This Recommendation defines two packages that provide enhanced alerting and data transfer capabilities for [ITU-T H.248.1]. The support of these packages is optional. There is a direct mapping between the alert i pattern parameter@ alert/cw pattern parameter@ and to the andisp/dwa pattern parameter. Ringing patterns and call waiting patterns are paired to allow for distinctive alerting sets. In expanding this parameter in the future@ it would be desirable to expand the alert i@ alert/cw@ and andisp/dwa signals together@ maintaining the distinctive pattern pairings. This will continue to allow the andisp/dwa signal to have a definition independent of the alerting method@ linking it only to the alerting style (pattern).
