 Overview

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 7 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 

 shows a 

typical IPE trunk card architecture. The various trunk cards differ only in the 
number and types of trunk interface units.
