Overview

Operation

This section describes how trunk cards fit into the CS 1000E, 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
parameters.

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.
