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.
