AT Commands for Homologation Testing and Debugging (continued)
Table 13. The Homologation Parameters (continued)
Par # Parameter Description
31 TAD receive gain
32 Half/full wave ring detection
33 Number of failed attempts allowed in first stage
delayed dialing
34 Number of all failed attempts ( to any number)
allowed before any further dial attempts are blocked
35 Erroneous call increment count
36 Dial tone validation time in multiples of 100 ms
37 Busy tone detection during dial tone detection flag
38 DTMF high and low tone level difference in dB
39 Local phone detection in speakerphone
3a Pulse dialing flag
3b Dial tone/call progress filter index
3c Dial tone detection threshold in dB
3d ABCD dialing permitted flag
3e Comma pause duration limit in seconds. (If there are
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 time-out duration while detecting dialtone
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
46 Ringer impedance relay flag
47 DC loop V/I characteristics relay flag
48 DC loop limiting relay flag
49 Real/complex impedance
4a Mercury register CIOCA MSB value—receive gain

0 = off, 1 = on
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.
This parameter is relevant only when a Mercury
line codec is used.
