1.0 Introduction
This document provides reference information for the evaluation testing of an external USB modem based
on Host Signal Processing Data/Fax Modem Technology. The evaluation HSP USB Modem™ eliminates
the redundant hardware parts found in most modems today. These include the data pump, a controller, an
additional UART and external memory as required in a conventional approach. In addition, the complete
HSP solution allows an external modem to be upgraded with enhancements and features through software
upgrades rather than a chip change or board swap.
