Motherboard integration of the modemsubsystemhas been problematic to date, in large part due to FCC and
other international telecomcertification processes that delay the introduction of a motherboard when the
modems analog I/O (codec and DAA) circuitry was physically soldered to the board. Resolving
homologation/certification issues for OEMs is one of the key objectives of the AMR specification.
With an open, Industry-standard riser solution, a systemmanufacturer is free to implement audio and/or modem
functions on the motherboard at a lower bill of materials (BOM) cost than would be possible by deploying these
functions in either industry-standard expansion slots or in a proprietary method.
PC-TEL has streamined the traditional modeminto the Host Signal Processing (HSP) solution. Operating
with the Pentiumclass processors, HSP becomes part of the host computers systemsoftware. It requires less
power to operate and less physical space than standard modemsolutions. PC-TEL’s HSP modemis an easily
integrated, cost-effective communications solution that is flexible enough to carry you into the future.
The 2303 chip set is an integrated direct access arrangement (DAA) and Codec that provides a programmable
line interface to meet international telephone line requirements. The 2303 chip set is available in two 16-pin
small outline packages (AC’97 interface on PCT303A and phone-line interface on PCT303W). The chip set
elimnates the need for an AFE, an isolation transformer, relays, opto-isolators, and 2- to 4-wire hybrid. The
2303 chip set dramatically reduces the number of discrete components and cost required to achieve compliance
with international regulatory requirements. The PCT303A complies with AC’97 Interface specification Rev. 2.1.
The chip set is fully programmable to meet world-wide telephone line interface requirements including those
described by CTR21, NET4, JATE, FCC, and various country-specific PTT specifications. The programmable
parameters of the 2303 chip set include AC termnation, DC termnation, ringer impedance, and ringer threshold.
The 2303 chip set has been designed to meet stringent world-wide requirements for out-of-band energy, billing-
tone immunity, lightning surges, and safety requirements.
