IPSV-CTL (Ipserver Interface Control)

Error code of 30320 with aux data 60 indicates that software requested the

archangel move to the A-side IPSI as a result of a PKT-INT fault class

improvement.

Error code of 31041 with aux data xx indicates a software requested interchange

from the A-side IPSI to the B-side IPSI leaving the archangel on the IPSI due to a

loss of TDM clock.

IPSI Interchange (Duplicated IPSIs)

Software will take action upon any fault that affects the IPSI and attempt to

interchange to the healthier IPSI. In addition, when neither IPSI is completely

healthy to provide clock, packet interface and archangel, one IPSI will be chosen

to be the clock, and the archangel will move to the EI. Moving the archangel's

functionality to the EI requires another port network to have a healthy IPSI, and

this port network to have an EI. The exact order of action taken will vary

depending on the fault being processed, as well as the existing state of health

(SOH) of the IPSIs in the PN. An IPSI interchange (if necessary) will always

happen before a control change (moving of the archangel to/from IPSI/EI). If both

IPSIs are equally healthy, software preferentially migrates to the A-side IPSI.

However, this preferential migration is not done if craft has set to a B-side IPSI.

Craft can also demand an interchange of IPSIs in one or every PN from the SAT.

The command set ipserver-interface Uc is used to interchange a specific IPSI.

In addition, set ipserver-interface a-all | b-all can be used to interchange every

IPSI in the system to the A-side or B-side respectively. This is particularly useful if

preparing for a control-network outage. For a planned interchange of IPSIs, the

following steps occur. The:

1. Going active IPSI is marked as active, the going standby is marked as

2. Tone-Clock is migrated. This includes tone generation as well as TDM

3. Archangel is migrated to the newly active IPSI.

4. PKT-INT on the newly active IPSI is made active. Every link is migrated

between IPSIs.
