Maintenance-Object Repair Procedures
Critical-Reliability Configuration
The critical-reliability configuration shown in
following options: media servers, control networks, IPSIs and PNCs (bearer
networks). As with the high-reliability configuration, this configuration also
requires that IPSI-connected EPNs have duplicated IPSIs. Since the IPSI's are
duplicated in this configuration, the PKT-INT circuits are also duplicated.
Figure 8-76. Critical-Reliability Configuration
Packet Interface Service Operations
The following sections provide more background information about service
operations for the Packet Interface circuit.
Administration
PKT-INTs are automatically administered as a component of an IPSI circuit pack.
See add ipserver-interface, remove ipserver-interface, test packet-interface,
status packet-interface, and reset packet-interface.
