Description
The SmartACFL device set, comprised of separate microcontroller (MCU), modem data pump (MDP), and line side device (LSD) devices, provides the processing core for a complete modem design. The optional Voice Codec (VC) supports voice/full-duplex speakerphone (FDSP) operation with interfaces to a microphone and speaker and to a telephone handset/headset (S models). The S model can also be ordered with an RCDSVD Speech Codec Processor (SCP) in a 100-pin PQFP to support DSVD.
Modem operation, including dialing, call progress, telephone line interface, telephone handset interface, voice/speakerphone interface, and host interface functions are supported and controlled through the V.250, V.251, and V.253-compatible command set.
The modem hardware connects to the host via a parallel, serial, or PC Card interface. The OEM adds discrete components as required by the modem model and the application to complete the system (Table 1). These components may include a crystal circuit, EEPROM, DIB components, telephone line interface, optional voice/speakerphone interface, and optional cellular/GSM interface.Specifications and features
