These bit-flag constants describe different types of events on a phone line that can be routed to a terminal device.
The following table shows the LINETERMMODE constants.
| Value | Description |
|---|---|
|
LINETERMMODE_BUTTONS = 0x00000001 |
These are button-press events sent from the terminal to the line. |
|
LINETERMMODE_DISPLAY = 0x00000004 |
This is display information sent from the line to the terminal. |
|
LINETERMMODE_HOOKSWITCH = 0x00000010 |
These are hookswitch events sent from the terminal to the line. |
|
LINETERMMODE_LAMPS = 0x00000002 |
These are lamp events sent from the line to the terminal. |
|
LINETERMMODE_MEDIABIDIRECT = 0x00000080 |
This is the bidirectional media stream associated with a call on the line and the terminal. Use this value when the routing of both unidirectional channels of a call's media stream cannot be controlled independently. |
|
LINETERMMODE_MEDIAFROMLINE = 0x00000040 |
This is the unidirectional media stream from the line to the terminal associated with a call on the line. Use this value when the routing of both unidirectional channels of a call's media stream can be controlled independently. |
|
LINETERMMODE_MEDIATOLINE = 0x00000020 |
This is the unidirectional media stream from the terminal to the line associated with a call on the line. Use this value when the routing of both unidirectional channels of a call's media stream can be controlled independently. |
|
LINETERMMODE_RINGER = 0x00000008 |
This is ringer-control information sent from the switch to the terminal. |
Remarks
These constants cannot be extended. All 32 bits are reserved.
These constants describe the classes of control and information streams that can be routed directly between a line device and a terminal device such as a phone set.
