The Analog Front End (AFE) and the Digital Signal Processor (DSP) provide the acoustic interface and automatic gain control and performs voice signal processing, like echo cancellation, voice coding and compression, tone detection and generation, as well as conferencing.
The Ethernet module provides two physical interfaces for connection to the LAN and the PC. Additionally, the Ethernet module integrates two MAC units and a 3-port switch. This module handles the voice packets from the LAN and transfers data packets between the PC and the LAN. Also, network functions such as flow control, voice packet prioritization, and dynamic data buffering are handled by the Ethernet module.

The powerful MIPS CPU core executes its software from external memory via the instruction and data caches and can be seen as the central control unit of the IP phone. The CPU core provides the platform for the real time operating system (RTOS) on top of which all protocol stacks for the network interface and the telephony signaling run. It also controls all user interface functions. The peripherals primarily provide interfaces, including connection of user control functions of the telephone such as keypad, display, and LEDs.
The INCA-IP is a CMOS device and operates with 1.8 V and 3.3 V supply voltages.
