Digi 90031300 manual S6 Wait Before Dialing, S7 Wait for Carrier, S9 Carrier Validation Time

S6 Wait Before Dialing

Sets the length of time, in seconds, that the modem must wait (pause) after going off-hook before dialing the first digit of the telephone number. The modem always pauses for a minimum of 2 s, even if the value of S6 is less than 2 s. The wait for dial tone call progress feature (W dial modifier in the dial string) will override the value in register S6. This operation, however, may be affected by some ATX options according to country restrictions.

Range: 2-255

Default: 002

Units: seconds

S7 Wait for Carrier

Sets the time, in seconds, that the modem must wait before hanging up because carrier is not detected. The timer is started when the modem finishes dialing (originate), or goes off-hook (answer). In originate mode, the timer is reset upon detection of answer tone if allowed by country restrictions. This timer also specifies the wait for silence time for the @ dial modifier in seconds. S7 is not associated with the W dial modifier.

Range: 1-255

Default: 060

Units: seconds

S8 Pause Time for Command or Dial Modifier

Sets the time, in seconds, that the modem must pause when the “,” dial modifier is encountered in the dial string.

Range: 0-255

Default: 002

Units: seconds

S9 Carrier Validation 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

Default: 006 (0.6 second)

Units: 0.1 s

S10 Lost Carrier 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

Default: 014 (1.4 s)

Units: 0.1 s

S11 DTMF Duration and Interdigit Delay

Range: 50-255

Default: 095 ms

Units: 0.001 s
