Description
This message is used to read the performance statistics associated with a Line
Interface Unit (LIU). The module that wishes to read the statistics must allocate a
message with the correct space in the parameter area, initialize the version field in the
parameter area as shown and send the message requesting a confirmation. All other
fields in the parameter area should be set to zero.
The confirmation message will contain all the statistics written into the parameter field
of the message (unless an error occurred, in which case the status field of the message
will be non-zero).
The statistics can either be read and left unchanged or read and reset in a single
operation depending on the setting of the status field in the request message.
