810iR and
the line card will result in AlarmNet being blocked, generating an error message. This
makes all incoming messages from AlarmNet undeliverable or bounced. In this condition,
AlarmNet will route all subscriber message traffic to the secondary CS.
