LINETERMMODE_ Constants

The LINETERMMODE_ bit-flag constants describe different types of events on a phone line that can be routed to a terminal device.

LINETERMMODE_BUTTONS

These are button-press events sent from the terminal to the line.

LINETERMMODE_LAMPS

These are lamp events sent from the line to the terminal.

LINETERMMODE_DISPLAY

This is display information sent from the line to the terminal.

LINETERMMODE_RINGER

This is ringer-control information sent from the switch to the terminal.

LINETERMMODE_HOOKSWITCH

These are hookswitch events sent from the terminal to the line.

LINETERMMODE_MEDIATOLINE

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_MEDIAFROMLINE

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_MEDIABIDIRECT

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.

No extensibility. 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).
