V-9972 Universal Page Interface Configuration Guide
Hardware Settings
Rev. 3.1
Page 2
The V-9972 Universal Page Interface accepts input from an FXO (loop start trunk) port, FXS (CO station) port or by IP network using
Session Initiation Protocol (SIP). The output from the V-9972 can be Line Level audio, FXO (loop start signaling) or audio transmitted
over the IP network using Valcom IP protocol. In addition to the basic capabilities, other features are available by license upgrade and
will be discussed in the appropriate sections in which they are configured.
The selection of which analog input and analog output will be active is set using DIP switches on the rear panel. These selections are
not configurable through software. The V-9972 must be power cycled for DIP switch changes to take effect.
Page Input (SW 6)
Two RJ11 jacks are provided for connecting the V-9972 to an analog phone port on a PBX, ATA, etc. One of these ports will be selected
as the active port using DIP switch 6. The ports are labeled according to the type of signaling provided. The port labeled FXO is intended
to connect to an FXS port (analog station port) and the port labeled FXS is intended to connect to an FXO (loop start trunk) port. 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 (SW 6 ON). The FXO port is a loop-start trunk port and can be used with a Station Port or FXS on a PBX (SW 6 OFF).
Page Output (SW 1)
The analog output of the V-9972 is accessed by screw terminals labeled One Way Page Out or Talkback Page Out. The One Way Page
Out (SW 1 OFF) provides a standard line-level audio tip/ring output. The Talkback Page Out (SW 1 ON) provides FXO signaling (loop
start trunk) for use with most multizone page controllers. One of these outputs will be selected as the active output using DIP switch 1.
Timeout Settings (SW 2 & 3, SW 4 & 5)
Two options are available for disconnecting calls automatically. The 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. If set to 0 (SW 2 & 3 both ON), the time-
out is disabled in hardware but may be set to a value between 0-600 seconds in software programming.
The Absolute Timeout indicates how many seconds the V-9972 will stay active for any caller. When the timeout setting expires, the
call is disconnected. Three values are available with the switch settings; additional options are available in software
programming. If set to 0 (SW 4 & 5 both ON), the timeout is disabled in hardware but may be set to a value between 0-3600
seconds in software programming.
