Telephone Interface
Wiring Connections & Setup
Telephone System Connections
The UTI312 connects to virtually any telephone system: PBX station lines and CO lines, PBX loop start trunk ports, PBX ground start trunk ports, and page ports.
Interface installation consists of setting the slide switches and connecting with modular (RJ11) telephone plugs. Refer to the appropriate procedure in this section to connect the UTI312 to the telephone system.
Note: In all cases, make sure that power to the UTI312 is disconnected before performing the installation.
PBX Analog Station Port
In this configuration, the unit answers immediately upon detecting a ring. As soon as it answers, the default timer andVOX timer are started.The default timer determines the maximum length of any page.TheVOX timer repeatedly resets as long as audio is detected on the line. If no audio is detected within the VOX time period, then the page will end. If audio continues to be detected, then the default timer will control page length.
The unit will also immediately disconnect if a loss of loop current CPC (Calling Party Disconnect) is detected.
Make sure that the power is off and all connections are completed before proceeding. Move the interface slide switch on the UTI312 to STATION.The other interface slide switch is not used and can be in any position. Use a modular telephone cord (minimum 2-conductor) to connect the UTI312 Station Port RJ11 to the phone system. The center two conductors are Tip and Ring and are not polarity sensitive (see below). Set Default and VOX timers (see System Programming).The timers can be independently inhibited.
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, the only way to release the system from the station line is through the use of a Calling Party Control (CPC) pulse.
7
PBX Loop Start Trunk Port
In this configuration, the unit supplies a 24V talk battery and loop current detection.When the unit detects a loop resistance between Tip and Ring, it activates.When the loop opens, the page ends.The unit follows the status of the trunk port.
Before configuring the UTI312 for a loop start trunk port, make sure that the power is disconnected and all other connections are completed. Move the slide switches on the UTI312 to the positions shown below. Use a modular telephone cord to connect the unit to the phone system.
The center two conductors are Tip and Ring (24V DC) and have a specific polarity as shown in the figure below. If the polarity that the trunk requires is opposite, you can use a reversing modular cord to make the connection or reverse the connection through a modular block.The Trunk Disconnect feature is available in this mode (description on page 9).
PBX Ground Start Trunk Port
In this configuration, the unit supplies 24V talk battery, a contact in the Tip circuit, and loop current detector in the ring circuit. When the ground start trunk grounds Ring, the unit responds by closing the connection to Tip, which completes the access procedure.When the loop is opened, the page ends.The unit follows the status of the trunk.
Before proceeding, make sure that the power is disconnected and all other connections are completed. Move the slide switches on the UTI312 to the positions shown below. Use a modular telephone cord to connect the unit to the phone system. Connect the GND STRT terminal on the UTI312 to the PBX ground. This is typically the AC ground for the PBX system. If the PBX is using the same Earth Ground as the UTI312, the Earth Ground terminal can be shorted to the GND STRT terminal instead of running a ground wire from the PBX.
The center two conductors are Tip and Ring (24V DC) and have a specific polarity as shown in the figure below. If the polarity that the trunk requires is opposite, you can use a reversing modular cord to make the connection or reverse the connection through a modular block.The Trunk Disconnect feature is available in this mode (description on page 9).
IMPORTANT - When the GND STRT terminal is connected to Earth Ground, it is important that none of the UTI312 system ground terminals are connected to Earth Ground. These terminals may accidentally be connected to Earth Ground when external equipment, such as a CD player, tuner, announcement device, etc., is connected to the UTI312.The UTI312 ground points are: the closure return terminal for the Trunk/Page Port jack, the contact closure (GND) and the left-most Dry Audio input terminal of the Override jack, the C terminal for the Night Ring, and the Tone Trigger input.The background music input and page outputs are transformer-isolated and are unaffected by Earth Ground. If the UTI312 system ground is tied to Earth Ground, then the UTI312 talk battery voltage will be shorted to ground and the unit will not function properly. For location of UTI312 system ground terminals, refer to the UTI312 Block Diagram.
8
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 theVOX 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.
9
Override Input
The Override is a feature that lets the caller take priority over all other paging functions and make a page.
The center two conductors interface directly to a Loop Start Trunk or a dedicated phone.When the trunk becomes active, the UTI312 goes into Override mode. A contact closure and dry audio source can also be used for the Override Input. The two conductors flanking the talk battery conductors provide a dry audio gateway into the system override. Override is activated by shorting the outermost conductors.
Maximum contact closure resistance is 1000 ohms. Open collector type outputs for controlling a page may also be used.The Override feature includes a quad beep pre-announce tone that can be enabled or disabled. (The default is enabled.) Make sure that the power is disconnected and all other connections are completed before proceeding. Plug modular cord into OVERRIDE (RJ11) jack.
90V Night Ring Input
The 90V Night Ring Input connects to an analog station line from the PBX or directly to a central office phone line. The UTI312 will follow the incoming ring signal cadence with a simulated ring or chime tone to the Night Ring zone group.
Note: The Night Ring feature has priority just above background music.There is a 5-second delay after the night ring stops before background music is restored (to bridge inter-ring pause).
