Abstract
It is desirable to be able to recognize data calls so that different charges can be applied to such calls and that vertical services, such as the use of special transmission facilities, may be offered to data callers. This recognition is accomplished by attaching a tone detector to a call in order to detect the special tones characteristic of a data call. Advantageously, this permits different charges to be imposed on data calls.
