Functional Description
Host Interface
© 2005 Copeland Communications, Inc.
The World modem™ NET is a complete embedded modem with integrated direct access arrangement (DAA)
that provides a programmable line interface to meet global telephone line requirements. This solution includes
a DSP data pump, modem controller, on-chip RAM and ROM, codec, DAA and analog output. The World
Modem™ NET accepts standard modem AT commands and provides connect rates up to 56/33.6/14.4 kbps
full-duplex over the Public Switched Telephone Network (PSTN). The World modem™ NET features a
complete set of modem protocols including all ITU-T standard formats up to 56 kbps. The World modem™
NET provides numerous additional features for embedded modem applications. The modem includes full type I
and type II caller ID detection and decoding for global standards. Call progress is supported through echoing
result codes and is also programmable to meet global settings. Because the World modem™ NET integrates
the DAA, analog features, such as parallel phone detect, overcurrent detection, and global PTT compliance
with a single design, are included. This device is ideal for embedded modem applications due to its small
board space, low power consumption, and global compliance. The silicon DAA can be programmed to meet
worldwide PTT specifications for ac termination, dc termination, ringer impedance, and ringer threshold. In
addition, the World modem™ NET has been designed to meet the most stringent worldwide requirements for
out-of-band energy, billing-tone immunity, surge immunity, and safety requirements. The World modem™
NET allows for rapid integration into existing modem applications by providing a serial interface that can
directly communicate to either a microcontroller via a UART interface or a PC via an RS-232. This interface
allows for PC evaluation of the modem immediately upon power-up via the AT commands using standard
terminal software.
Following is a list of supported protocols:
The host interface is serial TTL. The World Modem™ NET defaults to autobaud on reset and 8N1 format (8
data bits, no parity bit and 1 stop bit). The defaults can be changes after initialization by using standard AT
commands. A true RS-232 interface is available on the World modem Evaluation Board.
