*
* This group of IOCTLs deal with the record settings of the DSP
*
* The IXJCTL_REC_DEPTH command sets the internal buffer depth of the DSP.
* Setting a lower depth reduces latency, but increases the demand of the
* application to service the driver without frame loss.  The DSP has 480
* bytes of physical buffer memory for the record channel so the true
* maximum limit is determined by how many frames will fit in the buffer.
*
* 1 uncompressed (480 byte) 16-bit linear frame.
* 2 uncompressed (240 byte) 8-bit A-law/mu-law frames.
* 15 TrueSpeech 8.5 frames.
* 20 TrueSpeech 6.3,5.3,4.8 or 4.1 frames.
*
* The default in the driver is currently set to 2 frames.
*
* The IXJCTL_REC_VOLUME and IXJCTL_PLAY_VOLUME commands both use a Q8
* number as a parameter, 0x100 scales the signal by 1.0, 0x200 scales the
* signal by 2.0, 0x80 scales the signal by 0.5.  No protection is given
* against over-scaling, if the multiplication factor times the input
* signal exceeds 16 bits, overflow distortion will occur.  The default
* setting is 0x100 (1.0).
*
* The IXJCTL_REC_LEVEL returns the average signal level (not r.m.s.) on
* the most recently recorded frame as a 16 bit value.

* This IOCTL allows you to reassign values in the tone index table.  The
* tone table has 32 entries (0 - 31), but the driver only allows entries
* 13 - 27 to be modified, entry 0 is reserved for silence and 1 - 12 are
* the standard DTMF digits and 28 - 31 are the DTMF tones for A, B, C & D.
* The positions used internally for Call Progress Tones are as follows:
*    Dial Tone   - 25
*    Ring Back   - 26
*    Busy Signal - 27
*
* The freq values are calculated as:
* freq = cos(2 * PI * frequency / 8000)
*
* The most commonly needed values are already calculated and listed in the
* enum IXJ_TONE_FREQ.  Each tone index can have two frequencies with
* different gains, if you are only using a single frequency set the unused
* one to 0.
*
* The gain values range from 0 to 15 indicating +6dB to -24dB in 2dB
* increments.

/******************************************************************************
*
* The IXJCTL_TONE_CADENCE ioctl defines tone sequences used for various
* Call Progress Tones (CPT).  This is accomplished by setting up an array of
* IXJ_CADENCE_ELEMENT structures that sequentially define the states of
* the tone sequence.  The tone_on_time and tone_off time are in
* 250 microsecond intervals.  A pointer to this array is passed to the
* driver as the ce element of an IXJ_CADENCE structure.  The elements_used
* must be set to the number of IXJ_CADENCE_ELEMENTS in the array.  The
* termination variable defines what to do at the end of a cadence, the
* options are to play the cadence once and stop, to repeat the last
* element of the cadence indefinitely, or to repeat the entire cadence
* indefinitely.  The ce variable is a pointer to the array of IXJ_TONE
* structures.  If the freq0 variable is non-zero, the tone table contents
* for the tone_index are updated to the frequencies and gains defined.  It
* should be noted that DTMF tones cannot be reassigned, so if DTMF tone
* table indexes are used in a cadence the frequency and gain variables will
* be ignored.
*
* If the array elements contain frequency parameters the driver will
* initialize the needed tone table elements and begin playing the tone,
* there is no preset limit on the number of elements in the cadence.  If
* there is more than one frequency used in the cadence, sequential elements
* of different frequencies MUST use different tone table indexes.  Only one
* cadence can be played at a time.  It is possible to build complex
* cadences with multiple frequencies using 2 tone table indexes by
* alternating between them.
