Tyco Electronics Galaxy SC Controller J85501F-1
Issue 13 February 2001 Feature Descriptions 7 - 22
Alarm Reporting
Mode
All of the configurable parameters for both the data switch port and
alarm should be configured be fore entering alarm reporting mode. After
entering alarm reporting mode the Galaxy SC does the following:
• Wait for data switch alarm signal to go low
• Initialize the data switch port using the configured communication
parameters
• Send attention string to data switch port
• Send password to data switch port
• Send alarm command to data switch port
• Store alarm command response in a buffer
• Send hang-up command to data switch port
• Assert the connected equipment event (call-out if configured)
After doing this the Galaxy SC will poll the connected equipment every
minute to check for changes in the alarm report. Polling will stop when
the alarm signal returns high. At this time the Galaxy SC will retire the
connected equipment event and call out if configured to do so.
If the monitor dsr parameter is set to 1 (yes) and the dsr signal is not
present the Galaxy SC will continue to monitor the alarm signal but will
not retrieve an alarm report from the connected equipment. Alarms from
the connected equipment may be viewed in the call-out report or in the
active alarms report. In these reports the alarm report line for the
connected equipment alarm is followed by the connected equipment’s
alarm response in the following format:
:BEGIN Indicates the beginning of the connected
equipment alarm report
Alarm Report Body Up to 1000 characters received from the
connected equipment
:END Indicates the end of the connected
equipment alarm report
DC Distribution The Galaxy SC supports monitoring of the DC distribution alarm status.
This may be configured through the T1.317 interface using Easy View
and viewed from the T1.317 interface or front panel.
Configuration of this feature involves linking a user-defined event to the
DC Distribution fuse status alarm. For examples on how this
configuration is accomplished please see the section of this manual
entitled “T1.317 DC Distribution Management”.
