CHAPTER 2: Introduction

• Compression of data stored in the Fradswitch’s nonvolatile memory, to allow maximum use of the
available storage capacity. The compression is performed by rearranging the data stored in the memory,
to close gaps between data blocks that appear naturally when the stored information is modified.
• Resetting and reloading of the default configuration. This function allows a remote supervisor
to perform these activities, which would otherwise require the dispatching of service personnel.
2.16 Remote System Monitoring
The Fradswitch includes an automatic event-reporting facility that allows the transmission of statistics
and status data to selected X.25 destinations.
The automatically reported information can include periodic system status information, and event reports
according to mask definitions. (The different events are: SYNC status has changed, RTS status has changed,
and power on [Reset].) A report is sent each time an event occurs.
With the Fradswitch’s system-management configuration facility, you can define two destinations, then
decide which information is transmitted to each destination by means of event-reporting masks. It is
therefore possible to program the Fradswitch series to transmit the same reports to both destinations,
and thus to make sure that the reports will reach a management station, or to send different types
of information to different locations.
2.17 Status and Statistics Collection and Reporting Capabilities
The Fradswitch has an advanced statistics-collection and status-reporting facility. This facility permits the
system administrator to display on demand detailed information on the operation and performance of the
X.25 links, and take snapshots that show the status of the Fradswitch series, the utilization of the X.25 links,
and the status of the individual channels. The information obtained by means of the statistics function
allows the system manager to monitor system performance, detect bottlenecks and transmission problems,
decide whether more NVRAM is needed, and troubleshoot on-line user channels.
The information displayed by means of the statistics function includes:
• Fradswitch system data:
Fradswitch identification (its device ID).
The programmed X.25 mode (DTE or DCE).
RAM size.
NVRAM size and current percentage of utilization.
• Fradswitch system status:
The current size (number of characters per buffer) of the data buffers.
The current total number of data buffers, and the number of free buffers.
• System history data, collected since the last resetting of the statistics counters:
