Trunk Disconnect

The UTI312 includes a Trunk Disconnect feature. The purpose of the Trunk Disconnect feature is to release the UTI312 from the trunk port in the event a user does not hang up the phone properly after making a page. If the UTI312 does not detect voice for the interface VOX time-out period, or if the interface default timer expires, the UTI312 will attempt to release from the trunk. When using the Trunk Disconnect feature, the PBX must have disconnect supervision available on the trunk port being used.The Trunk Disconnect feature is disabled by default. To set the VOX and default timers and enable the feature, refer to System Programming.

PBX Page Port Contact

In this configuration, the unit responds to a contact shorting the closure source to its return. When the short is removed, the page ends. Audio is provided to the system through a separate pair of dry audio input leads.

Make sure that the power is disconnected and all other connections are completed before proceeding. Move the slide switches on the UTI312 to the positions shown below. Use a modular telephone cord to connect the module to the phone system.

The center two conductors are used for dry audio (no DC voltage) and the connectors on either side are connected to the page port contact closure. The maximum resistance of the page port contact closure loop resistance is 1000 ohms. Open collector type outputs may also be used for controlling a page.The Trunk Disconnect feature is not available in this mode.

PBX Page Port VOX

In this configuration, the unit activates when audio on the page input is detected. Loss of audio allows the VOX timer to expire and ends the page.

Make sure that the power is disconnected and all other connections are completed before proceeding. Move the slide switches on the UTI312 to the positions shown below. Use a modular telephone cord to connect the module to the phone system. The center two conductors are used for dry audio and are not polarity sensitive. The Trunk Disconnect feature is not available in this mode.

Note:The default time-out is factory set to 30 seconds, and the VOX time-out is set to 6 seconds. If both the default and VOX timers are inhibited, there is no way to release the system from the page port VOX.
