Overview
Host interface bus
Cards based on the IPE bus use a built-in microcontroller. The IPE
microcontroller is used for the following:
•
to perform local diagnostics (self-test)
•
to configure the card according to instructions issued by the system
processor
•
to report back to the system processor information such as card
identification (type, vintage, and serial number), firmware version, and
programmed configuration status.

IPE trunk cards all share a similar architecture.
IPE trunk card architecture" (page 49)
shows a typical IPE trunk card
architecture. The various trunk cards differ only in the number and types of
trunk interface units.
