Integrity Check
The SPI-2L10 proactively checks whether system configuration or operation information
(PLD) is in compliance with operator commands during system loading or operation, and
also checks whether system settings are OK and there is no problem with call processing.
If the result is not OK, it sends an alarm to the operator. That is, it checks whether system
configuration meets the minimum configuration conditions for call processing or whether
all operation information consists of valid values within an appropriate range. The result is
reported to the operator to help with correction of errors.
OAM Traffic Throttling
The SPI-2L10 provides a function that suppresses OAM related traffic which can occur in
the system depending on the operator command. The OAM related traffic includes fault
trap messages for alarm reports and statistics files that are created periodically.
In a fault trap, the operator can use an alarm inhibition command to suppress alarm
generation for all or some of system fault traps. This helps control alarm traffic.
In a statistics file, the operator can use commands for statistics collection configuration to
control the size of statistics file by disabling collection functions of each statistics group.
Throughput Test
The SPI-2L10 provides a throughput test for the backhaul to the ACR. The SPI-2L10
supports a server and client function for throughput tests.
The operator can set up target IP addresses, test duration, and bandwidths for throughput
tests, and check throughput and loss as test results. However, as the throughput test affects
system performance and call services, it is recommended not to perform the test during in-
service.
System Log Control
The SPI-2L10 provides a log and log control function per application.
An application log can be created by an operator command or its debug level can be set.
The operator can usually keep the log function disabled, and when the log function is
necessary, he can change the debug level (Very Calm, Calm, Normal, Detail, Very Detail)
to enable logging and log save functions.
However, enabling log functions for many applications while the SPI-2L10 is running may
affect the system performance.
