  76 * This group of IOCTLs deal with the record settings of the DSP
  77 *
  78 * The IXJCTL_REC_DEPTH command sets the internal buffer depth of the DSP.
  79 * Setting a lower depth reduces latency, but increases the demand of the
  80 * application to service the driver without frame loss.  The DSP has 480
  81 * bytes of physical buffer memory for the record channel so the true
  82 * maximum limit is determined by how many frames will fit in the buffer.
  83 *
  84 * 1 uncompressed (480 byte) 16-bit linear frame.
  85 * 2 uncompressed (240 byte) 8-bit A-law/mu-law frames.
  86 * 15 TrueSpeech 8.5 frames.
  87 * 20 TrueSpeech 6.3,5.3,4.8 or 4.1 frames.
  88 *
  89 * The default in the driver is currently set to 2 frames.
  90 *
  91 * The IXJCTL_REC_VOLUME and IXJCTL_PLAY_VOLUME commands both use a Q8
  92 * number as a parameter, 0x100 scales the signal by 1.0, 0x200 scales the
  93 * signal by 2.0, 0x80 scales the signal by 0.5.  No protection is given
  94 * against over-scaling, if the multiplication factor times the input
  95 * signal exceeds 16 bits, overflow distortion will occur.  The default
  96 * setting is 0x100 (1.0).
  97 *
  98 * The IXJCTL_REC_LEVEL returns the average signal level (not r.m.s.) on
  99 * the most recently recorded frame as a 16 bit value.

 153 *    Ring Back   - 26
 154 *    Busy Signal - 27

 304 * The IXJCTL_TONE_CADENCE ioctl defines tone sequences used for various
 305 * Call Progress Tones (CPT).  This is accomplished by setting up an array of
 306 * IXJ_CADENCE_ELEMENT structures that sequentially define the states of
 307 * the tone sequence.  The tone_on_time and tone_off time are in
 308 * 250 microsecond intervals.  A pointer to this array is passed to the
 309 * driver as the ce element of an IXJ_CADENCE structure.  The elements_used
 310 * must be set to the number of IXJ_CADENCE_ELEMENTS in the array.  The
 311 * termination variable defines what to do at the end of a cadence, the
 312 * options are to play the cadence once and stop, to repeat the last
 313 * element of the cadence indefinitely, or to repeat the entire cadence
 314 * indefinitely.  The ce variable is a pointer to the array of IXJ_TONE
 315 * structures.  If the freq0 variable is non-zero, the tone table contents
 316 * for the tone_index are updated to the frequencies and gains defined.  It
 317 * should be noted that DTMF tones cannot be reassigned, so if DTMF tone
 318 * table indexes are used in a cadence the frequency and gain variables will
 319 * be ignored.
 320 *
 321 * If the array elements contain frequency parameters the driver will
 322 * initialize the needed tone table elements and begin playing the tone,
 323 * there is no preset limit on the number of elements in the cadence.  If
 324 * there is more than one frequency used in the cadence, sequential elements
 325 * of different frequencies MUST use different tone table indexes.  Only one
 326 * cadence can be played at a time.  It is possible to build complex
 327 * cadences with multiple frequencies using 2 tone table indexes by
 328 * alternating between them.
