Output Port Selection (SW 1)
Two output connections are available on the V-9972. The Talkback Page Out connection provides FXO
(loop-start trunk) signaling. The One Way Page Out connection provides a standard tip/ring audio output.
The default level of the One Way Page Out is -10dBm, but can be changed in software to +2.2 dBm for
applications that require the higher output level.
Silence Timeout Selection (SW 2 & 3)
Silence Timeout indicates how many seconds the V-9972 will stay active after the audio input has stopped.
This can be used to disconnect a call after the caller has stopped speaking. Three values are available with
the switch settings; additional options are available in software programming.

Input Port Selection (SW 6)
Input Port selects which of the Page Input RJ11 jacks is active. The ports are labeled FXO and FXS to
indicate the type of signaling provided. The FXS port detects off-hook condition and provides dial tone
to the circuit. The FXS port can be used with a standard phone or loop-start trunk port. The FXO port
is a loop-start trunk port and can be used with a Station Port or FXS on a PBX.
