Description
ISDN data and telephony protocol engine
Manufacturer
MX-COM, Inc.
Datasheet
Features
The CMX218 is an ISDN data and telephony protocol engine which implements the lower level ISDN interface
and communicates with the CMX605 and other standard devices to form a fully integrated ISDN chipset for
both voice and data communications. The CMX218 puts all the main data processing elements in a single
device. No ISDN software has to be written and simple ‘Plug and Play’ design results. This reduces
development time and provides a highly cost-effective hardware solution. By using proven circuit designs, the
designer can move quickly from initial concept through design in to manufacture.
The CMX218 supports one voice port over the ISDN Line, which can be used to provide ISDN telephony
services or a POTS line interface, and a single data channel, capable of operation at 115,200 bps. The
CMX218 features a full set of ‘Hayes’ compatible AT command codes on its asynchronous data interface, in
addition to providing keypad-configurable voice telephony services. The CMX218’s feature set and
architecture allow most analog systems to be converted to an ISDN equivalent with enhanced features.
The CMX218 is designed to work with the AMD 79C30 S/T bus interface, the Siemens PSB-21525 HDLC
formatter and the MX-COM CMX605 POTS interface circuit, and also comes complete with embedded
applications software. To support the CMX218, MX-COM can also provide licensed reference designs on
user request. A flexible Applications Program Interface (API) allows users to customize the features and
operation of their own design. The CMX218 is available in an 80-pin QFP (CMX218S1) package.
1 The CMX218 is a data processor integrated circuit that supports the protocol layers 1, 2 and 3 of the ISDN protocol stack in accordance
with the specifications of CCITT (now ITU). These specifications, which are widely used around the world, might not be supported within
the U.S.
