56K V.92 Data, Fax, and Voice Chipset

1. INTRODUCTION

The MD566X Programmer’s Guide describes the software interface of Intel’s V.90/V.92 56K solution. The programmer’s guide includes the AT command sets for data, fax, and voice and the 16C450/16C550A UART emulation. The programmer’s guide should be used with the following Intel publications: the MD566X Datasheet, the IS-101 Voice Application Note, and the Class 1 Fax Application Note. Please note that supported AT commands are firmware revision-dependent.

IMPORTANT: The AT commands in this document are supported by firmware versions 6.06 and above for V.90 and 7.XX for V.92.

Like the earlier solutions from Intel, the V.90/V.92 56K family of products supports a variety of applications without the need of additional firmware development. The MD566X solutions described in Table 1-1are currently available except as noted.
