The TN2312AP IPSI and TN2312BP IPSI 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, only one IPSI can be “active” in a given PN. The only 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.
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-series IP-PNC: Every PN has its own IPSI, unlike Fiber-PNC, which can share IPSI
resources through the CSS/ATM network.
Each IPSI’s state of health (SOH) is based on the following elements in descending order of
priority:
Table 142: Fault classes and IPSI interchanges
Fault Class Circuit pack function that is monitored Priority
Clock Clocking signal for the TDM bus 1 (highest)
PKTINT Sending and receiving packet control messages 2
EAL Noting the state of the expansion archangel link (up or down) 3
Generation Generating tones 4 (lowest)
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.
The active server’s maintenance software is responsible for maintaining the SOH of both the
active and standby IPSI in each PN. If an active IPSI’s SOH is lower than the standby’s, IPSI
interchange is initiated. The following list contains failures and actions that cause an
interchange.
Active IPSI has a faulty Tone-Clock.
1. IPSI’s hardware detects loss of clock, and its firmware initiates clock interchange.
