6.2.2.12 +VSM - Compression Method Selection

This command causes the modem to set the voice compression method, the silence compression sensitivity, and the voice

sampling rate.

Syntax

+VSM=<cml>,<vsr>,<sds>,<sel>

Defined Values

<cml> Decimal number identifying the compression method.

<vsr> <range of values> containing the supported range of voice samples per second of the analog

signal.

<scs> <range of values> containing the supported range of sensitivity settings for voice receives.

<sel> <range of values> containing the supported range of expansion values for voice transmits.

Reporting Current or Selected Values

Command: +VSM?

Response: <cml>,<vsr>,<sds>,<sel>

Example: 1,8000,0,0 Default

Reporting Supported Range of Parameter Values

Command: +VSM=?

Response: <cml>,<cmid>,<bps>,<tm>,<vsr>,<sds>,<sel>

<cml> Decimal number identifying the compression method (1, 129, 130, 140, or 141).

<cmid> Alphanumeric string describing the compression method (UNSIGNED PCM, IMA ADPCM,

UNSIGNED PCM, 2 Bit ADPCM, or 4 Bit ADPCM).

<bps> Decimal number defining the average number of bits in the compressed sample not including

silence compression (2, 4 or 8).

<tm> Decimal number (0) reporting the time interval, in units of 0.1 second, between timing marks. A

value of 0 reports that timing marks are not supported.

<vsr> <range of values> containing the supported range of voice samples per second of the analog

signal (8000).

<scs> <range of values> containing the supported range of sensitivity settings for voice receives (0). A 0

indicates not supported.

<sel> <range of values> containing the supported range of expansion values for voice transmits (0). A 0

indicates not supported.

Example: 1,"UNSIGNED PCM",8,0,8000,0,0

129,"IMA ADPCM",4,0,8000,0,0

130,"UNSIGNED PCM",8,0,8000,0,00

140,"2 Bit ADPCM",2,0,8000,0,0

141,"4 Bit ADPCM",4,0,8000,0,0

Result Codes

OK Valid range.

ERROR Otherwise, or if not in Voice Mode.
