Duplication for Reliability
The S8700 Multi-Connect architecture has duplicated components to increase the
reliability of the system. If one duplicated component fails, the other can take over
without impacting service or minimizing the impact. Which components are
duplicated in your system depends on the level of reliability chosen for your
configuration: duplex, high, or critical reliability. The following sections describe
these different reliability levels and their configurations.
For more details about how the system is able to interchange between duplicated
components, see
Chapter 8, ‘‘Maintenance-Object Repair Procedures’’
. To
troubleshoot interchange problems, also see
Chapter 4, ‘‘Alarms, Errors, and
Duplex-Reliability Configuration
In a duplex-reliability configuration, only the media server is duplicated; the IPSIs,
control networks and bearer networks are not. Multiple Ethernet switches may be
present in order to provide sufficient Ethernet connections to the IPSI boards in
the port network.
