Legend:

This table lists events without any regard as to whether the DCE reporting of the event
is optional or mandatory, and without assigning a DCE reporting mechanism.
The first column lists the event number assignment for each event. The event number
also serves another purpose; each number is a bit position in a bit field. Event number
0 is the most significant bit of the left most hex number in a hex representation (V.253
defines a total of eight hex digits). The final bit in the bit field occupies the least
significant bit position of the right-most hex number. The bit representations of the
event numbers are used in the +VLS= command.
The third column lists whether a single character is enough to report the event, or if the
DCE must supply a more complicated report. The description Simple indicates a single
character response (<DLE> shielded), Message indicates a full text message
(<DLE><X> packet), and Pattern indicates a repeating Message.

Notes:

1. The use of complex event reporting for Stuttered Dial tone is for further study.
