IPSV-CTL (IP Server Interface Control)
2. IPSI’s firmware notifies software of loss of clock.
3. Software interchanges Archangel.
4. Software interchanges PKT-INT.
5. The port-network is COLD started.
Active IPSI has a faulty PKT-INT.
1. Software detects faulty PKT-INT.
2. Software interchanges PKT-INT.
3. Software interchanges Archangel.
4. Software interchanges Tone-Clock.
Active IPSI has a faulty Archangel.
1. PKT-INT detects dead EAL and reports it to software.
2. Software interchanges Tone-Clock.
3. Software interchanges Archangel.
4. Software interchanges PKT-INT.
Both IPSIs are healthy (pled interchange sequence).
1. Software interchanges Tone-Clock.
2. Software interchanges Archangel.
3. Software interchanges PKT-INT.
If both of a PN’s IPSIs have faulty Tone-Clock, then the PN is out of service.
If both of a PN’s IPSIs have faulty EAL and/or PKT-INT, then the PN “falls back” to EI-EAL mode
of operation, where:
● The PN’s Expansion Interface circuit pack (EI) provides Archangel functionality
● Another PN’s IPSI provides PKT-INT functionality
For details, see EXP-INTF (Expansion Interface Circuit Pack).
The following tables show the valid combinations of IPSIs and EIs providing Tone-Clock,
PKT-INT, and Archangel function:
● Table 143: IPSI A is Active
● Table 144: IPSI B is Active
● Table 145: IPSI A Provides Tone-Clock; Fall-Back to EI-EAL
● IPSI B Provides Tone-Clock; Fall-Back to EI-EAL
