bchannel procedure
|
|
|
|
------------------
|
|
|
|
|
|
|
|
A bchannel goes through the following states in this order:
|
|
|
|
|
|
|
|
- B_STATE_IDLE
|
|
|
|
No one is using the bchannel.
|
|
|
|
It is available and not linked to Port class, nor reserved.
|
|
|
|
|
|
|
|
- B_STATE_ACTIVATING
|
|
|
|
The bchannel stack is created and an activation request is sent.
|
|
|
|
It MAY be linked to Port class, but already unlinked due to Port class removal.
|
|
|
|
|
|
|
|
- B_STATE_ACTIVE
|
|
|
|
The bchannel is active and cofigured to the Port class needs.
|
|
|
|
Also it is linked to a Port class, otherwhise it would be deactivated.
|
|
|
|
|
|
|
|
- B_STATE_DEACTIVATING
|
|
|
|
The bchannel is in deactivating state, due to deactivation request.
|
|
|
|
It may be linked to a Port class, that likes to reactivate it.
|
|
|
|
|
|
|
|
- B_STATE_IDLE
|
|
|
|
See above.
|
|
|
|
After deactivating bchannel, and if not used, the bchannel becomes idle again.
|
|
|
|
|
2007-08-11 13:57:58 +00:00
|
|
|
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.
|
|
|
|
|
2007-06-27 06:23:50 +00:00
|
|
|
|
|
|
|
A bchannel can have the following events:
|
|
|
|
|
2007-08-11 13:57:58 +00:00
|
|
|
- B_EVENT_USE
|
2007-06-27 06:23:50 +00:00
|
|
|
A bchannel is required by a Port class.
|
|
|
|
|
|
|
|
- B_EVENT_ACTIVATED
|
|
|
|
The bchannel beomes active.
|
|
|
|
|
2007-08-11 13:57:58 +00:00
|
|
|
- B_EVENT_DROP
|
2007-06-27 06:23:50 +00:00
|
|
|
The bchannel is not required by Port class anymore
|
|
|
|
|
|
|
|
- B_EVENT_DEACTIVATED
|
|
|
|
The bchannel becomes inactive.
|
|
|
|
|
2007-08-11 13:57:58 +00:00
|
|
|
- B_EVENT_EXPORTED
|
|
|
|
The bchannel is now used by remote application.
|
|
|
|
|
|
|
|
- B_EVENT_IMPORTED
|
|
|
|
The bchannel is not used by remote application.
|
|
|
|
|
2008-06-01 16:52:10 +00:00
|
|
|
- B_EVENT_EXPORTREQUEST
|
|
|
|
The bchannel shall be exported to the remote application.
|
|
|
|
|
|
|
|
- B_EVENT_IMPORTREQUEST
|
|
|
|
The bchannel is released from the remote application.
|
|
|
|
|
2007-06-27 06:23:50 +00:00
|
|
|
All actions taken on these events depend on the current bchannel's state and if it is linked to a Port class.
|
|
|
|
|
2007-08-13 21:29:09 +00:00
|
|
|
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.)
|
2007-08-12 08:16:19 +00:00
|
|
|
- set on export request from remote application (if port is assigned)
|
2007-08-13 21:29:09 +00:00
|
|
|
- set on channel use, if requested by remote application (p_m_remote_*)
|
2007-08-12 08:16:19 +00:00
|
|
|
- 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.
|
|
|
|
|
2007-08-13 21:29:09 +00:00
|
|
|
if exporting, b_remote_*[index] is set to the remote socket id.
|
|
|
|
if importing has been acknowledged. b_remote_*[index] is cleared.

audio transmission procedure:
|
|
|
|
-----------------------------
|
|
|
|
|
|
|
|
* priority
|
|
|
|
three sources of audio transmission:
|
|
|
|
- crypto-data high priority
|
|
|
|
- tones high priority (also high)
|
|
|
|
- remote-data low priority
|
|
|
|
|
|
|
|
* elapsed
|
|
|
|
a variable that temporarily shows the number of samples elapsed since last transmission process.
|
|
|
|
p_m_last_tv_* is used to store that last timestamp. this is used to calculate the time elapsed.
|
|
|
|
|
|
|
|
* load
|
|
|
|
a variable that is increased whenever data is transmitted.
|
|
|
|
it is decreased while time elapses. it stores the number of samples that
|
|
|
|
are currently loaded to dsp module.
|
|
|
|
since clock in dsp module is the same clock for user space process, these
|
|
|
|
times have no skew.
|
|
|
|
|
|
|
|
* levels
|
|
|
|
there are two levels:
|
|
|
|
ISDN_LOAD will give the load that have to be kept in dsp.
|
|
|
|
ISDN_MAXLOAD will give the maximum load before dropping.
|
|
|
|
|
|
|
|
* procedure for low priority data
|
|
|
|
see txfromup() for procedure
|
|
|
|
in short: remote data is ignored during high priority tones
|
|
|
|
|
|
|
|
* procedure for high priority data
|
|
|
|
whenever load is below ISDN_LOAD, load is filled up to ISDN_LOAD
|
|
|
|
if no more data is available, load becomes empty again.
|
|
|
|
|
|
|
|
'load' variable:
|
|
|
|
0 ISDN_LOAD ISDN_MAXLOAD
|
|
|
|
+--------------------+----------------------+
|
|
|
|
| | |
|
|
|
|
+--------------------+----------------------+
|
|
|
|
|
|
|
|
on empty load or on load below ISDN_LOAD, the load is inceased to ISDN_LOAD:
|
|
|
|
0 ISDN_LOAD ISDN_MAXLOAD
|
|
|
|
+--------------------+----------------------+
|
|
|
|
|TTTTTTTTTTTTTTTTTTTT| |
|
|
|
|
+--------------------+----------------------+
|
|
|
|
|
|
|
|
on empty load, remote-audio causes the load with the remote audio to be increased to ISDN_LOAD.
|
|
|
|
0 ISDN_LOAD ISDN_MAXLOAD
|
