Brief Description
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. It puts all the main data processing elements in one device, no ISDN software has to be written and simple ‘Plug and Play’ design results. The CMX218 supports one voice port, which can be used to provide ISDN telephony services or a POTS line interface, and one data channel, capable of operation at 115,200 b/s. It also has a full set of ‘Hayes’ compatible AT command codes on its asynchronous data interface and keypad-configurable voice telephony services.
