Reset packets are sent to reinitialize a virtual c ircuit in the data transfer state
when specified errors are detected on the virtual circuit.
Errors are conveyed in the Cause and Diag nostic fields of these pac kets. The
Cause Field indicates the reason for the error and the Diagnostic Field provid es a
further explanation of the error. Cause and d iagnostic c odes can be ge nerated
by either a network (DCE) or a network user (DTE). Code values are segmented
such that those generated b y a DTE or a DCE can be distinguished. Cause
codes are further segmen ted to distinguish b etween causes delivered to a DTE
which were generated b y a private or public network. Essentially, a private
network utilizes the PDN cause code values b y offsetting the PDN value by 128.
DEFINITY G3 assumes the role of a private network when generating the c auses
whether its side of the interface is administered as a DTE or a DCE.
A port administration op tion allows logging of X.25 errors to be selectively turned
on or off for individual por ts. A customer may choose to turn on error logging only
for important network interfaces and hosts in order to cap ture a complete error
history about these ports. For less c ritical interfaces, a c ustomer may choose to
turn off error logging to prevent c luttering the system error log. In this case, error
logging c an be turned on as needed to diagnose trouble reports with the
interface. Error logging i s not turned on as the administrative d efault for this
option on X.25 Packet Gateway ports.
