ATM-NTWK (ATM Network Error)
In the ATM PNC configuration, the proprietary Center Stage Switch (CSS) is
replaced by the ATM network. Since the CSS switch nodes are rep laced by the
ATM network in the ATM PNC configuration, the SNI boards are no long er
needed. In plac e of SNI board, the ATM EI boards are connected to an ATM
switch port over a fib er optic cab le. The port on the ATM switch is under the
control of ATM switch maintenance software. Refer to Figure 1-30 in the ‘‘ATM
Tips’ ’ section in Chapter 1 for a schematic of these connec tions.
An error against this MO indicates a problem in the ATM network (including the
ATM switch) that is affecting the service q uality. These error events are reported
by the ATM network to the ATM EI board or are detected by the ATM EI board.
Since these errors are not related to the ATM EI board, these errors are not
reported against the ATM-EI Maintenance Objec t. However, some of these errors
invoke alarms that require action by DEFINITY maintenance, while other log-only
errors require no action.
