Functional Description
© 2007, Copeland Communications, Inc.
The CC-2401K2 is a complete modem with integrated DAA that provides a programmable line interface
meeting all global telephone line requirements. The modem accepts simple AT commands and provides
connect rates up to 2400 baud, full-duplex. The modem supports V.42 hardware support through HDLC
framing. To minimize handshake times, the CC-2401K2 can implement a V.22-based fast connect. V.23
reversing protocol and standard alarm formats including SIA are also supported.
The World Modem II family of products is ideal for embedded applications due to its small form factor, low
power consumption and global compliance. The CC-2401K2 contains everything necessary to connect to the
Public Switched Telephone Network (PTSN). All that is needed is a connector to the local phone line. No
external filtering or fusing are required.
The CC-2401K2 is designed for rapid design into existing modem applications. The modem interfaces directly
to a microcontroller’s UART. The CC-EVAL kit comes with full schematics to help design and a fully functional
board to connect to a PC serial port for rapid testing and evaluation.
The modem can be fully programmed to meet international telephone line interface requirements with full
compliance to FCC, TBR21, JATE and other country-specific PTT specifications. The CC-2401 is designed to
meet worldwide requirements for out-of-band energy, billing-tone immunity, high voltage surges, and safety
requirements.
*
(1200 bps only modem. Because the V.22bis specification does not outline a fallback procedure, the host should
implement a fallback mechanism consisting of hanging up and connecting at a lower baud rate. Retraining to
accommodate changes in line conditions that occur during a call must be implemented by terminating the call and
redialing.
NOTE: The CC-2401 only adjusts its DCE rate from 2400 bps to 1200 bps if it is connecting to a V.22-only
