The TN2312AP IPSI and TN2312BP circuit packs are duplicated in a high- or critical-reliability 
system. As part of duplicated IPSIs, PKT-INTs, Archangels, and Tone-Clocks are also 
duplicated. However, to simplify recovery algorithms, only one IPSI can be “active” in a given 
PN. The one exception to this rule is the IPSI’s tone-detection module. Both IPSIs may have 
active tone detectors.
Note:
Note:
The TN2312BP IPSI is a replacement for the TN2312AP IPSI and can be used 
anywhere a TN2312AP is used. The TN2312AP is not compatible with CMC1and 
G650 media gateways.
During an IPSI interchange, the IPSI’s PKT-INTs, Archangels, and Tone-Clocks are temporarily 
distributed between the two IPSIs. During stable operation, the active PKT-INT, Archangel, and 
Tone-Clock must all reside on the same IPSI.
S8700 IP
: In an S8700 IP-connect configuration, IPSI capabilities are provided by a single IPSI, 
not shared by two IPSIs. All IPSI capabilities that are functioning are provided by a single IPSI in 
an IP-connect configuration. This differs from multi-connect configurations in which the EAL can 
be in an expansion interface (EI) circuit pack during a recovery operation. (S8700 IP-connect 
configurations do not contain EI circuit packs.)
Each IPSI’s state of health (SOH) is based on the following elements in descending order of 
priority:
Note:
Note:
A low priority fault indicates a better state-of-health than a high priority fault. For 
example, a clock fault on an IPSI is more severe that a PKTINT fault on an IPSI.
