SC14CVMDECT SF

Cordless Voice Module

FINAL

2.0 Introduction

2.1 SCOPE

The SC14CVMDECT SF is a programmable DECT

module for voice and data services. The internal soft-

ware stack receives commands and data from the

application, for instance to set up a link to other mod-

ules. The application software can be implemented on

the module itself or on an external host processor. The

internal FLASH provides user space where custom

applications can be located.

The module converts analog signals to a digital stream,

compresses/decompresses them according to the

DECT standards and transmits/receives them over the

air interface. The DECT protocol stack in each module

supports both PP and FP functionality.

The embedded software running on the internal micro-

controller (CR16) supports all protocol layers up to the

network layer. The module can be controlled by soft-

ware running on the internal controller as well as from

an external controller via the UART.
