3 1 - CHANNEL DS3/E3 ATM UNI/PPP COMBO IC GENERAL DESCRIPTION The XRT79L71 is a single channel, ATM UNI/PPP Physical Layer Processor with integrated DS3/E3 framing controller and Line Interface Unit with Jitter Attenuator that is designed to support ATM direct mapping and cell delineation as well as PPP mapping and Frame processing.
For ATM UNI applications, this device provides the ATM Physical Layer (Physical Medium Dependent and Transmission Convergence sub-layers) interface for the public and private networks at DS3/E3 rates.
For Clear-Channel Framer applications, this device supports the transmission and reception of “user data” via the DS3/E3 payload.
The XRT79L71 includes DS3/E3 Framing, Line Interface Unit with Jitter Attenuator that supports mapping of ATM or HDLC framed data.
A flexible parallel microprocessor interface is provided for configuration and control.
