S8700 MC
In IPSI connected port networks, the Tone Clock circuit is found on the IPSI circuit pack. In non 
IPSI connected port networks, there is a Tone Clock circuit pack. The following sections 
describe the relationship between the various reliability options and the IPSIs or Tone Clock 
circuits.
S8700 Multi-Connect architecture has three items that can be duplicated: server, IPSI, and 
PNC. Note that duplicated control networks and duplicated IPSIs go together; when the IPSIs 
are duplicated, the control networks must be duplicated. While all items can be independently 
duplicated, the combination of duplicated bearer networks (PNCs) and unduplicated control 
networks is not allowed. Se
 
Duplex-Reliability Configuration
The duplex-reliability configuration shown in 
 has a duplicated server, an 
unduplicated control network, unduplicated IPSIs in the IPSI connected port networks, and an 
unduplicated bearer network. Therefore the Tone Clock is not duplicated in the IPSI connected 
port network. In the non IPSI connected port network, the Tone Clock boards are also not 
duplicated.
