| command | equipment allows control end to send control command. |
| all | equipment allows above-mentioned all message, is equivalent to all-status, query, command. |
NOTIFY design
1.NOTIFY message sends status query request or operational order request to control end transmitting apparatus state and control end to equipment for equipment.
2.NOTIFY message must contain Event header field, and value must be line-status.Event is an additional specification, has wherein defined a series of state informations that sent to subscriber by informant, and Line-status has identified equipment state information.
3.NOTIFY message must contain Subscription-Stat header field, and value is active.This header field represents that current NOT IFY event is an effective state-event.
4.NOTIFY message must contain message body, must comprise Content-Type header field, and its value is text/plain.It is a kind of unformatted text that Content-Type instruction sends to recipient's type of message.
5.NOTIFY message must comprise Type header field, and Type indicates a kind of type of message body, and its value is one in query, status, command.Meanwhile, NOTIFY must comprise the header field of the same name with the value of Type header field.
If the header field that 6. NOTIFY comprises is Query, i.e. inquiry, its value must be line-status, call-status or all-status.The implication of its value is as follows:
| query | explanation |
| line-status | equipment state information notice; Equipment can be to control end transmitting apparatus level correlation behavior; |
| call-status | talking state message informing; Equipment can send talking stage correlation behavior to control end; |
| all-status | equipment can send all states to control end, is equivalent to line-status, call-status. |
If the header field that 7. NOTIFY comprises is Status, i.e. a kind of status information of equipment, its value is necessary for Open/Close or user-defined order.
If the header field that 8 NOTIFY comprise is command field, i.e. control end manipulation order, its value is necessary for Open/Close or user defined command.
