ATM-NTWK (ATM Network Error)
In the ATM PNC configuration, the proprietary Center Stage Switch (CSS) is
replaced by the ATM switch. Since the CSS switch nodes are replaced by the
ATM switch in the ATM PNC configuration, the SNI boards are no longer needed.
In place of SNI board, the ATM_EI boards are connected to an ATM switch port
over a fiber optic cable. The port on the ATM switch is under the control of ATM
switch maintenance software. Refer to Figure 5-6
in the ‘‘ATM Tips’’ section in
Chapter 5 for a schematic of these connections.
An error against this MO indicates a problem in the ATM network (including the
ATM switch) that is affecting the service quality. These error events are reported
by the ATM network to the ATM-EI board. Since these errors are
not
related to the
ATM-EI board, these errors are not reported against ATM-EI Maintenance Object.
These log-only errors require no action by DEFINITY maintenance software.
Error Codes and Aux Data values
The Cause Code and Error Type information from the ATM network is shown in
Table 9-95
. These are the errors that are logged when the Cause Code or Error
Type is received from the network. Six-digit codes against the ATM-NTWK
maintenance object are possible:
■ The first two characters represent ATM
■ The next two characters stand for the connection number
■ The last character indicates if it is A or B side of the PNC.
If the ATM-NTWK Maintenance Object receives more than 6 errors, the oldest
errors are overwritten unless it has been less than 6 minutes since the oldest
reported error.

connection number can be converted into a board location by the command display atm
pnc UU, which shows the translations for the board that reported the ATM network error.
P
indicates if the ATM-EI board (reporting the ATM network error) is the A side or the B side
of the PNC. If the system is simplex, only A is valid.
