ATS10?

<value>

OK

This command sets the duration of received-line-signal loss that the DCE tolerates. If the duration is
exceeded, the DCE disconnects.

The duration setting is not persistent. As a result, it is not saved after a power cycle.

1-254 (default is 14)

Disconnect after number of tenths of seconds of received line-signal loss, e.g. for a
value of

14

1.4

seconds of received line-signal loss.

255

Ignore received line-signal loss, do not disconnect.

This command sets the DTMF pulse width (milliseconds) for both burst and continuous DTMF.

Burst DTMF (CDMA mode)

For burst DTMF, refer to section 2.7.2.3.2.7 Send Burst DTMF Message, TIA/EIA/IS-2000-5. The “Digit Time
Index” is the code that is transmitted in the Send Burst DTMF message to activate the DTMF generator at the
base station. The content of register S11 is used to determine the “Digit Time Index” to be used. Further, the
calculated “Digit Time Index” is used to determine the inter-digit time.

Digit Time Index

150 100

010 200..249

200 150

011 250

250 200

Continuous DTMF (CDMA mode)

For continuous DTMF, refer to section 2.7.3 Order Messages, TIA/EIA/IS-2000-5. The pulse width is
determined by the module via separate DTMF start and stop messages. A “Continuous DTMF Tone Order
(start)” message embedded with the tone code is sent to the base station to trigger the start of a DTMF tone.
A “Continuous DTMF Tone Order (stop)” message is sent to the base station to end the current tone
transmission. The continuous DTMF pulse width is calculated as follows:

S11 Value

DTMF Digit pulse width (ms)

251-255

( S11_Value – 250 ) X 1000

Note:

For continuous DTMF, only the first character in an ATD over-dial string (see 4.4.1.3 for ATD

Command reference) is transmitted. Any remaining characters are ignored.

DTMF (Analog mode)
