S91 - PSTN Transmit Attenuation Level
In non-PCM modes (V.90 or K56flex are PCM modes), S91 sets the transmit
attenuation level from 0 to 15 dBm for the PSTN mode, resulting in a transmit
level from 0 to –15 dBm. In some countries, the transmit level may not be changed
and there are checks to prevent transmit attenuation level change using
ConfigurACE.
Range: 0 to 15 dBm (Corresponding to 0 to -15 dBm transmit level.)
Default: 10 (-10 dBm transmit level.)
S92 - Fax Transmit Attenuation Level
S92 sets the transmit attenuation level from 0 to 15 dBm for the fax mode,
resulting in a transmit level from 0 to -15 dBm. In some countries, the transmit
level may not be changed and there are checks to prevent transmit attenuation level
change using ConfigurACE.
Range: 0 to 15 dBm (Corresponding to 0 to -15 dBm transmit level.)
Default: 10 (-10 dBm transmit level.)
S95 - Extended Result Codes Control
A bit set to a 1 in this parameter, in conjunction with the W command, will enable
the corresponding extended result code (see Table A-6).
The +MR, +ER, and +DR settings also control S95, bits 2, 3, and 5, respectively.
The more recent settings of +MR, +ER, and +DR, or host writing of S95, bits 2,
3, and 5, along with the W command setting, determine the corresponding actual
result code reporting (see +MR, +ER, DR, and W commands).
Default: 0
Bit 0 CONNECT result code indicates DCE speed instead of DTE speed.
Bit 1 Append/ARQ to CONNECT XXXX result code in error-correction mode
(XXXX = rate).
Bit 2 MCR: XXXX result code (XXXX = modulation) and +MRR:
XXXX result code (XXXX = rate). (Also, see +MR.)
Bit 3 ER: XXXX result code (XXXX = protocol identifier).
Bit 4 Reserved.
Bit 5 DR: XXXX result code (XXXX = compression type).
Bits 6-7 Reserved.
