Description of LSB statuses
When an error is detected, automatic maintenance can take fail safe action. The action consists
in changing the security block status. The statuses have the following meaning:
• NOT EQUIP. LSB not equipped in associated configuration table.
• OUT OF SRV LSB does not participate in normal operation because it cannot be accessed by
software. This occurs, for example, when the LSB one step up in the hierarchy
is faulty.
This status is also the initial status of all LSBs before startup.
• DOWNLOAD Processor associated with LSB is being downloaded.
• IN SERVICE LSB participates in normal operation.
• FAULTY Error detected in an LSB function. The LSB is removed from normal operation
by automatic maintenance.
• DISABLED Maintenance operator removed LSB from normal operation using an MMC.
Other special statuses:
• IN PARKING A telephone subscriber did not hang up their set (off-hook)
Configuring maintenance services
The PBX has a built-in maintenance program that offers diagnostic services such as fault
message generation, device status information, and fail safe action. The program monitors the
status of all connected devices. Additionally, when no response or an invalid response from a
device is received, this program disables the faulty device and stores the slot number of that
device in the memory.
Note : No programming is required for enabling diagnostic feature.
Setting up fault information storage
1 Enable the fault record storage feature.
No programming is required for enabling the fault information storage.
2 Assign the type of fault record stored into the fault record memory. By default, certain types
of fault records stored into the memory, such as logbook erased, card down, etc., cannot be
changed.
In menu 4.1 (Administration parameters - Alarm validation), set what kinds of additional
information will be stored into the memory.
