See above.
After deactivating bchannel, and if not used, the bchannel becomes idle again.
-Also the bchannel may be exported, but only if the state is or becomes idle:
-
-- B_STATE_EXPORTING
-The bchannel assignment has been sent to the remove application.
-
-- B_STATE_REMOTE
-The bchannel assignment is acknowledged by the remote application.
-
-- B_STATE_IMPORTING
-The bchannel is re-imported by mISDN port object.
-
-- B_STATE_IDLE
-See above.
-After re-importing bchannel, and if not used, the bchannel becomes idle again.
-
-
A bchannel can have the following events:
- B_EVENT_USE
- B_EVENT_DEACTIVATED
The bchannel becomes inactive.
-- B_EVENT_EXPORTED
-The bchannel is now used by remote application.
-
-- B_EVENT_IMPORTED
-The bchannel is not used by remote application.
-
-- B_EVENT_EXPORTREQUEST
-The bchannel shall be exported to the remote application.
-
-- B_EVENT_IMPORTREQUEST
-The bchannel is released from the remote application.
-
All actions taken on these events depend on the current bchannel's state and if it is linked to a Port class.
-if an export request is receive by remote application, p_m_remote_* is set.
-the b_remote_*[index] indicates if and where the channel is exported to. (set from the point on, where export is initiated, until imported is acknowledged.)
-- set on export request from remote application (if port is assigned)
-- set on channel use, if requested by remote application (p_m_remote_*)
-- cleared on drop request
-
-the bchannel will be exported with ref and stack given. remote application uses the ref to link bchannel to the call.
-the bchannel will be imported with stack given only. remote application must store stack id with the bchannel process.
-the bchannel import/export is acknowledged with stack given.
-
-if exporting, b_remote_*[index] is set to the remote socket id.
-if importing has been acknowledged. b_remote_*[index] is cleared.
