Add Channel-Associated Signalling (CAS) support
CAS frames are sent and received repeatedly. They consist of 16 frames (octets) on time slot 16. This is a CAS multi frame. This multiframe carries 30 individual CAS signaling channels.
Whenever a CAS frame is received, the included 30 CAS channels are forwarded to the application with a message of 30 octets, one octet for each CAS channel.
The application requests to transmit a CAS frame by sending a message with 30 octets, one for each CAS channel. Most recent CAS frame will be transmitted repeatedly until the application sends a new message.
The 30 octets in the message correspond to the signaling channels of these 30 time slots: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31
The lower 4 bits of each octet in the message represent the signaling sub-channels: A, B, C and D. They are packed like this: '0000ABCD'
