Updating static data

Three types of updates provide the inactive unit of the RSC-M with data to
control maintenance and call processing. The three types of updates are:

static data update

bulk data update

dynamic data update

Static data update
Static data holds RSC-M and AN configuration information, like the
association between RSC-M P-side ports and AN link numbers. The CM
sends this information to the two units of the RSC-M. The CM sends this
information when a return to service (RTS) on the CM occurs. The CM also
sends this information to an in-service (InSv) RSC-M when tables RCCINV
or LNINV change.
When operating company personnel alter configuration information, the
system sets the RSC-M to an in-service trouble (ISTb) condition. The
system informs personnel that a static data mismatch is present. The system
provides information on the appropriate way to correct the mismatch.
Static data defines the RSC-M configuration and does not change when calls
connect and disconnect. When static data in the host and the RSC-M do not
match, data corruption can result. The host determines that a line is present
when the RSC-M determines that the line is not present. This mismatch
results in the loss of calls.
Feature Node Table Sync Redesign changes the method that clears the ISTb
condition for XPMs. These XPMs have software loads that support
configuration data table (CDT) management.
Each XPM unit has tables that contain information about nodes to which the
XPM connects and terminals that the XPM uses. The two systems that
determine unit table mismatches are:
mate unit matching that compares the inactive unit tables with the active
unit, and sets the XPM ISTb when a mismatch occurs. The active unit
sends table mapping information to the inactive unit during updates. The
use of the NODATADYNC option can busy (BSY) and RTS an inactive
unit with an ISTb condition. This action causes a configuration
download to that unit.
Note: Feature XPM Node Table Sync Redesign changes the execution
of the command RTS with the NODATASYNC option.
