Introduction Hardware Overview
ATM Multi-Rate Line Card
The ATM Multi-rate line card houses various Physical Layer (PHY) interface cards in its two available slots. ATM
PHY cards provide the media-specific portion of an ATM interface to support ATM connectivity across multiple
platforms using different media types. The line card provides the power, initialization, and control for the PHY card.
Figure 2-24 shows the front panel of the ATM Multi-rate line card.

See Section 3.3.9, "Installing ATM Physical Media Cards (PHYs)" for instructions on installing PHYs into the ATM
Multi-rate line card.
The ATM Multi-rate line card has two available slots. Each slot accepts the following PHY interface modules:
