Circuit Card Description and Installation
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 3 on
page 32 .
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)
