Using the Memory Space Accounting (MSAC) feature, defined in GR-82-CORE Issue 10, the DSC - SP2000 Platforms provides accounting of the amount of memory space allocated to monitored objects such as Signaling Channels (SIGCH), Annex A Channels (ANNEXA), MTP3 NAs (NA), linksets (LINKSET), and so on.
The following figure shows the Network Appearance Selection screen that lists the Network Appearances (NAs) on the system. Clicking the MSA button displays the monitored objects for the NAs (see Figure MSA Selection Screen).
The MSA information allows you to assess if there is enough memory space for all objects prior to provisioning the system, and also allows you to monitor these objects during system operation.
In this guide, the amount of memory space allocated refers to the object count.
Three alarm threshold values can be configured (see Table MSA Values) to indicate if a threshold has been exceeded. When the current size of a tracked object increases and crosses a threshold, an alarm is triggered and the event is recorded in the system log (ptisyslog) file. When the current size of a tracked object returns below the alarm threshold, a cleared alarm message is recorded in the system log (ptisyslog) file.
MSA is set to ENABLED by default for all applications.
The following figure shows the ptisyslog file with entries showing a minor alarm raised and cleared for the SIGCH object.
The following figure shows a typical MSA configuration screen.
The various MSA objects supported for the DSC Platform are listed at the top of the page under Additional Sections.
