1.3 TECHNICAL OVERVIEW
1.3.1 General Description
Modem operation, including dialing, call progress, telephone line interface, telephone handset interface, PDC High
Speed/GSM 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 processor via a PCI/Mini PCI bus interface. The OEM adds a crystal circuit,
EEPROM, DIB and LSD power rectifier and filter components, telephone line interface, optional telephone handset interface,
optional PDC high speed/GSM interface, optional voice/speakerphone interface, and other supporting discrete components
as required by the modem model and the application to complete the system.
1.3.2 Host Modem Software
The host modem software performs the following tasks:
1. General modem control, which includes command sets, fax Class 1, TAM, voice/speakerphone, error correction, data
compression, GSM protocol stacks, PDC high speed data protocol stacks and phone drivers, and operating system
interface functions.
2. Modem data pump signal processing, which includes data and facsimile modulation and demodulation, as well as voice
sample formatting, is performed by the host processor using Conexant SoftK56 technology.
3. SmartDAA control, which includes HSD SmartDAA Interface control, LSD configuration and control, telephone line
interface parameter control, and telephone line impedance control.
Configurations of the modem software are provided to support modem models listed in Table 1-1.
