The GSM Alarm Status Table

The GSM SNMP agent makes a special MIB object available for polling by third party
managers. This object is the GSM alarm status table. It contains statuses for all the Densité and
Imaging card alarms contained in the GSM, and is defined in the GSM-MIB file.

The alarm status table (statusTable) is composed of alarm entries (statusEntry) which are
categorized by device index (deviceIndex), slot index (slotIndex) and status type index
(trapIndex)

• The device index is a unique number attributed to each Imaging or Densité frame the first

time it is discovered by the GSM.

• The slot index corresponds to the physical slot containing a card.

• The trap index maps to a type of alarm such as freeze detect or black detect.

The different alarm types available for all Miranda Imaging and Densité Cards are enumerated
in the MIRANDA-MIB file.

The table also contains the type, the name and the status of each alarm.

• The type field corresponds to the long ID of a card. This is a unique identifier made up of a

device identifier (Application Server host name, Densité frame name, or COM port number
for Imaging frames) plus the slot number and the card model number.

• The name field contains a human readable label for the alarm name.

• The status field contains the status of the alarm.

Device Index

The iControl GSM uses auto-discovery to find the Miranda Densité and Imaging frames
present in the system. These devices may originate from the Application Server where the
GSM is running, or from other Application Servers that the GSM has discovered.
