Once these steps are complete, the terminal equipment is ready for use.
Operation
This section describes how line cards fit into the CS 1000E, CS 1000M, and
Meridian 1 architecture, the busses that carry signals to and from the line
cards, and how they connect to terminal equipment. These differences are
summarized in
Host interface bus
Cards based on the IPE bus use a built-in microcontroller. The IPE
microcontroller is used to do the following:

IPE line cards all share a similar architecture.
line card architecture" (page 23)
The various line cards differ only in the number and types of line interface
units.
The switch communicates with IPE modules over two separate interfaces.
Voice and signaling data are sent and received over DS-30X loops, and
maintenance data is sent over a separate asynchronous communication
link called the card LAN link.
Signaling data is information directly related to the operation of the
telephone line. Some examples of signaling commands include:
