%sev

• Returns the sub-event number (in decimal format) of the event being processed.

Sub-event = 255 is a "wild card", and the main event will be triggered on all sub-event numbers.

Some EventHandler reports use sub event in addition to the main event type:

• When used with feature 105, 'Event trigger on dialling digits', %SEV will return the dialled digit (Main event is Event Trigger with parameter (Event Type)).
• When used with External_Data_Input, %SEV is the EDIO port 1 - 10 the EDI text arrived on.
• When used with event 29 - AlphaNet Link, %SEV is the remote node number
• When used with event 33 - Private Ringing Outgoing, %SEV returns a number indicating the reason why ringing ended
