speech before it is coded, 2000 doubles it a second time, 2828 doubles it a third time, and so on.

To decrease the incoming speech volume, multiply by 0.707 to approximately half the value or decrease it by 3 dB. Therefore, a value of 707 in the field reduces the volume by half, 500 by half a second time, and so on.

See Table 15 on page 192 for the relationship between the volume number and the actual change in volume expressed in decibels.

Note: The incoming speech volume value is set on a per-card basis for digital circuit cards.

13Enter the volume adjustment for all outgoing speech played on the circuit card in the Outgoing Speech Volume: field. Valid values range from

0 to 32000. The default is 707.

The value in this field and its effect are the same as described for the Incoming Speech Volume: field. Any adjustment is applied to recorded speech as it is processed for playback.

14(Optional) Enter the outgoing volume of speech in the Outgoing Text Volume: field. Valid values are 0 to 32000 (-30 to +30 dB). The default value is 1000.

Note: This field is displayed only if the optional SSP Text-to-Speech package is installed. This field only applies to SSP Text-to-Speech output volume. The LSPS output volume can not be changed.
