Intelligent Peripheral Equipment

IPE line cards all have a similar architecture. Figure 2 on page 32 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.

Signaling data is information directly related to the operation of the telephone line. Some examples of signaling commands include:

•off-hook/on-hook
