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
155 *

303 *
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.

321 * If the array elements contain frequency parameters the driver will
322 * initialize the needed tone table elements and begin playing the tone,

324 * there is more than one frequency used in the cadence, sequential elements
