RCV56HCF PCI/CardBus Modem Designer’s Guide

1. INTRODUCTION

1.1 SUMMARY

The Rockwell RCV56HCF-PCI Host-Controlled Modem Device Family supports high speed analog data, high speed fax, ISDN, DSVD, AudioSpan, speakerphone, audio/voice, and VoiceView operation. It operates with PSTN or ISDN telephone lines in the U.S. and world-wide and is offered in several device models (see Table 1-1).

The modem device set consists of PC PCI bus interface (BIF) and modem data pump (MDP) hardware available in two thin quad flat packs (TQFPs). Host-controlled modem software is also provided.

Operating with +3.3V power, this device set supports 32-bit host applications in such designs as embedded motherboards, PCI half cards, and CardBus cards.

Figure 1-1 illustrates the general structure of the RCV56HCF software and the interface to the RCV56HCF hardware. Figure 1-2 illustrates the major hardware interfaces supported by each model.

The RCV56HCF employs a downloadable architecture so that the user can update MDP executable code.

Using K56flexä technology, the RCV56HCF can receive data at speeds up to 56 kbps from a digitally connected K56flex- compatible central site modem, such as a Rockwell RC56CSM modem. K56flex modems take advantage of the PSTN which is primarily digital except for the client modem to central office local loop and are ideal for applications such as remote access to an Internet service provider (ISP), on-line service, or corporate site. The RCV56HCF can send data at speeds up to V.34 rates.

In V.34 data mode, the modem operates at line speeds up to 33600 bps. Error correction (V.42/MNP 2-4) and data compression (V.42 bis/MNP 5) maximize data transfer integrity and boost average data throughput. Non-error-correcting mode is also supported.

AudioSpan (analog simultaneous audio/voice and data) operation supports a data rate with audio of 4.8 kbps.

SP models support position independent, full-duplex speakerphone (FDSP), as well as digital simultaneous voice and data (DSVD) with speech coding per ITU-T G.729 Annex A with interoperable G.729 Annex B, and SIG DigiTalkä DSVD.

The modem supports fax Group 3 send and receive rates up to 28800 bps and T.30 protocol.

V.80 and Rockwell Video Ready compatible synchronous access modes support host-controlled communication protocols, e. g., H.324 video conferencing.

In voice/audio mode, PCM coding and decoding at 8000 Hz sample rate allows efficient digital storage of voice/audio. This mode supports digital telephone answering machine, voice annotation, and audio recording/playback applications.

AccelerATor kits and reference designs are available to minimize application design time and costs.

This designer's guide describes the modem hardware capabilities and identifies the supporting commands. Commands and parameters are defined in the RCVHCF Command Reference Manual (Order No. 1118).
