Summary

The Microchip data modem library is composed of ITU-T compliant

algorithms for V.21, V.22, V.22bis, V.23, V.32 and V.32bis modem

recommendations. Bell standard 103 is also included in this library.

V.21, V.23 and Bell 103 are Frequency Shift Keying (FSK) modems. V.32,

V.32bis and V.22bis are Quadrature Amplitude Modulated (QAM)

modems. V.22 is a Quadrature Phase Shift Keyed (QPSK) modem. V.21,

V.22, V.22bis, V.32 and V.32bis are all 2-wire, Full Duplex modems. V.23

is Full-Duplex when it operates with a 75 bps backwards channel.

V.22bis includes fallback to V.22, V.23 and V.21 standards. V.32bis

optionally falls back to V.22bis, V.22, V.23 and V.21 standards.

Typical Applications

The dsPIC Soft Modem is well suited for small transaction orientated

based applications such as, but not limited to:

Features and Performance of Data Modems

Notes:

1. Data pump modules, V.21, V.22, V.22bis, V.23, V.32, V.32bis and Bell 103 are implemented in Assembly language. V.42, Data Pump and AT Command APIs are

2. The program/data memory usage for the V-series data pumps is NOT cumulative, due to the sharing of components internally.

3. Memory size does not account for application which combines data pump, V.42 and AT commands (if required).

4. V.21/Bell 103 and V.23 data pumps do not require V.42.

Contents

The data modem library is provided in two basic software packages:

The library currently supports single channel data-pump

implementations.

Both libraries are supported with fallback data pump modulations

down to V.21. Each data modem library is provided with a respective

library archive containing all the data pump object code modules

required to link to the user's application. Hardware component

drivers, such as UART and Data Converter Interface for DAA/AFE I/O

are provided in assembly source code for linking with the user's

application.

ITU-T Recommendation V.42 is provided with each library. V.42

contains a High Level Data Link Control (HDLC) protocol referred to as

Link Access Procedure for Modems (LAPM) and defines error-

correcting protocols for modems.

All data pump modulations are developed in ASM30 assembly code

yielding optimal code size and execution time. The AT, V.42 and Data

Pump APIs are based on C30 C language.

Electronic documentation accompanies the modem library to help you

become familiar with and implement the library functions. A

comprehensive Soft Modem User's Guide describes the required APIs

for the AT, V.42 and Data Pump layers.

V.22bis/V.22, which is offered free with full source code,

includes the following components:

–

V.32bis/V.32, which is offered in object code, includes the

following components:
