Functional Description
Host Interface
© 2004, Copeland Communications, Inc.
The World modem II 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 II 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 II features a complete set of
modem protocols including all ITU-T standard formats up to 56 kbps. The World modem II 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 II 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 II has been designed to meet the most stringent worldwide requirements for out-of-band energy,
billing-tone immunity, surge immunity, and safety requirements.
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.
The host interface is serial TTL. The default host speed of 19.2 Kb 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.
