Par # | Parameter Description |
|
| Range | Reference |
31 | TAD receive gain |
| — | ||
32 | Half/full wave ring detection | 0 | = halfwave, 1 = fullwave | — | |
33 | Number of failed attempts allowed in first stage |
| ATD | ||
| delayed dialing |
|
|
|
|
34 | Number of all failed attempts ( to any number) |
| ATD | ||
| allowed before any further dial attempts are blocked | 255 = not applicable |
|
| |
35 | Erroneous call increment count |
| ATD | ||
36 | Dial tone validation time in multiples of 100 ms |
| ATD | ||
37 | Busy tone detection during dial tone detection flag | 0 | = not required, 1 = required | ATD | |
38 | DTMF high and low tone level difference in dB |
| — | ||
39 | Local phone detection in speakerphone | 0 | = enabled; 1 = disabled | — | |
3a | Pulse dialing flag | 0 | = enabled; 1 = disabled | ATD | |
3b | Dial tone/call progress filter index | 0 | = | 1 = | — |
|
| 2 | = | 3 = |
|

|
3c | Dial tone detection threshold in dB |
| — | ||
3d | ABCD dialing permitted flag | 0 | = permitted, 1 = not permitted | ATD | |
3e | Comma pause duration limit in seconds. (If there are |
| ATD | ||
| multiple commas between digits, the total pause |
|
|
|
|
| duration is limited to the duration set by this |
|
|
|
|
| parameter). |
|
|
|
|
3f | TAD transmit level in dB |
| — | ||
40 | Data/FAX carrier receive threshold in dB. There is a 6 |
| — | ||
| dB offset in DSP. This parameter value should set to: |
|
|
|
|
| (required threshold [6 dB] DAA gain) |
|
|
|
|
41 | No dialtone |
| ATD | ||
| with W dial modifier, in seconds |
|
|
|
|
42 | FAX/Data answer tone detection threshold in dB |
| — | ||
43 | Dialtone level (absolute value) |
| — | ||
44 | FAX receive threshold in dB |
| — | ||
45 | Pulse and tone dial in same dial string permitted flag | 0 | = permitted, 1 = not permitted | ATD | |
46 | Ringer impedance relay flag | 0 | = off, 1 = on |
|
|
47 | DC loop V/I characteristics relay flag | 0 | = off, 1 = on |
|
|
48 | DC loop limiting relay flag | 0 | = off, 1 = on |
|
|
49 | Real/complex impedance | 0x0X = real, Tx & Rx gains set by mercury |
| ||
|
| internal components. X = Don’t care |
| ||
|
| 0x10 = real, Tx gain set by mercury |
| ||
|
| internal components & Rx gain set by |
| ||
|
| external components. |
| ||
|
| 0x12 = complex, Tx gain set by mercury |
| ||
|
| internal components & Rx gain set by |
| ||
|
| external components. Mercury internal |
| ||
|
| switch used to select complex impedance. |
| ||
4a | Mercury register CIOCA MSB | This parameter is relevant only when a Mercury | — | ||
|
| line codec is used. |
