Multi-Tech Systems ISIHP-4S manual S10 Carrier Loss Disconnect Delay Time, S35 Data Calling Tone

Modem AT Commands & S-Registers

S10 Carrier Loss Disconnect Delay Time

Unit: 100 ms

Range: 1–254

Default: 20

Defines the length of time, in milliseconds, that the modem waits after a loss of carrier signal before the it disconnects. The default setting is 2000 ms (20 units of 100 ms each). Maximum delay is 25400 milliseconds, or 25.4 seconds (decimal 254).

S11 Tone Dialing Spacing and Duration

Unit: 1 ms

Range: 50 - 150 (US) or 80–255 (Canada, UK, International)

Default: 95 (US) or 80 (Canada, UK, International)

Sets the speed of tone dialing (spacing and tone duration times). The default value is 95 units for domestic models and 80 units for Canadian and International models, where each unit is one ms. In other words, for domestic modems, each tone is sustained for 95 ms followed by a 95 ms pause. The minimum S11 value allowed is 50 ms (50 units). The maximum S11 value is 150 ms (150 units).

S28 Enable / Disable V.34 Modulation

Unit: decimal

Range: 0, 1–255 Default:1 (enabled)

Enables or disables V.34 modulation. Setting S28 to zero (0) disables V.34 modulation. Any other setting (1-255) enables V.34 modulation.

S35 Data Calling Tone

Unit: decimal

Range: 0–1

Default: 0 (disabled)

Enables or disables the V.25 data calling tone, which allows remote data, fax and voice discrimination. Setting S35 to zero (0) disables V.25 data calling tone; setting S35 to 1 enables data calling tone. The default setting is 1.
