Line cards 21

Operation

This section describes how line cards fit into the CS 1000E, CS 1000M,

and Meridian 1architecture, the busses that carry signals to and from the

line cards, and how they connect to terminal equipment. These differences

are summarized in Table 2 "IPE module architecture" (page 21).

Host interface bus

Cards based on the IPE bus use a built-in microcontroller. The IPE

microcontroller is used to do the following:

•

perform local diagnostics (self-test)

• configure the card according to instructions issued by the system

•

report back to the system information such as card identification

(type, vintage, and serial number), firmware version, and programmed

configuration status)

IPE line cards all share a similar architecture. Figure 2 "Typical IPE analog

line card architecture" (page 23) shows a typical IPE line card architecture.

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.
