This section describes how trunk cards fit into the CS 1000S, CS 1000M, and
Meridian 1 architecture, the buses that carry signals to and from the trunk
cards, and how they connect to terminal equipment. See Table 8 for IPE
parameters.
Cards based on the IPE bus have 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 have a similar architecture. Figure 11 on
typical IPE trunk card architecture. The various trunk cards differ only in the
number and types of trunk interface units.
