Description
General
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.
Parallel interface operation, including cellular and
GSM support, is selected by PARIF input high. Serial
interface operation is selected by PARIF input low.
Cellular operation is selected by LINE/CELL input
low. GSM operation is selected by LINE/GSM input
low.
