ATM Line Card (T-Series)
The ATM line card actually 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
host system provides the power, initialization, and control for the PHY card. The PHY
card is used with an ATM segmentation and reassembly (SAR) or cell-switching function.
