High-Reliability Configuration
Critical-Reliability Configuration
The critical-reliability configuration shown in
has full duplication of
the following options: servers, control networks, IPSIs and PNCs (bearer
networks). As with the high-reliability configuration, this configuration also
requires that IPSI-connected port networks have duplicated IPSIs. This
configuration also requires that the non-IPSI-connected port networks have
duplicated Tone-Clock boards (either TN2182 or TN780).
