XRT72L71
Overview
The XRT72L71 DS3 ATM User Network Interface (UNI)/Clear-Channel Framer is designed to function as either a DS3 ATM UNI or Clear channel framer. For ATM UNI applications, this device provides the ATM Physical Layer (Physical Medium Dependent and Transmission Convergence sub-layers) interface for both the public and private networks at DS3 rates.
