Reset packets are sent to reinitialize a virtual circuit in the data transfer state
when specified errors are detected on the virtual circuit.
Errors are conveyed in the Cause and Diagnostic fields of these packets. The
Cause Field indicates the reason for the error and the Diagnostic Field provides a
further explanation of the error. Cause and diagnostic codes can be generated
by either a network (DCE) or a network user (DTE). Code values are segmented
such that those generated by a DTE or a DCE can be distinguished. Cause
codes are further segmented to distinguish between causes delivered to a DTE
which were generated by a private or public network. Essentially, a private
network utilizes the PDN cause code values by offsetting the PDN value by 128.
DEFINITY G3 assumes the role of a private network when generating the causes
whether its side of the interface is administered as a DTE or a DCE.
A port administration option allows logging of X.25 errors to be selectively turned
on or off for individual ports. A customer may choose to turn on error logging only
for important network interfaces and hosts in order to capture a complete error
history about these ports. For less critical interfaces, a customer may choose to
turn off error logging to prevent cluttering the system error log. In this case, error
logging can be turned on as needed to diagnose trouble reports with the
interface. Error logging is not turned on as the administrative default for this
option on X.25 Packet Gateway ports.
