20 * There are 3 different solutions: -1 = software, 0 = hardware-crossconnect
21 * 1-n = hardware-conference. The n will give the conference number.
39 * - Crossconnecting or even conference, if more than two members are together.
40 * - Force mixing of transmit data with other crossconnect/conference members.
41 * - Echo generation to benchmark the delay of audio processing.
42 * - Use hardware to minimize cpu load, disable FIFO load and minimize delay.
43 * - Dejittering and clock generation.
48 * RX-Buffer
51 * ----------------+-------------+-------------------
53 * The rx-buffer is a ring buffer used to store the received data for each
56 * The transmit-clock (R) will read the buffer.
57 * If the clock overruns the write-pointer, we will have a buffer underrun.
58 * If the write pointer always has a certain distance from the transmit-
63 * TX-Buffer
66 * -----------------+--------+-----------------------
68 * The tx-buffer is a ring buffer to queue the transmit data from user space
82 * - has multiple clocks.
83 * - has no usable clock due to jitter or packet loss (VoIP).
89 * - If a member joins, its rx_buff is set to silence and change read pointer
103 * Changing rx-volume is done before the data is crossconnected. The tx-volume
108 * the card. It will replace the tx-data from the user space.
112 * Disable rx-data:
113 * If cmx is realized in hardware, rx data will be disabled if requested by
114 * the upper layer. If dtmf decoding is done by software and enabled, rx data
119 * used if not forbidden by control command. Disabling rx-data provides
120 * absolutely traffic free audio processing. (except for the quick 1-frame
