Serial asynchronous automatic dialling and control |
 |
This Recommendation defines commands and responses for use by a DTE to control a V-series DCE using serial data interchange over an asynchronous interface. It contains four elements:
– codifies existing practice in common GSTN-DCE that use the ATtention (AT) command set;
– defines a format for orderly extension of the AT command set;
– provides a set of standardized extensions for common functions to identify the DCE, to control the DTE-DCE interface, and to control DCE-DCE protocols (signal conversion, error control and data compression);
– provides a mapping for these commands into V.25 bis frame format for use with DCEs employing synchronous serial interfaces.
