| void H323_T120Channel::Receive | ( | ) | [virtual] |
Handle channel data reception.
This is called by the thread started by the Start() function and is typically a loop reading from the transport and handling PDU's.
The default behaviour here is to call HandleChannel()
Implements H323Channel.

References HandleChannel().
| void H323_T120Channel::Transmit | ( | ) | [virtual] |
Handle channel data transmission.
This is called by the thread started by the Start() function and is typically a loop reading from the codec and writing to the transport (eg an RTP_session).
The default behaviour here is to call HandleChannel()
Implements H323Channel.

| BOOL H323_T120Channel::OnSendingPDU | ( | H245_OpenLogicalChannel & | openPDU | ) | const [virtual] |
Fill out the OpenLogicalChannel PDU for the particular channel type.
| openPDU | Open PDU to send. |

| void H323_T120Channel::OnSendOpenAck | ( | const H245_OpenLogicalChannel & | open, | |
| H245_OpenLogicalChannelAck & | ack | |||

This is called when request to create a channel is received from a remote machine and is about to be acknowledged.
| open | Open PDU |
| ack | Acknowledgement PDU |

| BOOL H323_T120Channel::OnReceivedPDU | ( | const H245_OpenLogicalChannel & | pdu, | |
| unsigned & | errorCode | |||
| ) | [virtual] |
This is called after a request to create a channel occurs from the local machine via the H245LogicalChannelDict::Open() function, and the request has been acknowledged by the remote endpoint.
The default makes sure the parameters are compatible and passes on the PDU to the rtp session.
| pdu | Open PDU |
| errorCode | Error code on failure |
