S6 - Wait Time for Dial Tone Before Blind Dialing, or After “W” Dial Modifier (W-Class Models)
1. Sets the length of time, in seconds, that the modem will wait before starting to dial after going off-hook when blind
dialing. This operation, however, may be affected by some ATX options according to country restrictions. The “Wait for
Dial Tone” call progress feature (W dial modifier in the dial string) will override the value in register S6.
2. For W-class models, S6 sets the length of time, in seconds, that the modem will wait for dial tone when encountering a
“W” dial modifier before returning NO DIAL TONE result code.
The modem always pauses for a minimum of 2 seconds, even if the value of S6 is less than 2 seconds.
Range: 2-255 seconds
Default: 2
S7 - Wait Time For Carrier After Dial, For Silence, or For Dial Tone After “W” Dial Modifier (US Models)
1. Sets the length of time, in seconds, that the modem will wait for carrier before hanging up. The timer is started when
the modem finishes dialing (originate), or 2 seconds after going off-hook (answer). In originate mode, the timer is reset
upon detection of answer tone if allowed by country restrictions.
2. Sets the length of time, in seconds, that modem will wait for silence when encountering the @ dial modifier before
continuing with the next dial string parameter.
3. For US models, S7 sets the length of time, in seconds, that the modem will wait for dial tone when encountering a “W”
dial modifier before continuing with the next dial string parameter.
Range: 1-255 seconds
Default: 50
S8 - Pause Time For Dial Delay
Sets the time, in seconds, that the modem must pause when the “,” dial modifier is encountered in the dial string.
Range: 0-255 seconds
Default: 2
S9 - Carrier Detect Response Time
Sets the time, in tenths of a second, that the carrier must be present before the modem considers it valid and turns on
RLSD. As this time is increased, there is less chance to detect a false carrier due to noise from the telephone line.
Range: 1-255 tenths of a second
Default: 6 (0.6 second)
S10 - Lost Carrier To Hang Up Delay
Sets the length of time, in tenths of a second, that the modem waits before hanging up after a loss of carrier. This allows for
a temporary carrier loss without causing the local modem to disconnect. When register S10 is set to 255, the modem
functions as if a carrier is always present.
The actual interval the modem waits before disconnecting is the value in register S10 minus the value in register S9.
Therefore, the S10 value must be greater than the S9 value or else the modem disconnects before it recognizes the carrier.
Range: 1-255 tenths of a second
Default: 14 (1.4 seconds)
S11 - DTMF Tone Duration
Sets the duration of tones in DTMF dialing (US models only). This value has no effect on pulse dialing.
For W-class models, this parameter is a country parameter loaded by ConfigurACE.
Range: 50-255 milliseconds
Default: 95 (95 milliseconds)
