Description: Contains headers of a Q.921 protocol on top of the Comet
|
||||
Driver.
|
||||
|
||||
Most of the work required to execute a Q.921 protocol is
|
||||
taken care of by the Comet ship and it's driver. This layer
|
||||
will simply configure and make use of these features to
|
||||
complete a Q.921 implementation.
|
||||
|
||||
Note: This header file is the only include file that should be
|
||||
acessed by users of the Q.921 stack.
|
||||
|
||||
Interface: The Q.921 stack contains 2 layers.
|
||||
|
||||
- One interface layer.
|
||||
- One driver layer.
|
||||
|
||||
The interface layer contains the interface functions required
|
||||
for a layer 3 stack to be able to send and receive messages.
|
||||
|
||||
The driver layer will simply feed bytes into the ship as
|
||||
required and queue messages received out from the ship.
|
||||
|
||||
Q921TimeTick The Q.921 like any other blackbox
|
||||
modules contains no thread by it's own
|
||||
and must therefore be called regularly
|
||||
by an external 'thread' to do maintenance
|
||||
etc.
|
||||
|
||||
Q921Rx32 Receive message from layer 3. Called by
|
||||
the layer 3 stack to send a message.
|
||||
|
||||
Q921Tx23 Send a message to layer 3.
|
||||
|
||||
OnQ921Error Function called every if an error is
|
||||
deteceted.
|
||||
|
||||
OnQ921Log Function called if logging is active.
