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_ACTIVATE
+- B_EVENT_USE
A bchannel is required by a Port class.
+The bchannel shall be exported to the remote application.
- B_EVENT_ACTIVATED
The bchannel beomes active.
-- B_EVENT_DEACTIVATE
+- B_EVENT_DROP
The bchannel is not required by Port class anymore
- 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.
+
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.
