Overview Page 29 of 894

When installing line cards, follow these general procedures:

•Configure the jumpers and switches on the line card (if any) to meet system needs.

•Install the line card into the selected slot.

•Install the cable that connects the backplane connector on the IPE module to the module I/O panel.

•Connect a 25-pair cable from the module I/O panel connector to the Main Distribution Frame (MDF).

•Connect the line card output to the selected terminal equipment at the MDF.

•Configure the individual line interface unit using the Analog (500/

2500-type) Telephone Administration program LD 10 for analog line interface units and Multi-line Telephone Administration program LD 11 for digital line interface units.

Once these steps have been completed, the terminal equipment is ready for use.

Operation

This section describes how line cards fit into the CS 1000S, 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 Table 2 on page 30.

Host interface bus

Cards based on the IPE bus have a built-in microcontroller. The IPE microcontroller is used to do the following:

•perform local diagnostics (self-test)
