If the speech interface is disabled and modem settings are unchanged, the
modem should work normally, as if the speech interface were not installed.
Line Item #2, the Speech Activity Channel, is an output from the speech interface board to the ZENO
®
-
3200. It allows the ZENO
®
-3200 to detect when speech is being generated and when it has finished.
Valid values for Line Item #2 range from 18 through 23.
Line Item #3, the Tone Detect Channel, is used to detect whether the caller is pressing a touch-tone key
on the telephone. Valid values range from 12 through 23.

The Modem Ring Detect Channel

, the Speech Activity Channel and the
Tone Detect Channel CANNOT specify the same channels.
Line Item #4, the Speech Switched Voltage, specifies which switched voltage is used to power the speech
interface board. The normal speech interface board is powered with 12 VDC. Contact Coastal
Environmental Systems if you require the speech interface board to be powered by 5 VDC. Valid values
for this line item are as follows:
0 (no switched voltage)
1 (5 VDC Switched A)
157
2 (5 VDC Switched B)
158
3 (12 VDC Switched A)
4 (12 VDC Switched B)
5 (12 VDC Switched C)
18 - 23 (a digital output)

6.11.4. Wiring Diagram
The speech/modem interface product contains three boards: the IDC modem, the speech engine board,
and the speech interface board. All connections to the ZENO
®
-3200 are through connectors on the speech
interface board, with a wiring harness provided by Coastal Environmental Systems. The following
diagram illustrates the wiring to the complete speech/modem interface product.

As with the Modem Switched Voltage (refer to Section 6.4), the Speech Switched Voltage could also be
configured to control one of the digital control channels (digital I/O channels 18 through 23). However, an external
switching device would be required to meet the voltage and current requirements of the speech interface.
