1 Introduction
The aTCA-RN720 is a Rear Transition Module that provides two QSFP and four SFP+ service ports.
The aTCA-RN720 is designed to be paired with the aTCA-N700 Traffic Management Blade, but it can
be paired with any front blade which shares the same Zone 3 specifications.
When an ATCA front blade has high capacity processing capability requiring additional I/O ports
through the RTM, the aTCA-RN720 can meet such needs by loading aggregated 120Gbps service
ports to the front blade with QSFP and SFP+ ports.
This document is intended to provide a basic usage guide to customers using the aTCA-RN720
blade. Shown in Table 1-1 is a selected set of abbreviations that are frequently used throughout the
document.
